Calories

Here a fair energy value is yielded by a large supply of 
fats and carbohydrates, while the proportion of proteids is un- 
usually low. 
The point of special interest in this diet is the very large 
amount of fat and carbohydrate food taken to get the necessary 
energy, an amount which many persons would find it difficult to 
digest. 
The cost of the week’s diet was 12s. 4d., or equivalent to 
14s. lOd. per man per week, or 25 J pence per day. The ordinary 
labourer’s family in Edinburgh gets a larger supply of proteid 
and a fair supply of energy for about 7d. per day. 
Study III. 
Along with a cutting concerning our Dietary Studies from the 
South-Eastern Advertiser of 24th February 1900, we received a 
letter from a Mr H., of which the following is an extract : — 
15 th October 1900. 
Dear Sir, — A fter reading the above, it occurred to me that I 
might as well send you a copy of my half-year’s expenditure. 
.... I cannot possibly be called a typical person ; but there 
are so few people who do keep exact records of what they eat, 
drink, and spend, that I suppose scientific men are glad to get 
such records from almost anybody.” 
With this letter was a very full and detailed budget of C. H.’s 
income and expenditure, and a detailed statement of the food 
consumed during the six months from 1st April to 30th September 
1900. It is unnecessary to publish this at length. The following 
list contains the articles of importance, and the quantity of each 
used, the quantities being expressed in kilogrammes : — Apples, 15*88 ; 
cherries, 0*45 ; bilberries, 0*45; strawberries, 0*45; melons, 8*00 ; 
red currants, TOO; gooseberries, 2*50; oranges, 20*00; lemons,
