A Note on the Nutritive Values of the Dietaries of Bengal Jails

scales of diets in use in the jails of the Province of Bengal, with the optional or permissive alterations sanctioned by the Jail Code. These scales of diet have been in force since the year 1881, and are reproduced with slight variations in the revised Jail Code. In all thirty-two variations of diet are here given, and their respective chemical values calculated both in terms of nitrogen and carbon, and in terms of the proximate aliments the food stuffs contain. As Professor Parkes has said, " the phenomena of nutrition are chiefly owing to the various chemical interchanges of nitrogen aud carbon," therefore the amounts of these two elements in
