CORPORATION BACTERIOLOGIST'S INVESTIGATIONS 85 
Milk. — The total number of samples analyzed has been 352. Of these 159 
have been taken at the railway stations on arrival from the country, and 162 from 
the town. 
Of the 159 railway samples, in 27 cases the inoculated animals died before the 
observation was completed, and of the remaining 132, 15 were proved to be 
tubercular, giving the percentage of tubercle in railway-borne milk as 1 1.3 per cent. 
Of the town milks, 23 inoculated animals died before the observation was 
completed ; of the remainder 1 was tubercular, thus giving a percentage of .7, or less 
than 1 per cent. 
There were 31 examinations of special samples of milk. None of these were 
tubercular. 
In the following table the + sign denoted the presence of tubercle, the — sign 
the absence of tubercle, and the word negative indicates that the animal died 
before the tubercular reaction had time to develop, if it were present in the milk 
which was inoculated.
