FOODS ANIMAL PRODUCTION. 275 



Analysis of the velvet bean (fruit), A. A. Persons (Florida Sta. Rpt. 1896, p. 65).— 

 The author reports the analysis of the fruit of the velvet Dean (Dolichos multiflorus) 

 as follows : Water, 11.93 per cent; protein, 18.81 per cent; fat, 6.29 per cent; nitro- 

 gen-free extract, 53.50 per cent ; fiber, 7.45 per cent; albuminoid nitrogen 2.-87 per 

 cent; and ash, 2.02 per cent. 



Prickly pears as fodder, W. J. Boyce (Agr. Gaz. New South Wales, S (1897), No. 4, 

 pp. 260, 261).— The prickly pear (whole plant) when cooked by steaming in a large 

 covered boiler containing a small amount of water was found to l>e a satisfactory 

 food for cattle. It was also relished by pigs. Th<- prickly pear has proved particu- 

 larly useful as a food stuff in certain regions of Australia in time of drought. 



The value of beet molasses and molasses peat as cattle foods, K. Wahlquist 

 (Rpt. rituna Agr. Inst. 1895, pp. 53-65). — Feeding experiment with 12 cows are reported. 

 As much as 1 kg. per head per day of molasses peat produced no ill effects on the cows. 



Feeding experiments with molasses feed, F. Funs (Landmansblade, 29 (1896), 

 pp. 647, 648). — This is a preliminary report of feediug experiments with cows and pigs 

 conducted at the Danish State Experiment Station at Copenhagen. The feed (■£• palm 

 nut meal, § wheat bran, i beet molasses) proved, in general, equally valuable, pound 

 for pound, as grain feeds. No deleterious results were noticed in case of milch cows, 

 even when 4 to 5 lbs. of molasses feed was fed per day. 



The influence of increased atmospheric pressure on the metabolism and 

 assimilation of nitrogen, N. A. Schmitz (O vliyanii szhatagho tozdukha na obmyen 

 azota i wvoenie azotistnikh reshchestv pishchi. Inaug. Diss. St. Petersburg, 1895, pp. 40, 

 dgm.l). — Observations were made with 4 subjects, a man and 3 boys. 



On the influence of the oxygen content of the air on metabolism, P. VON 

 Terra Y (Arch, gesam. Physiol. [Pjt tiger], 65 (1S97), No. 7-8, pp. 398-446, fig. 1).— The 

 author made a number of experiments with a rabbit and a dog on the effect of varia- 

 tions in oxygen content of the air on metabolism. A small respiration apparatus 

 was used. 



The influence of milk sugar on the metabolism of protein and on intestinal 

 putrefaction in healthy persons, LP. Solukiia ( K voprosu o vliyanii molochnago 

 sakhara na obmyen byelkov i kishechnoe thienie u zdorovbikh lyudet. Inaug. Diss. St. 

 Petersburg, 1896, pp. 90).— Ten experiments are described. The subjects were healthy 

 young men. Each experiment was divided into 2 periods. The food was the same 

 in both periods, except that during the second period 75 gm. of milk sugar was 

 taken daily in addition The nitrogen of the food and excretory products was 

 determined. 



Metabolism of nitrogen in healthy subjects when consuming milk charged 

 with carbon dioxid and when consuming normal milk, I. L. Kabakov (Ob 

 azotistom obmyenye tt zdorovnikh lyudei pri it pot reb yen it gazirovannago moloka v arav- 

 neniis prostnim. Inaug. Diss. St. Petersburg, 1895, pp. 50). — Six experiments were 

 made with men 24 to 29 years of age. 



The formation of fat in the animal body, S. Soskin (Jour. Roy. Agr. Soc. Eng- 

 land, 3. %er., 8 (1897), II, No. 30, pp. 355-367).— Reprinted from E. S. R., 8, p. 179. 



The excretion of phosphorus in metabolism experiments when casein was 

 consumed, G. Marcuse (Areh. gesam. Physiol. [Pfliiger~\, 67 (1897), No. 7-8, pp. 373- 

 394). — In connection with the experiments with a dog on the comparative digesti- 

 bility of casein and meat previously reported (E. S. R., 8, p. 513), the author also 

 studied the excretion of phosphorus. The phosphorus in food, urine, and feces was 

 determined. The principal conclusions reached was that when casein was fed the 

 phosphorus was apparently better assimilated than on a diet of meat. The experi- 

 ments are to be continued. 



On the diurnal variation of nitrogen excretion by man, R. Rosemann (Arch. 



gesam. Physiol. [Pfliiger'], 65 (1897), No. 7-S,pp. 343-392, dgm. 1).— The author made 



a number of experiments, of which he himself was the subject, to study the diurnal 



variation in the excretion of nitrogen in the urine. The urine was collected night
