protein found in the blood, nor could it be shown that the composition of the 

 food protein, and particularly it glutaminic-acid content, had an effect on the 

 protein of plasma, or the proteids of the blood corpuscles. Cleavage products 

 of protein were not found in the Idood. (See E. S. R., IS, p. OT. ) 



Proof of the occurrence of dissolved proteid in adult feces, H. Schloess- 

 MANN {ZtsrJir. Klin. Med., 60 {1901), pp. 212-29},; c&s. in Chem. Abft., 1 {1901), 

 No. 6, p. 1-^2). — The proteid in feces extract which may be precipitated by acetic 

 acid consists principally of nucleo-proteid. Mucin, a substance of weakly reduc- 

 ing jiroperties, is generally present in fresh feces. The nucleo-proteid content 

 of adult feces is not changed by a diet rich in nuclelns. In the feces of children 

 such food results in an increased excretion of nucleo-proteid in the-feces. lender 

 pathological conditions there is generally aii increase in this constituent. With 

 the exception of the body under consideration no other proteid is found in feces 

 in health. The proteid which appears in the feces pathologically is, generally 

 speaking, albumin, though albumoses occur occasionally. 



Day and night urines, E. Osterdekg and C. G. L. Wolf (Jour. Biol. Chem., 

 3 {1901), No. 2, pp. 165-109). — Tiie analytical data reported do not show any 

 legulaiity in the volume of urine excreted, the excesses of excretion on each 

 diet being e(iually divided between night and morning urines. Furthermore, no 

 regularity was noted in the nitrogen or in the urea excreted. Except in one 

 instance with a low protein diet the ammonia excreted in the night urine was 

 greater than in the day urine. 



The authors believe that their results indicate an increase in the excretion 

 of creatinin in the day urine. " The amount is always higher during hours of 

 work. ... In each set the elimination of creatin was greater during the day 

 than at night. The uric acid appears to follow to some extent the course of 

 the creatinin. although during one period, the elimination is lower during a 

 waking period." 



The undetermined nitrogen of the urine was \A<th one exception greater during 

 the work ]>eriods. The elimination of sulphur showed more regularity than that 

 of nitrogen, the total sulphur, total sulphates, and neutral sulphur being uni- 

 formly higher during waking than during sleep. In the case of ethereal sulphur, 

 variations were noted, but they were not very large. 



The analysis of urine in a starving woman, F. G. Benedict and A. R. 

 DiEFENDOsF {Anicr. Jour. Pln/siol.. 7S (I'lOl), No. //, pp. 362-316). — The observa- 

 tions reported were made \\1th .-in insane woman who refused food. 



"The volume of urine of a fasting woman (without water) may be as low 

 as 237 cc. in 24 hours. . . . The nitrogen output during fasting increased for 

 the first 3 days and then decreased. On one day, at the conclusion of the fast, 

 the subject excreted but 3.17 gm. of nitrogen." 



The elimination of creatin, F. G. Benedict and V. C. Myers {Amer. Jour. 

 Physiol, 18 {1901), No. J,, pp. .',06-^2). — Studies with insane patients led to 

 the deduction that the experimental evidence at hand is as yet not sufficient 

 to show clearly the relation between creatin output and disease. The available 

 data would imply that creatin is excreted in wasting diseases where flesh is 

 broken down. 



The elimination of creatinin in women, F. G. Benedict and V. C. Myers 

 {Amer. Jour. I'hyniol., IS {1901), No. //. pp. 311-396). — The authors' summary 

 of the experimental data presented follows : 



" The creatinin excretion of women is, in general, much lower than that of 

 men. While the excretion is, in general, proportional to th^ body weight, this 

 is not always the case. Age appears to play an important role in the excretion 

 of creatinin. since elderly people excrete less creatinin than younger people, 

 with essentially the same body weight. The evidence furnished by the subject
