In regard to this article it may be noted that most of the cities 
and larger towns of Canada undertake the local inspection of their own 
milk supplies. The work of the Inland Revenue has therefore been 
mainly performed with a view to the determination of practicable con- 
stants by means of which milk might be legally defined. A résumé of 
the work of the Department in this regard is published in Bulletin No. 
142 (Sept. 1907) and standards for milk, and the chief products of 
milk, were legalized by an Order in Council bearing date 3rd Nov. 1910. 
As a further help in ascertaining the influence of systematic in- 
spection upon our markets, we may take the case of Coffee. The 
following table is a condensation from the published work of the 
Department of Inland Revenue. 
Spices have been notoriously the most grossly adulterated food 
articles on the market. The following synopsis gives an account of 
their inspection since 1877; and it will be observed that only within the 
last two or three years have pure spices predominated.
