General Conclusions. — It will be seen from the analysis of milk that the 
occurrence of tubercle in the milk obtained from the shippons in the city is diminishing. 
The presence of the bacillus tuberculosis in the railway-borne milk is, however, still 
too frequent, although there is no doubt that many of the milk dealers realize the 
importance, in their own interests, of banishing tubercle. 
Preserved Milks, Cheese, Butter, and Margarine 
Condensed Milks. — As in the previous year, the condensed tinned milks are not 
always found to be sterile, or free from organisms. This form of milk ought always 
to be sterile ; if it is not it has no advantage over raw milk, from a bacteriological 
point of view, and it may be the means of distributing pathogenic germs. 
Sterilized Milks. — The analyses have revealed the presence of bacteria. This 
is most unsatisfactory, and shows that sufficient care is not taken to sterilize the milk, 
and that the manufacturers do not employ proper means to ensure the efficacy of 
their sterilizing processes, nor do they adopt tests to prove that their methods are 
effectual. Unless milk sold as sterilized is actually so it has no advantage over non- 
sterilized milk ; on the contrary, the consumers are entirely misled, and an article is 
supplied which is not of the nature, substance, and quality demanded.
