 SOT Compt. Rend., 1.24 {1S97), Xo. 1, pp. 10-Jl).—T\n} authors report briefly the 

 results of 2 series of experiments in which the respiratory (piotient was determined

 United States Department of Agriculture {Science, o {1S'J7), No. 117, pp. 4!).:-49G). — 

 The article gives a very brief descrijjtion of a respiration calorimeter and experi- 

 ments made with it, wbich have been carried on at Wesleyan University in cooper- 

 ation with the Storrs Experiment Station and this Department.

 of metabolism from the standpoint of energy. 



The length of time -which milk remains in the stomach under various condi- 

 tions, E. W. Kaudnitz (Milch Ztg., J6 {1S97), Xo. G, p. S7).—k brief report of expe- 

 riments with cats.

Some additions to our vegetable dietary, F. Y. Covilt.e ( U. S. Dept. Agr. Year- 

 hook 1895, pp. 205-214, figs. 9). — The author describes in detail a number of plants 

 which might be profitably used as pot herbs, including charlock, Swiss chard, chicory, 

 winter cress, dock, kale, marsh marigold, mercury, black mustard, orach, pigweed, 

 pokeweed, pur8lane,winter purslane, spinach, and New Zealand spinach. The author 

 believes that a more extended use of these vegetables would prove of benefit. 



"The plants enumerated here do not by any means comprise all the species that 

 might be used as pot herbs, but they have been selected so as to suggest to i)eople in 

 every part of our country certain plants growing in their own region wbich are avail- 

 able for use in this manner. Doubtless others, particularly among our native plants, 

 such as tbc common nettle, milkweed, and the round-leafed mallow, commonly known 

 to children as 'cheeses,' will be found e(iually important."

 25 {1897), Xo. 5, p. 27).— A general article.
