berculosis or some other disease. Villemin, Roll and others did not 

 succeed in producing the disease in sheep, by inoculation, while Co- 

 lin and Zlirn state that the majority of their experiments in this 

 direction failed, though they succeeded in a very few cases. 



Goat. — Tuberculosis has been found in this animal in a few in- 

 stances. 



Hens. — Dr. Ribbert of Bonn states that tuberculosis sometimes 

 attacks hens, and may even become epidemic in a flock. He found 

 the bacilli of tuberculosis in abundance in the walls of the intestine, 

 and also in the spleen and liver. 



Mr. Sutton of the London Zoological Garden, who made an ex- 

 amination of more than a thousand birds of various species, informs 

 us that those most commonly affected by this disease are the graniv- 

 orous birds, and those which feed on fiuit. Those most liable to the 

 disease are the hen, peacock, grouse, guinea-fowl, pigeon and part- 

 ridge. 



Rabbits and guinea-pigs are very susceptible to the disease, proba- 

 bly nearly as much so as the bovine race. Other animals in which 

 tuberculosis has been found are cats, dogs, mice, rats, also caged 

 lions, monkeys, kangaroos, deer and gazelles in a zoological garden, 

 and a rhinoceros in Barnum's Museum. According to .Satterthwaite, 

 frogs are subject to miliary tuberculosis, but this seems almost in- 

 credible. 



HISTORY OF TUBERCULOSIS. 



This disease under one name or another has been known from the 

 earliest times. According to ancient authors on medicine as Hippoc- 

 rates, 400 B. C, Aristotle, 330 B. C, Galen, 180 A. D., and others, 

 it consisted of abscesses or ulcers in the lungs. The term ''tuber- 

 cle," as meaning a solid node, is first met with in the works of those 

 who paid especial attention to the anatomy of the human body. 

 Silvius, in 1695, first advanced the idea that phthisis sometimes re- 

 sulted from larger or smaller nodes which finally led to abscesses and 

 the formation of cavities in the lungs. Manget, in 1700, stated that 

 in the dissection of a person who had died of phthisis, he discovered 

 small nodes of the size of a millet seed in the lungs, liver, spleen and 

 kidneys. These small bodies are now called miliary tubercles, 

 wherever fouud. He also described the cheesy structure of these 

 nodes, but supposed them to be minute lymph glands. Other writers 

 of that date held similar views.
