Ogle, after mentioning several cases of traumatic anosmia, suggests that a blow on the occiput is generally the cause. Legg reports a confirmatory case, but of six cases mentioned by Notta two were caused by a blow on the crown of the head, and two on the right ear. The prognosis in traumatic anosmia is generally bad, although there is a record of a man who fell while working on a wharf, striking his head and producing anosmia with partial loss of hearing and sight, and who for several weeks neither smelt nor tasted, but gradually recovered.

Mitchell reports a case of a woman of forty who, after an injury to her nose from a fall, suffered persistent headache and loss of smell. Two years later, at bedtime, or on going to sleep, she had a sense of horrible odors, which were fecal or animal, and most intense in nature. The case terminated in melancholia, with delirium of persecution, during which the disturbance of smell passed away.

Anosmia has been noticed in leukoderma and allied disturbances of pigmentation. Ogle mentions a negro boy in Kentucky whose sense of smell decreased as the leukoderma extended. Influenza, causing adhesions of the posterior pillars of the fauces, has given rise to anosmia.

Occasionally overstimulation of the olfactory system may lead to anosmia. Graves mentions a captain of the yeomanry corps who while investigating the report that 500 pikes were concealed at the bottom of a cesspool in one of the city markets superintended the emptying of the cesspool, at the bottom of which the arms were found. He suffered greatly from the abominable effluvia, and for thirty-six years afterward he remained completely deprived of the sense of smell.

In a discussion upon anosmia before the Medico-Chirurgical Association of London, January 25, 1870, there was an anosmic patient mentioned who was very fond of the bouquet of moselle, and Carter mentioned that he knew a man who had lost both the senses of taste and smell, but who claimed that he enjoyed putrescent meat. Leared spoke of a case in an epileptic affected with loss of taste and smell, and whose paroxysms were always preceded by an odor of peach-blossoms.

Hyperosmia is an increase in the perception of smell, which rarely occurs in persons other than the hysteric and insane. It may be cultivated as a compensatory process, as in the blind, or those engaged in particular pursuits, such as tea-tasting. Parosmia is a rare condition, most often a symptom of hysteria or neurasthenia, in which everything smells of a similar, peculiar, offensive odor. Hallucinations of odor are sometimes noticed in the insane. They form most obstinate cases, when the hallucination gives rise to imaginary disagreeable, personal odors.

Perversion of the tactile sense, or wrong reference to the sensation of pain, has occasionally been noticed. The Ephemerides records a case in which there was the sense of two objects from a single touch on the hypochondrium. Weir Mitchell remarks that soldiers often misplace the location of pain after injuries in battle. He also mentions several cases of wrong reference of the sensation of pain. These instances cannot be called reflex disturbances, and are most interesting. In one case the patient felt the pain from a urethral injection in gonorrhea, on the top of the head. In another an individual let an omnibus-window fall on his finger, causing but brief pain in the finger, but violent pains in the face and neck of that side. Mitchell also mentions a naturalist of distinction who had a small mole on one leg which, if roughly rubbed or pinched, invariably seemed to cause a sharp pain in the chin.

Nostalgia is the name generally given to that variety of melancholia in which there is an intense longing for home or country. This subject has apparently been overlooked in recent years, but in the olden times it was extensively discussed. Swinger, Harderus, Tackius, Guerbois, Hueber, Therrin, Castellanau, Pauquet, and others have written extensively upon this theme. It is said that the inhabitants of cold countries, such as the Laplanders and the Danes, are the most susceptible to this malady. For a long time many writers spoke of the frequency and intensity of nostalgia among the Swiss. Numerous cases of suicide from this affliction have been noticed among these hardy mountaineers, particularly on hearing the mountain-song of their homes, "Ranz des vaches."

This statement, which is an established fact, is possibly due to the social constitution of the Swiss mountaineers, who are brought up to a solitary home life, and who universally exhibit great attachment to and dependence upon their parents and immediate family. In the European armies nostalgia has always been a factor in mortality. In the Army of the Moselle, and in Napoleon's Alpine Army, the terrible ravages of suicide among the young Bretons affected with nostalgia have been recorded; it is among the French people that most of the investigation on this subject has been done. Moreau speaks of a young soldier in a foreign country and army who fell into a most profound melancholy when, by accident, he heard his native tongue. According to Swinger and Sauvages women are less subject to nostalgia than men.

Nostalgia has been frequently recorded in hospital wards. Percy and Laurent have discussed this subject very thoroughly, and cite several interesting cases among emigrants, soldiers, marines, etc. Hamilton speaks of a recruit who became prostrated by longing for his home in Wales. He continually raved, but recovered from his delirium when assured by the hospital authorities of his forthcoming furlough. Taylor records two cases of fatal nostalgia. One of the victims was a Union refugee who went to Kentucky from his home in Tennessee. He died talking about and pining for his home. The second patient was a member of a regiment of colored infantry; he died after repeatedly pining for his old home.

Animals are sometimes subject to nostalgia, and instances are on record in which purchasers have been compelled to return them to the old home on account of their literal home-sickness. Oswald tells of a bear who, in the presence of food, committed suicide by starvation.
