NUTRIMENT. 



I 



IComparative quantity of nutriment in the various articles used for food among all 

 I nations ; derived from a report of Messrs. Perey and Vanquelin, and presented to 

 the French Minister of the Interior. 



I The result of the experiments of Messrs. Perey and Vanquelin 

 IS as follows : — In bread, every 100 lbs. are found to contain 

 30 lbs. of nutritious matter ; butchers' meat, averaging the various 

 sorts, 31 lbs. ; French beans, 80 lbs. ; pease, 23 lbs. ; lentiles, 94 

 lbs. ; greens and turnips, 8 lbs. ; carrots, 14 lbs ; potatoes, 25 lbs. 

 According to this estimate, 1 lb. of good bread is equal to 2 1-2 

 )r 3 lbs. of the best potatoes ; and 75 Ibs.^bread and 30 lbs. butch- 

 jfs' meat, are equal to 300 lbs. of potatoes ; or again, 1 lb. of rice 

 )r of broad beans, is equal to 3 lbs of potatoes, while 1 lb, pota- 

 •oes is equal to 4 lbs. of cabbage, and to 3 lbs. turnips. This 

 •calculation is considered perfectly correct, and may be useful to 

 "amilies, where the best mode of supporting nature should be 

 idopted at the least expense. 



1 One remark seems to be called for in connection with the 

 |bove extract, viz : That it is rarely, if ever, proper to 

 fring the condition of food into a concentrated state, so as to oc- 

 tupy the least possible bulk — or, in other words, to separate the 

 utritious from that which is not of this character. Some bulk is 

 bsolutely essential to health, and even to satisfy the cravings of 

 be appetite ; still, this comparative view of the different nutri- 

 lents, is highly important, and not only worthy the attention of 

 fiose who are charged with the duty of supplying food for fami- 

 es, but to those who feed stock ; and we have no doubt, but the
