SIR,—It is refreshing to read Mr. Cyril Ray's letter on

the need for penetrating the secrets of the wide- spread adulteration of our food.

Would you also add to the list of mysteries why milk vendors are allowed to sell for human con- sumption not only ordinary pure milk, but three other grades of increasingly inferior milk, the last ctf which is pasteurised. This fourth grade may have dirt and all kinds of disease germs in it, but is allowed to be sold because someone in the Govern- ment has the naive belief that it is quite all right to drink milk which contains sewage, provided it is cooked first!

Surely there should be only one grade of milk for human consumption—namely, milk!—Yours faithfully,
