Description:

‘Sir, - I was very sorry to read the article in your issue dated February 21 by “Medicus” on the question of Fish Meal for Dogs, and with the greatest possible respect for medical knowledge, I must in all fairness to the important industry which I represent, point out that he is not correct in what he says.

...

... if “Medicus” would read Bulletin No. 63, issued by the Ministry of Agriculture and Fisheries, he would see the wide difference between the two products [of white-fis meal and fish meal].

Breeders can be assured that white-fish meal is, without a single doubt, the finest protein food for dogs or cats, silver foxes, poultry, pigs, and every animal in the home or on the farm.

...

If any of your readers would care to have a copy of Bulletin No. 63, this will be supplied free on application to The Publicity Bureau, Association of Fish Meal Manufacturers, 148, Fleet Street, London, E.C. 4, who will also be glad to give any information regarding the qualities and use of this important product to anyone who may be interested.’
