The forgoing disposes of many of the statements made on behalf of condensed skimmed milk, but, in view of the misleading comparison made between whole milk and one particn- cular brand of the condensed article, it is necessary to go further and point out that these statements appear to be based on the assumption that the milks are to be diluted to corre- spond approximately with fresh skimmel milk. The comparison mentioned above is useless, the product of such dilution would be too thick for infants.
Some of the brands on the local market have wrappers bearing directions in Chinese that the contents should be diluted 10 or 14 times with water.
The following Table shows partially the composition of some brands as sold and if diluted as recommended :—

In calculating the composition of diluted milk parts by measure have been taken as intended and the average specific gravity of condensed milks (130) has been employed.
The above Table should be compared with the following which sets forth the average composition of whole milk, and human milk, and also compares a whole milk with its machine-skimmed residue :-

To avoid friction the proposed wording of notice on label might be altered to "not suitable for feeding infants under one year".
I think it would be better if the new Section 28 gave the Governor-in-Council power to make regulations as to standards for all food products, and drugs also. There are other substances than those enumerated for which standards may become necessary, and the matter will be much simplified if the needful machinery is enacted now.
