and other college stories. But between this and I bling in purpose and structure the already famous "Half-hour Series." They promise to supply "books in a form so convenient and handy that the volume may always be carried in the pocket, ready for use on the train, on the steamboat, in the horse-car, at moments snatched at twilight or bling in the woods-at all periods of rest or leisure, whether in town or country." The earliest of this series are two novelettes. Jet: her Face or her Fortune, by Mrs. ANNIE EDWARDS, is a simple story of the experience of a girl with an attractive fortune-hunter, from whom she happily escapes. Incidentally it gives a good glimpse of life at the Continental watering-places. A Struggle is by BARNET PHILLIPS, the author of the brilliant story, "On a Melon Schooner," published in this Magazine last October. The scene is the field of battle in the Franco-German war; the hero is an American, rather idealized, but a genuine hero; the characters, which are few, are distinctly individualized; and the story is so prettily told, and the love and heroism are made so prominent, that there is nothing appalling in the tragic background. It is a notably good novel.-In Dosia, of the "Cobweb Series" (Estes and Lauriat), the translator of Sidonie introduces to the American public the French novelist HENRY GREVILLE. Dosia is a story of Russian life; some of its characteristic scenes are very vividly depicted, as, for example, the skating rink; and there is a charming vivacity about the whole story, after we once get into it, which is peculiar to the best French writers of fiction.-His Inheritance, by ADELINE TRAFTON (Lee and Shepard), is so mournful that we can commend it only to those who enjoy the tragedy of fiction. The cunning of a shrewd mother overreaches itself and destroys two lives that but for her treachery might have been made happy in a commingled love. The pictures of pioneer and camp life on our borders are well drawn.-There is nothing to distinguish the latest of the "Leisure Hour Series," Hathercourt, by Mrs. MOLESWORTH (Henry Holt and Co.), from the ordinary English love story except that it is rather poetically wrought out. Fair Harvard there is a striking contrast, the one being written by a pessimist, the other by an optimist. Tom Hammersmith, the hero of the story, goes through his college career with the greatest éclat. He is a fine scholar, a leader in the boat club, prominent in the glee club, suc-bed-time, while sitting on the sea-shore or ramcessful in the love-making, and generally great in every thing. The external scenery is faithful and exact, almost photographic. The inward college life is highly colored. Tom Brown at Oxford was a faithful college picture; Hammersmith at Harvard is a pure college romance.-Innocents from Abroad, by the author of Tom's Wife (G. W. Carleton and Co.), represents a Brazilian and his son visiting this country and looking at American life, or rather on New York city life, through a Brazilian's eyes. It is a burlesque founded on truth. It represents not the realities, but the gigantic shadows which they cast, in which every fault and foible is magnified. We should be sorry to have any foreigner take his idea of America from this book; but Americans might read it with profit, if not with pleasure.-Miriam's Heritage, by ALMA CALDER, and Mag; a Story of To-day (Nos. 3 and 4 of "Harper's Library of American Fiction"), are both of them distinctively religious novels, though neither of them is in any sense dogmatically so. Neither is written to commend a creed, a system, a philosophy, or a church; both of them to show the power of genuine Christian love. The scene of Miriam's Heritage is the Upper Delaware River; the time, half a century or so ago, before the New York and Erie Railway was built; the heroine, Miriam Morgan; her heritage, the work of carrying on the home life after her mother's death and her father's paralysis, the work of managing his business affairs, and of so managing them as to make both home and business a means of reclaiming the outcast, educating the ignorant, and developing in culture, refinement, industry, thrift, and intelligence the entire community. In Mag the scene is an unlocated point in the South; the heroine, Miss Bertie Lee.

Thanks to Miss Mulock's sympathetic heart and simply eloquent pen for this sorrowful but significant story. Thanks, too, for the life itself, that stands as a witness to the heroism of common life in unexpected places. Neither Dickens nor Farjeon has ever conceived a story of the pitiful yet inspiring tragedy of poverty to compare with this simple and "ower-true tale" of the life of the aspiring but quenched and prematurely dying poet. If 7e criticise the book at all, it is that Miss Mulock, ir the fear lest her sympathies run away with her critical judgment, hardly gives to her hero credit enough for the merit of his literary productions. For they have real merit; and under brighter suns he might have developed into a real con-able authenticity. The author, who is reported tributor to English literature. Philochristus (Roberts Brothers) is a very unique book both in its literary and its theological aspects.

