POODS NUTRITION. 477 



of oatmeal porridge (made with water), a little butter and sugar. Wheu the diet 

 consisted of porridge made with milk, the following average coetlieients of iligesti- 

 bility were obtained: Dry matter, 92.49; nitrogen, 86.43; fat, 92.0, anci carbohj'- 

 drates, practically, 100. The comjiarative dige.'^tibility of oatmeal and other foods is 

 diK'ussed. According to the author, oatmeal and milk furnish the body with some- 

 what more energy than a like amount of bread and milk. This, however, is not 

 considered a sutticient basis for the extravagant statements made by manufacturers 

 coMcerning the nutritive value of such goods. 



Eggs in cold storage, M. Cooper (Chicago: H. S. Rirh <i- Co., 1S99, pp. 88, figs. 

 10). — The theory and practice in preserving e^s by refrigeration are discussed. 

 Much of the information given was received in answer to requests addressed to indi- 

 viiluals and comjjanies commercially interested in the subject of preserving eggs by 

 refrigeration. The author also reports the results of experiments on the effects of 

 low temperatures on eggs. 



The danger attending the increased consumption of sugar, G. von Bunge 

 {Ztxi-lir. liioL, ol {IHOI), Xn. J, pp. J55-P:!G). — In the author's ojiinion there is a pos- 

 sible danger in consuming considerable amounts of sugar, due to the fact that this 

 material is lacking in calcium and iron salts. These salts are present in honey and 

 sweet fruits and the author believes their use is not attended with harmful results. 

 A detailed ash analysis of honey is reported as well as estimations of the calcium and 

 iron in ligs, dried plums, ilates, fresh pears, and dried malaga grapes. 



Food and the principles of dietetics, R. Hutchinson ( London : Edward Arnold, 

 1901, pp. XVIII • '>48, col. pis. S, thj.'i. o4). — The general to\nc. of food, its composi- 

 tion and digestibility, theories of nutrition, etc., are treated of extensively. A note- 

 worthy feature of this volume is the large amount of analytical and other data regard- 

 ing jiatent and commercial foods and food products, a class of goods in regard to 

 which it is diflficult to secure reliable information. The volume is provided with a 

 fuHindex, and references are uniformly given for the large number of investigations 

 cited. 



Food supply [during the siege of Mafeking], R. S. S. B.\den-Powell {SoiUh 

 African Dispatches, Vol. I. London: JlarriHon & Sons, 1901, pp. 106, 107, 110). — A 

 detailed account is given of the food supply during the siege of Mafeking. The 

 foods consisted generally of canned meats, horse tiesh (largely used for making sau- 

 sages), l^read from ground oats, sowens (a form of porridge made from oat Ijran), and 

 fresh vegetables (largely grown within the defenses) , with some condiments. The 

 daily ration per man, at first, was made up of 1 lb. meat, 1 lb. bread, 1 lb. vegetables, 

 J oz. coffee, 5 oz. salt, 2 oz. sugar, and h oz. tea. Later in the siege the amounts were 

 reduced to f to 1 lb. meat, 5 oz. bread, 6 oz. vegetables, ^ oz. coffee, \ oz. salt, and 

 1 qt. sowens. [The first ration has been calculated to furnish 142 gm. protein and 

 2,.^00 calories; the latter, 149 gm. ])r()tein and 2,700 calories. — Ed.] 



The theory and practice of military hygiene, E. L. Munson {IXi'ir York:

 troops an<l the ration under different conditions of peace and war are treated (A at 

 length, as well as the numerous other topics pertaining to military hygiene. In every 

 case, in addition to original material, the author has given a careful summary of the 

 work of other investigators on the topic, and in this and other ways the work is a 

 very complete manual of the sul)ject treated. 



Food products: A manual for traders and others, C. J. Higginson {London:
