have often observed, that the perspiration or breath of dogs labouring under
variola
emits a very unpleasant odour. This smell is particularly observed at the commencement of the desiccation of the pustules, and when the animals are lying upon dry straw; for the friction of the bed against the pustules destroys their pellicles, and permits the purulent matter to escape; and the influence of this purulent matter is most pernicious. The fever is increased, and also the unpleasant smell from the mouth, and that of the fæces. In this state there is a disposition which is rapidly developed in the lungs to assume the character of pneumonia. This last complication is a most serious one, and almost always terminates fatally. It has a peculiar character. It shows itself suddenly, and with all its alarming symptoms. It is almost immediately accompanied by a purulent secretion from the bronchi, and the second day does not pass without the characters of pneumonia being completely developed. The respiration is accompanied by a mucous
râle
which often becomes sibilant. The nasal cavities are filled with a purulent fluid. The dog that coughs violently at the commencement of the disease, employs himself, probably, on the following day, in ejecting, by a forcible expulsion from the nostrils, the purulent secretion which is soon and plentifully developed. When he is lying quiet, and even when he seems to be asleep, there is a loud, stertorous, guttural breathing.

Mange
The existence of certain insects found burrowing under the skin of the human being, and of various tribes of animals, has been acknowledged from the 12th century. In the 17th century, correct engravings of these insects were produced. On the other hand many doubted their existence, because it had not been their lot to see them. In 1812, Galés, a pupil in the hospital of St. Louis, pretended to have found some of them. They were put into the hands of M. Raspail, of Paris, who proved that they were nothing more than the common cheese-mites; and substituted by Galés for those seen by Bonomo.
