290 EXPEEIMENT STATIOlsr RECORD. 



copy of the proclamation of the board of live stock commissioners of 

 Illinois regardino- the importation of Southern cattle. In their experi- 

 ments with dips for the purpose of destroying the cattle tick on ani- 

 mals imported from the South some losses were experienced, but it is 

 believed that such losses are due not so much to the dipping itself as 

 to the fact that the dipping occurred at an inopportune time, or that the 

 cattle were subjected to fatiguing drives or railroad journeys after the 

 dipping. Detailed records are given of the inspection for actinomy- 

 cosis at the Union Stock Yards of Chicago. 



Special attention has been given by the board for a number of years 

 to tuberculosis among dairy cattle. The regulations of the board pro- 

 vide that animals condemned and slaughtered after the tuberculin 

 test shall be divided into 6 classes, for the purpose of adjusting the 

 amount of indemnity to be paid the owner. Class A includes animals 

 which upon jfosf-uio/'f em examination fail to disclose the presence of 

 tuberculosis in an}' of their organs. For such animals the full valua- 

 tion is paid as indemnity to the owner. The other classes are graded 

 according to the more or less generalized condition of the tubercular 

 infection, 75, 50, 35, 25, and 15 per cent of the appraisement being- 

 paid for animals in these classes. The number of animals tested was 

 3, (355, and of this number 560 reacted suHicientl}- to av arrant condemn- 

 ing, while 47 were isolated and held for a second test. The percent- 

 age of condemned animals was, therefore, 15.32. 



The board made an investigation of the milk of a number of tul)er- 

 culous animals, the milk being used for inoculating the experimental 

 animals, and ])eing also subjected to microscopical examination. The 

 conclusions which are drawn from these examinations ma}' be stated 

 as follows: The tubercle bacillus is found in the milk of 35 percent of 

 tuberculous cows with sound udders. The tubercle bacillus is found 

 with about equal frequency in the sediment and in the cream. The 

 milk when concentrated produces tuberculosis in about 25 per cent of 

 the inoculated guinea pigs. In a large number of cases pus cells were 

 found in the milk, which would indicate that the udder was aflfected 

 by tuberculosis. It is stated that in consideration of the greater sus- 

 ceptibility of the guinea pig. the concentration of the milk, and the 

 fact that inoculations were made hypodermically, allowance must be 

 made for the different conditions when these results are applied to the 

 human subject. 



Detailed notes are given on the occurrence in the State of glanders, 

 cerebro-spinal meningitis of horses, and sheep scab. In an appendix 

 to the report is found a complete record of the tuberculin tests already 

 referred to.
