scientific papers. The bomb delivered by Prof. Koch, although 
not loaded with dynamite, has exploded, and with such loud deto¬ 
nation that it has awakened all medical scientists for and against 
the subject. Experiments have been started all over, and be¬ 
fore a long time has elapsed crushing evidences will be forth¬ 
coming to show that Prof. Koch has made a mistake—or, rather, 
that he has misinterpreted the results of his own experiments. 
It has been my good luck lately to see cattle which are now 
subjects of experiments, and also to examine lesions taken from 
animals killed experimentally. So far the evidences are very 
satisfactory. Healthy young animals have in a comparatively 
short time shown unmistakable symptoms of tuberculosis ; 
others at their post-mortem revealed positive lesions, whose tu¬ 
berculous nature were readily demonstrated by the microscope 
and by cultures. That human and bovine tuberculosis are 
identical seems to have still numerous advocates, and it certainly 
will be difficult to ignore and deny the experiments of Chau- 
veau, Klebs, Kitt, Bollinger, Crookshank, and many others, 
even by taking into consideration the interesting results ob¬ 
tained by Theobald Smith, of Washington, and Frothingham, 
although they were different from those obtained by Prof. 
Thomassen, of Utrecht, and which he has related in the paper 
he read at the Congress of Kondon, where he made the impor¬ 
tant conclusions that from his own experiments it is difficult 
but not impossible to give bovines a generalized tuberculosis 
with pure cultures of bacilli from human source ; but never¬ 
theless the identity of tuberculosis in the two species remains 
an unshaken truth.

Pyaemia of Colts. —We are not aware that this affection is 
common in the States, and, yet, although governmental breeding 
stations do not exist with us, there are private farms where the 
conditions for the development of pysemic arthritis or paresia 
of colts may exist. The subject has received in Germany 
closer attention and given occasions for researches, among which 
I find those of the chief veterinarian of the haras of Wurtem-
