TUBERCULOSIS COXTROL. 



The following dairies were visited and cattle tested : 



1st to 3d — M. Gomes — 6 cows, all passed. 



1st to 3d — J. P. ]\Iendonca — 1 cow, passed. 



11th to 13th — Isenberg — 2 cows, passed. 



23d to 25th — Isenberg — 179 cows, 3 bulls : 163 passed, 19 con- 

 demned. 



26th to 29th— Isenberg— 134 cows, 4 bulls; 120 passed, 18 '.:on- 

 demned. 



All reactions were typical and unmistakable : all were well de- 

 fined and three were large enough to be easily seen across the 

 corral and were, in fact, the largest swellings which I have so 

 far observed. They were oval in shape and were, as near as one 

 could judge, li/^"x2" in size, firm to the touch but not hard, -md 

 exhibited no heat or pain, in fact, were typical reactions. 



It has been a disputed point as whether or not more time should 

 be allowed between the time of injection and the time of examina- 

 tion. The evidence gathered on this point during this last test 

 practically settles the question in favor of a period of 72 hours 

 elapsing before the examination is made. 



In the bunch of 138 head seventy-two hours were allowed to 

 elapse before an examination was made. On the forty-eighth 

 hour the foreman of the ranch made a very careful examination 

 and picked out fifteen reactors, the remaining ones, he declared, 

 gave no evidence of a swelling of any description. When I made 

 my examination, twenty-four hours later, I picked out eighteen 

 which gave typical reactions. His fifteen corresponded with fif- 

 teen which I had declared tuberculous and I had found three 

 more which he was emphatic in declaring had shown no indica- 

 tions of reacting on the forty-eighth hour. Thus the importance 

 of the extra twenty-four hours. 



Without doubt the majority of tuberculous animals can be 

 picked out at the end of forty-eight hours, but as has been demon- 

 strated there will be in some instances a few which will not show 

 the characteristic reaction until a later time which makes it a 

 necessity to wait seventy-two hours before making a final ex- 

 amination. By doing so nothing is lost and everything gained, a 

 reactor cannot become lost as the swelling remains five or six 

 days, but the entire test may be rendered useless if sufficient time 

 is not allowed for its proper working. 



GLANDERS. 



Glanders has again made its appearance in, to all intents and 

 purposes, an ownerless horse which had escaped from pasture and 

 brought to the Kalihi Pound. This animal gave typical symptoms 

 of glanders, there being a bilateral discharge from the nose, ulcers 

 on the nasal septum and swollen sul)-niaxillary glands.
