![of diet No. 1, as the value of the diet, with skimmed milk instead of buttermilk, would be, in calories, 2058*5, which is somewhat nearer the value, which I have already mentioned, as that required—upon the lowest estimate—for a man of about 9 st. 2 lbs. If 2058*5 calories be divided by 60 kilos, (about 9 st. 2 lbs.) the result shows the value to be equal to about 34^ calories per kilogramme of body-weight; and as 32 calories per kilogramme is admitted to be the very lowest necessary for a man in a state of absolute rest in bed, it may surely be acknow- ledged that this small increase of value is certainly not in excess of the requirements of paupers moving about freely and doing light work. The change would also allow of many of the inmates—at present on a bread and tea diet in consequence of their dislike to buttermilk—returning to the more nutritive porridge diets. No. 2 diet—the tea diet referred to—is not an official diet. It is simply the result of tea being allowed for porridge at night— as a favour. It is a diet of very low value, and should be con- demned as being not only deficient in nutritive value, but also lacking in the necessary quantity of iron requisite in every normal diet. The value of this diet (No, 2), if f pint of skimmed milk be substituted for the buttermilk, is : s Proteids. Fat. Carbo-hydrates. Nitrogen. Carbon. Grammes 74*8 17*9 333 = 13 189*1 which in total calories = 1838*3. As this, to a man of 9 st. 2 lbs., would only yield him 30| calories per kilogramme of weight, No. 2 diet is still far below a sufficiency; and if this form of diet is to be continued—as it must be, so long as tea is allowed —it should always be associated with some extra. No. 2 with beef is a working diet, the value of which, with the skimmed milk as above, would be 2198*5 calories. No. 1 with beef, and skimmed milk as above, would have the value of 2418*7 calories. The values of the four diets with buttermilk may now be compared with the values of the same diets when skimmed milk is given—in the same quantities :— Diets. With butter- milk. With skimmed milk.
