REPORTS UPON - KOCIl’s ANTI-TUBERCULAR FLUID. 
265 
tubercle bacillus in the bronchial and lacteal secretions, the 
cattle received subcutaneous injections of o.i, 0.2, 0.3 ccm. of 
the lymph. On the day before the exhibition of the medium, 
the temperature was recorded every two hours-from eight 
o’clock in the morning to six in the evening. On the day of 
the injection, and also on the following days and nights, it was 
measured every hour. The symptoms displayed when the 
fluid was introduced into the consumptive cattle were de¬ 
veloped twelve hours later, and persisted for four; the temper¬ 
ature was notably increased. In some cases it reached io 7°F; 
the intensity of the reaction, as well as the length of the 
febrile period, depended upon the quantity of the liquid in¬ 
jected. 
The respiratory act was accelerated, and performed with 
more or less exertion ; the appetite was likewise disturbed. 
The fluid when injected into healthy animals produced no 
deviation from normal; the post mortem obduction of such 
animals was also negative. 
Gutman, who superintended the experiments, expressed 
his judgment of the results in the following words: “The 
X 
Koch lymph is an excellent diagnostic agent in tubercular 
cattle, and as such is of the greatest economic and veterinary 
importance.” 
These are the first official notices regarding the action of 
the medium upon tubercular animals of the bovine species. 
It is to be regretted that they were not issued from the land 
in which the celebrated discovery was made; it was not> 
however, for the want of suggestions in this direction. The 
trials will shortly be inaugurated upon an extensive scale in 
this country (Germany). 
GERMAN REPORT. 
The favorable results obtained in the human species by 
the use of the Koch fluid in the diagnosis of tuberculosis, has 
induced the Royal Board of Health to grant the Secretary of 
the Interior permission to try the worth of the agent upon 
tubercular cattle. The exceeding difficulty of an infallible 
diagnosis has always stood as an impediment to the perma-
