The first is derived from tubercle, “ a little swelling/' or a 
“ knot/' 
The second, from a Greek word, signifying “ swine evil/' or 
“ swine swelling/’ from a notion that pigs were subject to it, and 
dates back even from Pliny. 
The third, derivation uncertain, but is thought to be from 
words signifying “ I heap up,” or “ I grow insensibly.” 
Each of these terms (as also “ king’s evil,” as it is called in 
the human subject) are unsatisfactory, and lead to no idea of the 
true pathology of the disease; indeed, it would be difficult to coin 
a term truly indicative of this peculiar state of the system, and, as 
Dr. Bennett says, “ it is questionable whether it is worth while, 
since it (tubercle) is so universally used and understood to sub¬ 
stitute another for it.” 
Scofulous or strumous tubercle would each distinguish it from 
other abnormal products. 
Tuberculosis is generally arranged under three heads (or rather 
its different characters); hence we have— -(a) miliary or granular 
tubercle, from its resemblance to small granulations, and from 
its millet-seed shape and size; most frequently found in the 
meninges of the brain and spinal cord, on the surfaces of bones, 
the pleura, and peritoneum, and, in the horse, in the lungs, as an 
accompaniment and consequence of glanders; and here I may 
state my opinion that glanders is nothing more than a form of 
tubercle, produced by the same causes, running the same course, 
and ending in the same manner, with identical symptoms, viz., 
cough, discharge from the nose (the horse does not expectorate), 
ulceration of air-passages. With regard to the ulceration of the 
Schneiderian mucous membrane, it may be asserted that it is alto¬ 
gether dissimilar to that of tubercle, but in reality it is not so; 
and we must not forget that ulceration is only the local mani¬ 
festation of a systemic disorder, and differs according to the ana¬ 
tomical characters of the structures implicated—consumption of 
the soft structures of the body, and miliary tubercles in the lungs, 
frequently coalescing and becoming putrid from exposure to air 
constituting vomicse. 
(a) Miliary tubercle also occasionally affects the muscular struc¬ 
ture of the heart, one case of this kind being on record by Mr. 
Gowing. 
(b) Infiltrated or diffused, when found in masses more or less 
large, distributed within, and on the surface of organs, and very 
frequently accompanied by or associated with large quantities of 
true inflammatory lymph, which glues those surfaces, not only 
together as one intestine to the other, but also to the internal 
parietes of the cavities in which they are contained, as the intes¬ 
tines to the abdominal walls.
