stitutes about one per cent, of Liebig's Extract. Doses of 

 one half to two decigrams of carnine, and its hydrochloride, 

 appear to have a slight effect on the nerves, a slackening of 

 pulsations being the most marked symptom. 21 A, August,

DIMINISHED FAVOR OF MEAT EXTRACTS. 



The favor with which the various forms of meat extracts 

 w r ere received some years ago is now diminishing, and it is 

 even stoutly maintained that they are inferior to the beef tea 

 prepared in the old-fashioned way. This result has been 

 caused by the fact that the meat extract has been found to 

 be composed almost exclusively of salts, and to be entirely 

 destitute of albumen, and even of the gelatine which is con- 

 tained in beef tea, causing it to coagulate w T hen cold. Al- 

 though the meat extracts are possessed of some valuable qual- 

 ities, they are now generally believed to be far from having 

 the virtues once ascribed to them. 20 A, Dec. 9, 1871,721. 



PROPER RATION OF FOOD. 



In a public lecture, delivered at the Medical School of 

 Paris, in regard to the quantity of food required to keep a 

 man in a vigorous and healthy state, Dr. See remarked that 

 the daily allowance for an adult might be enumerated as fol- 

 lows: 1540 grains of meat, 300 grains of salt fish, 11,550 grains 

 of bread, 770 grains of lard, and 770 grains of dried and com- 

 pressed vegetables; a total of about 15,000 grains of solid 

 food, containing 1350 grains of albuminous matter. Incident- 

 ally he observed that crust of bread contains just twice as 

 much nutrimental value as crumb, which has 44 per cent, of 

 water. The highly nutritive value of wine was specially al- 

 luded to, and illustrated by the fact that, in some districts of 

 France and Spain, men live on bread and wine only, for many 

 weeks together, in a healthy and vigorous state. 



BUTTERMILK FOR INFANTS. 



According to several recent authorities on the Continent, 

 buttermilk furnishes a very valuable nutriment to suckling 

 infants, especially if a little rice meal or wheat flour be beat- 

 en up in it. It is also stated that children fed with this sub- 

 stance are much less liable to the ordinary diseases of infan-