SUMMARY OF SCIENTIFIC PROGRESS. Astronomy.-The Naval Observatory at Washington has received many observations of the transit of Mercury on May 6 from private observers (some forty or more), besides the results of the parties of the Coast Survey, of the Engineer Department of the army, and of its own expeditions. The data of the French party at Ogden were also placed at its disposition. on the vertical diminution of temperature in the atmosphere. Their essay goes over a ground already pretty fully traversed by Thomson, Rege, Haun, etc., but presents some features of the subject in a rather new aspect. Their formulæ relate to a stationary atmosphere and to ascending and descending currents. Linss, of Darmstadt, calls attention to the importance of considering the inertia of the atmosphere (Lamont's Theory) in explaining the diurnal barometric variation. In studying the direction of the motion of the clouds, he finds that the barometer rises less in proportion as the angle is larger which the direction of the lower clouds' movement makes with the direction of the barometric gradient. Captain Hoffmeyer, of Copenhagen, in some notes on the recent winter in Iceland, states that in the autumn of 1877 very beautiful weather prevailed, the temperature of September being the The preparations for observing the total solar eclipse of July 29 are in a forward state. The Naval Observatory has an appropriation of $8000, which will be devoted to sending parties to the field, under Professors Newcomb, Hall, Harkness, Eastman, and Holden, of the navy; and Professors Langley and Stone. Mr. Trouvelot and Dr. G. W. Hill are also sent by the observatory. Professor Watson will photograph the eclipse with a horizontal photoheliograph belonging to the Naval Observatory. Professor Young, of Dartmouth, has formed a party to go from Prince-highest in thirty years. A sudden change in the ton College. Several distinguished Englishmen have already signified their intention of coming. Dr. Draper, with Professors Barker and Henry Morton, of New York and Philadelphia, intend going. Among the observers sent by the Naval Observatory are Professor O. B. Wheeler, of Detroit; Professor Wright, of New Haven; Professor Robinson, of Rochester; Alvan G. Clark, of Boston; Professor Boss, of Albany; Professor Hastings, of Baltimore. weather occurred October 11, and a very stormy period intervened, culminating in a hurricane from the northwest, with a very cold snow-storm on January 6 and 7, 1878. February and March were mild and damp. Deura, of Mencalieri, announces that it has been decided to give the meteorological station on the summit of the Stelvio Pass the name, "The Secchi Station at Stelvio," in permanent commemoration of the great work accomplished in In Meteorology, we have received during June, Italy by Father Secchi, who, among many other among other pamphlets, one by Carpmael, of To- things, began in Rome the publication of a teleronto, on the reduction to sea-level of the read-graphic meteorological bulletin a year before Leings of the barometer. His formulæ are convenient, and quite as accurate as the conditions of the problem admit of; they differ, however, very much from those in the method adopted by the Army Signal Office. Ruberson has examined the diurnal variations of temperature of Swedish stations, and finds (1) the non-periodic variation is throughout the year greater than the periodic; (2) the difference of these two variations is greatest in winter; (3) during the remainder of the year the difference is nearly constant; (4) the difference-2.66 mm. in spring, 2.82 in summer, 3.03 in autumn-can be assumed to hold good apparently for the whole of Sweden. The difference in question is greater for a maritime climate, and least for one of a continental type. In a memoir upon atmospheric pressure, Ragone gives some important measure of the correction due to capillarity of the meniscus form of the top of the mercurial column. In a siphon barometer the height of the meniscus in the two legs is seldom the same. In comparing any barometer with a standard, he finds the relation of the former to the latter to vary with the pressure, temperature, and diameter of the tubes. Buys Ballot communicates a highly important memoir containing tables of monthly mean pressures at the stations for which the departures are given daily in the Meteorological Bulletin of the Netherlands. The large number of stations and the careful revision of the data render this a very welcome addition to our knowledge of the distribution of atmospheric pressure in Europe. Goldberg and Mohr have published two articles | verrier started the Paris Bulletin. The discovery by Main at Oxford that the annual mean direction of the wind fluctuates with the variation of the solar spots has stimulated Hornstein to a similar investigation for Prague. He finds results perfectly agreeing with those of Main, and also indications of still further coincidences between these phenomena. In addition to their memoir on the distribution of temperature in the air, Professors Goldberg and Mohr have also published a short elementary essay on vertical currents in the atmosphere. They treat of ascending and descending currents, and illustrate their formulæ by numerous examples, and especially urge the importance of knowing more than we do about the condition of the outer or higher atmosphere with reference to temperature and moisture. Lieutenant J. Spindler publishes, in an appendix to the St. Petersburg Daily Meteorological Bulletin, a valuable collection of the paths of storm centres that have passed over Northeastern Europe during 1873-77. The tables and results can not be condensed, but will afford material for testing future theories of storm move ments. Goldschmid has invented a very delicate selfrecording attachment to his form of aneroid barometer. A test series of observations at Zürich showed that his apparatus gives quite as good results as ordinary readings. Thiesen publishes an interesting memoir on the extent of our atmosphere. Having regard to all that at present is known of the physical properties of air, he finds that contradictions arise at almost every step, and that we are not as yet | Thompson proposes to improve the sibilants in able to indicate the limit. the phonograph by placing a strip of card or watch spring across the opening edgeways, so that the voice impinges on the edge of the strip. The aspirates are also well spoken by such an instrument. In Physics, Stanley has proposed the use of the pendulum for the purpose of registering cumulative temperatures or pressures. The pendulum consists of a steel cylindrical tube 32 inches long and 1 internal diameter, closed at Vincent has made a careful study of the use both ends, to the upper of which is attached a of methyl chloride in the production of cold.

