334 TUBERCULOUS DISEASE OF ANIMALS IN INDIA. 
November, 1852, it is just that Mr. W. Percivall has de- 
scribed in his vol. ii, at p. 118, as most predisposed to 
phthisis, and of course, other forms of tuberculous disease. 
But I do not blame Captain Apperley, whom I recollect 
only as a young sportsman, and, like his father, not un- 
friendly to veterinary surgeons. I never objected to any- 
thing offered for trial, by those who loved horses for sport. 
It was proved not to be specific in farcy many years past, but 
as an alterative. Mr. W. Percivall, in the last edition 6 On 
Diseases of the Chest, &c ,’ “ gives in phthisis, a tuberculous 
disease, Hyd. Chlorid. gr. x, in the Plummer’s ball, twice or 
thrice a-dav, to continue so as to slightly affect the mouth,” 
and, I am sure, not without experience of its benefit, or due 
consideration. It will be seen, therefore, in quoting so emi- 
nent an authority, I have not undervalued his treatment of 
bursautee. 
If Mr. Western reads on to p. 415, he will find it there 
stated by Dr. Willems, that “ the physical characters, the 
microscopical examinations, and the chemical analysis of the 
part where inoculation was made, prove that the local dis- 
order produced by the inoculation has the greatest resem- 
blance to the complaint, and the morbid lesions which are 
observed in the lungs of animals that have been diseased 
under the epizootic influences of pleuro-pneumonia.” In my 
paper on the ‘Contagiousness of Strangles,’ in No. 31, 
Veterinarian , for July, 1850, I stated “ that this form of the 
tuberculous disease (to which I attached what Mr. W. 
Percivall, in his new edition, calls a hybrid name), is, in 
general, the consequence of fever, from herding young ani- 
mals ; that we were aware, at the studs in India, that it 
could be communicated bv inoculation, and that other 
young animals were also liable to similar kind of fever ; and 
after the excitability is exhausted, by once having this fever, 
the young animals thrive, although again under the influence 
of the same exciting causes, without again being so liable to 
fever of any kind ; for, as in the case of older colts or adult 
horses that have once had this fever, the exciting cause must 
be more intense, as very foul stables, being placed on ship- 
board, &c., to again produce fever; in common language, 
older horses are said to have become seasoned to this herded 
manner of living. I use the word herded, because this fever 
occurs to young animals in eastern countries that are not 
stalled, and under these circumstances the fever is in general 
mild, “ common fever,’’ inoculations from the local affections 
of which sometimes fail. “ Whereas, when the fever occurs 
to closely-stalled colts, or older horses, it is a specific or
