or headache. The conj unctiva: were habitually congested, and he could not endure, without considerable suffering, a more than ordinary strong light.

Among the aberrations of the sense of sight precursory of cerebral disease are the following a—Seeing objects cut in half, double vision, inversion of objects?‘ A lady who had complained of being out of health, of slight headache and partial deafness, found, in the early part of one morning, that her sight was disordered. In attempting to read a book, she remarked that the printed letters and sentences were running one into the other. Subsequently the page appeared as if a piece of finely glazed paper had been placed over it, through which she was just able to discern the letters. In the aflsernoon of that day she had an attack of apoplexy which ended fatally!

Vitiated perception is one of the common precursory symptoms of apoplexy. A lady of vigorous and culti~ vated understanding, whom Dr. Cheyne attended, was menaced with apoplexy. Previously to the attack, she complained of being annoyed by numerous unusual appearances in luminous bodies; the flame of a candle was MORBID LUMINOUS PHENOMENA. 585

" Dr. Wollaston relates that it twice occurred to him not to be able to see but on one side of the axis of vision. The first time the left side of each eye was affected; he saw but the half of a man's face or of any object he looked at ; and in attempting to read the name Jonssos over a door, he saw only

. SON, the commencement of the name being totally obliterated from his view: the complaint was of short duration. About nineteen years afterwards the visual phenomenon recurred; this time the right side of the eye, about three degrees from the centre of the retina, was affected, and its duration was ten minutes. Two analogous cases are also mentioned by Dr. Wollaston. Desmoulins states that M. Arago has experienced this affection of vision three times: on the first two occasions objects situated to the right of the axis of vision were invisible; the third time he saw objects on the right only of this axis. The same author notices also the following remarkable me. In consequence of a cerebral fever, the external side of the left retina of M. de M— became insensible: with his eye he saw objects only situate to the left of the centre of vision, and, as at the same time there was an outward deviation of the axis of this eye through a paralysis of the nerve of the third pair, when he employed both eyes, he saw objects double; but, what was still more

singular, the right eye being closed, he saw with the left eye the objects removed from twenty to twenty-five degrees to the right of their real position. ' “ Clinique.”

enlarged to the shape of a tulip, and with a red centre; the moon appeared oval with a central portion of a bright scarlet. All distant objects were hazy, yet she read and wrote without any difliculty.

A gentleman complained a few hours before he was attacked with paralysis of his being able to recognise only half of everything he saw. If he looked at a person, there appeared to be but one eye, half of a nose, and mouth. In another case, every part of the body was enveloped in a thick mist. This was among the premonitory signs of a severe attack of phrenitis, and existed some days before severe headache excited alarm as to the state of the brain.

then speaking of the affections of vision connected with cerebral haemorrhage, Andral remarks, “Sight is sometimes, but not always, disturbed. We see individuals struck down with apoplexy and affected with paralysis and loss of sensation, where, nevertheless, consciousness and vision remain. Difl'erent sensations, resulting from disturbance of this function, are experienced by patients, who describe them in different ways; some say that they have motes before their eyes; others, they see the light as through a cloud, just as on the onset of cataract—yet here the crystalline lens is clear; others see various colours. Sometimes, those who at a later period are attacked with apoplexy, have the sight modified for a longer or shorter time before the attack in such a manner that all objects appear double, a symptom which is sometimes transient, being present one day and not another. In other cases the loss of sight is nearly complete, but such cases are very rare. When the sight is lost, this may take place on one side or on both ; and this blindness coincides with the loss of numerous other senses.”

Photopsia, or the appearance of luminous phenomena, objects in a state of ignition, or surrounded by a phosphorescent halo, are common incipient symptoms of acute disease of the brain.