The clock is arranged to count beats in units up to ten millions, and the number of beats per day, week, month, or year becomes the unit of temperature or pressure for the period. The upper chamber contains a conical plug for the purpose of automatically effecting certain corrections, especially that due to the expansion of the case. For a pressure apparatus, which the author calls a chronobarometer, the external tube is dispensed with, except at top and bottom. Mann has described in Nature an improved method of projecting Lissajou's curves upon the screen. On a base board two reed boxes are placed, one horizontal, the other vertical, capable of slight adjustment, so arranged that the reeds face each other. These reeds are inserted in reed plates, clamped to the face of the boxes, the vertical one giving the fundamental note, the horizontal consisting of a series giving all the intervals up to the twelfth. The reeds themselves are similar to those used in harmoniums. To each, about an inch from its free end, a small mirror of silvered glass is attached. By means of an air current, controlled by two taps, the Lommel has communicated to the Physical Soreeds may be thrown into vibration, the rate be-ciety of Erlangen a memoir on fluorescence, in ing controlled within certain limits by the air which he divides all fluorescent bodies into three pressure.

The gaseous mixture being passed through an acid, the alkaline bodies are removed, and the methyl chloride is left pure for condensation. On exposure of the liquid to the air it at once boils for an instant, until the temperature falls to -23°. If a current of air be passed through it, a temperature of -55° is obtained, in which mercury freezes. Placed in a closed vessel and the air exhausted, a very low temperature is obtained, which may be utilized in the production of ice. Methyl chloride is sold in the liquid form in Paris at four francs the kilogram. Arzrimi, in studying the crystalline properties of various organic bodies, has discovered that triphenyl-benzene possesses the property of double refraction to a degree surpassing that of any other crystalline body yet known. In substituted compounds he shows also that the introduction of the nitro-group invariably causes a much slighter change in crystallographic properties than when hydrogen is substituted by bromine or by iodine. only those rays of the fluorescent spectrum which are of a less refrangibility than the ray itself, and the third embracing those substances whose fluorescent spectrum consists of two parts, one of which corresponds to fluorescence of the first, and the other to fluorescence of the second order. He enumerates nine bodies belonging to the first class, twenty-five of class second, and seven of class third. He has not been able to prove that class three is a mixture of classes one and two. Ellis has described some results obtained by Jenkin with an apparatus by which he obtains vertical sections of the impressions made on the tin-foil of the phonograph, magnified 400 diameters, and called "speech curves." In the word tah, for example, intoned, there is first the "preparation," the curve gradually but irregularly rising; then the "attack"-a bold serrated precipice, with numerous rather sudden valleys; next the "glide"-a perfect tumult of curvatures, which gradually settle down into the "vowel" Abney has described to the London Physical proper.

The latter plates are sensitive to the red and ultrared rays, and photographs of the spectrum were exhibited extending from the line C to a wave length of 10,000, the ultra-red showing remarkable groupings of lines. He explained the reversing action obtained by Draper at the red end as an oxidizing action, and found it to be accelerated in solutions of permanganate, hydroxyl, etc. Hughes has presented a paper to the Royal Society on an instrument he has devised for magnifying weak sounds, and which he calls a microphone. In its best form it consists of a stick of The Bulletin of the Société d'Anthropologie for gas carbon placed vertically, and supported loose-1877 comes to us freighted with the accustomed ly between two small blocks of carbon fastened to a piece of thin board. When an electric current passes through the carbon, an ordinary telephone being in circuit, the slightest jar, and even the vibrations of the voice, are sufficient to interrupt the contact at the surfaces. This, varying the current strength, causes a sound in the receiver. The sensitiveness of the instrument is surprising, the ticking of a watch, the brush of a camel'shair pencil, the tread of a fly, all being readily audible at the distant telephone. The principle of varying the resistance of a circuit by varying the number of points of contact in it, upon which these phenomena depend, was first utilized by Edison in January, 1877, and has within a year been brought to great perfection in the construction of the carbon telephone transmitter. The disks of carbon, or of silk thoroughly impregnated with carbon, he has also used in his tasimeter, which in various forms serves as a thermometer, barometer, hygrometer, and anemometer in a new and simple rheostat, and in a In Zoology, we have, among the novelties offernew relay contrived expressly for the relaying of ed us the past month, Haeckel's Das Protistentelephone currents.

Like other Rotifera, this species lays two sorts of eggs, summer and winter ova. The latter are produced in the spring, but are not laid until later, the process of oviposition being delayed much longer than in that of the summer eggs. The young notommatas form in the galls, make their exit by openings which are made spontaneously at the summit of the adventive branches of the Vaucheria.
