Capillary Theory, VIII. Acoustics. IX. Heat. X. Optics. XI. Electricity, Galvanism, and Magnetism. XII. Concluding Observations.

By THOMAS WEBSTER, M.A. Camb.

The Author's especial aim in this work has been to familiarize the student with processes. reasonings, just inferences, and inductions, rather than to present to aim a collection of facts; and he trusts that he has, in some measure, succeeded in compiling a Treatise exhibiting, in a mathematical form, but without mathematical technicalities and symbols, the various processes by which the establishment of any proposition in Physics is arrived at.

"This work merits considerable praise for simplicity of style and felicity of illustration; it is easier to read than Arnot's book, as it does not require the same study and fixity of attention, and it is therefore better suited to those who wish to acquire an elementary knowledge of Physical science."—Athenæum.

Edited by the REV. BRANDON TURNER, M.A.

"The edition before us is superior to its predecessors, since it is not only more accurate, but it contains nearly double the quantity of matter."Athenæum.

"We prefer the additions to the original. Mr. Turner has bestowed more thought and care on his work than professional avocations allowed Tytler to afford. We are bound to state that we could not easily point out a work containing so much historical information in the same space as the present volume."-League.

*The Appendix, which is now added, contains a collection of examples, illustrative of, and connected with, the principal propositions advanced in the body of this work. A further object is likewise proposed, viz. to familiarize the student of Natural Philosophy with the processes required for the elucidation of physical science. These have been made perfectly intelligible to all who are acquainted with the ordinary operations of Arithmetic, the first principles of Algebra, and Euclid's Elements of Geometry.

Some unworked questions, with answers, are added to the examples, for practice by the pupil. In all cases in which the arithmetical processes are referrible to established formulæ, such formulæ have been inserted. The principles being thus understood, the questions may be varied, and any number may be added, according to the capacity of the learner, and the judgment of the teacher.
