    weekly, iu place of hroth. This rule, however, has not been enforced for some time, and no fish has been given during the course of my investigation. We are only concerned with the Diets No. 1 and No. 2 (non- working) ; and No. 1 and No. 2 + beef (working) ; and only slightly with the Infirm diet, which is No. 2, with beef tea ; and sweet milk for the buttermilk. Care has been taken to give the details of these diets with exactness. I shall now calculate from the same percentage figures, the quantities of proteids, fat and carbo-hydrates, contained in the lowest diet of Scottish prisoners. I find (l) that prisoners sentenced to more than 3 days and not exceeding 2 months (males) and 6 months (females)—have 2 ounces oatmeal more daily, but 2 ounces of bread, and ] pint buttermilk less, as compared with the pauper diet; (2) after 2 months (males) and 6 months (females) the diet is still upon the same lines, but the quantities are increased from 10 to 13 ounces oatmeal (paupers having only 8 ounces)—and the broth is increased from 1^ to 2 pints, the bread being now raised to 8 ounces ; (3) after a period of 6 months has been served, 14 ounces oatmeal and 12 ounces of bread are allowed jjer diem. All prisoners, after 4 months, get 12 ounces white fish, every Friday, instead of the broth. The broth also contains the meat used in the making, hence the higher value of the broth as compared with that of the pauper's diet. The most inter- esting for my purpose is to calculate the value of the 1st diet, viz. : the Scottish prisoner's lowest diet— working, but not heavy labour :— ^ „ f Pro- -ri .