The late Dr. James Johnson relates the particulars of an interesting case of the kind. “ A distinguished artist for several years suffered from photopsia, to which afterwards headache and diminution of vision were added, terminating in complete blindness. Nevertheless the luminous phenomena continued night and day, occasionally assuming the appearance of angels with flaming swords, whose movements were apparently accompanied by an electric light. The forms, however, frequently varied. The mental powers of the individual remained unimpaired, and whenever he went out he was very attentive to everything that did not require eyesight. In the spring of 1835 he had an apoplectic seizure which deprived him of movement, consciousness, and speech. There was complete paralysis of the sphincters, and the pupils were dilated. He recovered from this condition, and after a few weeks was again able to go about the town and attend to his business. But the visual phenomena returned, and the sight was as painfully dazzling, and more continuously so than before. In the month of August an apoplectic attack occurred, and death ensued in three days. The right lateral ventricle of the brain was found after death to contain nearly three ounces of clear fluid. The left was full of bladders resembling hydatids of various sizes, and containing fluids varying in consistency. This accumulation sprung from the floor of the ventricle by a kind of pedicle, and penetrated into all the recesses of the cavity, pushing its branches forwards so as to extend the thalamus of one side into the opposite half of the brain, destroying everything that opposed its passage. Both thalami optici were converted into a pulp, as well as the


whole anterior lobe, which was so difiluent as scarcely to bear the slightest pressure. The optic nerves were compressed by the hydatids so as to present a mere thready appearance. Pressure at the back of the neck caused great uneasiness, extending to the lower trunk and extremities. It was not pain, but a horrid feeling that was induced. This pervaded the whole frame, and it was Only by the greatest entreaty that he could be induced to permit a repetition of the manual examination. The sensibility had now so much increased that simply touching was sufficient to renew these distressing sensations. A pint of blood was taken from the arm. During the operation the vision returned. He said he saw three women standing behind the gentleman who was bleeding him. Being asked were they as large as life? he replied, ‘that they were rather low,’ and pointed to the place where they stood. It was inquired, ‘ Had he ever seen them before?’ ‘ No.’ ‘ \Vere they speaking to each other?’ ‘ No.’ ‘ What were they doing?’ ‘ They were usually minding their business, but sometimes stopped to watch him, and kept their eyes fixed on his for some moments.’ The sense of feeling was quite as much disturbed and illusive as that of sight, for in a few moments after he called out, that he felt ‘ one of them thumping up against that part of the bed on which he lay ;’ and presently again looked abruptly behind him, saying, ‘ that somebody had hit him two or three times on the back.’ All this was very different from the usual raving of the insane, as he scarcely felt the impression before he was himself aware of its being an illusion. In fact, his chief distress arose from the alarming nature of the disordered perceptions. ‘ Rid me of these sights and sounds,’ was his entreaty, ‘ and get me some sleep, or I shall lose my senses 1’

“ Active purgatives were exhibited, after venesec

tion was performed. Subsequently a blister was applied over the ninth dorsal vertebra with great benefit. He soon recovered under the continued use of gentle alterative aperients, combined with counter-irritation.

“ He had arecurrence of the attack some months after in consequence of hard drinking; but though he complained more of the head, especially at the back of it, there was no material fulness or frequency of the pulse, or febrile irritation. He was relieved by purgatives and blistering, and was afterwards treated with camphor and other nervine medicines.”

A nobleman, for some weeks previously to an attack of apoplexy, was subject to a curious phantasmal phenomenon. He, on several occasions during the day when suffering from acute headache, saw clearly a spectral image resembling himself. This form of halluci~ nation is termed deuteroscopia. The phenomenon is considered of rare occurrence, even among the insane. Aristotle refers to this type of illusion in his essay, “ De filemorid et Reminiscenfid,” but it is explained more at length in his Meteorology.

A certain Antipheron,-Aristotle says, when he was walking, saw a phantasmal reflexion of himself advancing

' towards him. A traveller who had passed a long time without sleeping, perceived one night his own image, which rode by his side. It imitated all his actions. The horseman having to cross a river, the phantom passed over it with him. Having arrived at a place where the mist was less thick, this curious apparition vanished. Goethe relates having had a similar hallucination. This form of hallucination is frequently observed during the delirium of typhoid fevers.‘
