quite too rapid to permit of total absorption, and in that way 
learned that we could, without discomfort or injury, have it 
quickly expelled, and thus we learned by comparison with 
Colin’s and Gohier’s experiments that we may at our option, 
by varying the rate of administration, either have the liquid 
absorbed or rejected, or partly absorbed and,in part expelled. 
At some times we apparently had 50 per cent, or over absorbed, 
though always given rather rapidly, while in other cases nearly 
all appeared to be rejected. 
We have been led to hope that in spite of the meagre ex¬ 
perience upon which we have based our communication, the 
facts and suggestions will suffice to lead others to study the 
plan of treatment herein outlined, with a view to developing a 
successful method of therapeutics in this heretofore baffling 
group of affections. 
INTERESTING TUBERCULIN REACTIONS. 
By F. S. Schoenleber, M. S. A., D. V. S., Assistant State Veterinarian, 
McKillip Veterinary College, Chicago. 
During the month of September, 1897, the attention of the 
State Board of Live Stock Commissioners was called to a herd 
of dairy cattle at Hebron, Ill. From the fact that the owner 
had “lost half a dozen cows during the summer,” and from the 
condition of the remaining portion of the herd it was evident 
that tuberculosis was present, although it could not be detected 
in but perhaps two or three cases. A tuberculin test was there¬ 
fore instituted October 26-28. There were thirty-five milch 
cows in the herd, all grade Holstein and Shorthorn. Thirty- 
two were kept in two separate barns ; No. i contained seventeen 
head. No. 2 fifteen. The sanitary conditions were, however, 
quite different in the two cases. Barn No. i was so filthy that 
every time an animal moved the slush would ooze out from be¬ 
tween the boards of the floor, while barn No. 2 was well kept 
and comparatively quite clean. Of No. i, fifteen out of seven¬ 
teen reacted, or 88.2 per cent., while of No. 2, only ten out of
