Arsenic in the animal body, W. H. Hloemkndal {Arch. Pharm., 2.'i6 (1908), 

 No. S. PI). .')!)!I-(HI)). — After adiniiiistratioiis of arsenic, post-iiKirteni examina- 

 tions revealed its presence in all parts of the animal body, its relative pi-edom- 

 inance beiiij; as follows: Nails, hair, s])loi'n, thyroid, skin, hmjis, liver, kidney, 

 heart, bones, nmscles, sex orjians, and Itrain. In the human body a larger por- 

 tion of the acid was excreted than in cows, goats, or rabbits. Rut little arsenic 

 was found in the milk of the c<iw or goat or in liunian milk and no traces were 

 found in the fetal circulation of young rabbits.

 upon milk production, A. Morgen, C. Begek, and F. Westhausser (Landic.

 p. 97.S), in which sheep and goats were fed a basal ration supplying on an aver- 

 age al)out 2.r> kg. i)rotein and 1 kg. fat per 1,000 kg. of live weight. At different 

 periods a portion of the protein, about 0!) kg. per day, was replaced by amids 

 and by carbohycb'ates. The princi]>al amid used was an extract from malt 

 sprouts. The results are suumiarized as follows:

The largest amount of milk and milk solids was obtained with the ])rotein 

 ration. Tlie amids of nialt-si)rout extract were much inferior in feeding value 

 to those of the plant extract. The different rations had but a trifling effect on 

 the quality of fat when tested with a refractometer. 



The protein was better digested when no amids nor carbohydrates were sub- 

 stituted. With aspai'agin as a substitute the quantity of fat was reduced. 

 During the amid period there was a larger amount of protein in the feces. The 

 authors consider that the anuds were changed into indigestible proteids and 

 tliat this transformation probably took place in the upper i)art of the small 

 intestine.
