The preceding analyses furnish unmistakable proofs of the 
fact that nine milk-men supplied the poor of the different courts 
and poor quarters of Strand districts with milk adulterated 
with 30 to 40 per cent, of water, and only one sold pure, 
genuine, and good milk. It further appears that only one 
of the samples from Camden Town and one from Kensington 
were genuine, and the rest more or less mixed with water. 
Notwithstanding the high per centage of cream (12 per 
cent.) in the genuine milk sold in the Strand district, the 
specific gravity of that milk was 1*030, and throughout the 
samples poorest in cream also had the lowest specific gravity. 
These facts afford a conclusive answer to the objection that 
no dependance can be placed on the gravity test. The fact 
■ss, cream, though lighter than skimmed milk, is denser than 
water, and any amount of water worth adding at all to milk 
can readily be ■ detected by the direct lowering of its normal 
specific gravity.
