ficalt and audible respiration with a grunt. When the digestive 
organs are the seat of the disease, capricious appetite, bloating, 
tenderness on pressure, faeces soft or constipated, and in last 
stages thin and foetid. The first evidence where the digestive 
organs are involved, the animal does not hold its own in flesh and 
general condition. 
The udder is not infrequently a seat of the trouble, which 
shows itself in the form of small nodules or circumscribed mam- 
miets, which do not yield readily to the treatment for garget, for 
which they are often mistaken. The nervous system is not ex¬ 
empt from its ravages, as seen in cases of paralysis or excitement, 
when the spinal cord or brain is affected. 
The generative organs are not infrequently involved, as seen 
in nymphomania or continual bulling. 
That the lesions of tuberculosis are not confined to any special 
tissue or organ, can be seen by the various symptoms it presents, 
as well as the different ways the virus may enter the system. 
Of 200 cases that were inspected by Goring of Bavaria, in 88 
cases the lesions were confined to lung and serous membranes; in 
67 cases the lesions were confined to lungs only; in 33 cases the 
lesions were confined to serous membranes only, and in 12 cases 
where the disease was in other organs. 
Again in 1,596 cases of tuberculosis, carefully investigated in 
the Grand Duchy of Baden, 21 per cent, with lung lesions only ; 
28 per cent, with peritoneal and pleural lesions only; 39 per 
cent, with lung and pleura; 9 per cent, with general tuberculosis; 
3 per cent, with genital organs. 
It is a well-established fact that heredity has an influence in 
its propagation, and it may be transmitted by the male as well as 
by the female. Notwithstanding the above fact, animals may be 
born from tuberculous parents without any predisposition to the 
disease, and multiply the same as if from perfectly healthy ances¬ 
tors; still, the predisposition may be inherited from tuberculous 
parents. 
That it is an infectious disease has been well established. As 
long ago as 1780, Dr. Wichmann, court physician at Hanover, 
stated that phthisis was transmitted when exposure to infection
