licss were reported from their use The gradual reduction of this unlawful 

 adulteration to 7 per cent, In tin- face of protestations from tin- wholesale houses

The fate of boric acid In the body, E. Rost < Lrcft. Intcrnat. PharniaCod. ei 

 They., 15(1905); abs. in Brit. Med. -lour.. 1906, Vo. 1852, Epit., p. t6). The 



Investigations reported led to the c fusion that the kidneys are practically 



the only channels by which boric acid is eliminated, the quantity occurring In 

 the saliva, milk, and feces being very small. 



Of the total amount of boric acid administered. 50 per cent was eliminated in 



the urine in \'2 hours. Boric acid does not disappear from the body as rapidly 



as has been thought, since the remaining portion was not excreted for ■"> or I 

 days, and If boric acid be repeatedly taken, in the author's opinion, it may 

 accumulate in the body. 



The necessity for a national pure-food law, E. GntABD (Dietet. <m<l II tin. 

 Qae.,21 (1905), No. tl, pp.656 658). In connection with an address on the need 

 of ;i national pure food law delivered before the annual convention of the Intel- 

 national Stewards' Association, the author states that when pigs and Other 

 animals were given food artificially colored in the same way and to the same 

 extent as human foods they failed to make satisfactory gains in weight and 

 showed other unfavorable symptoms, whereas such was not the case with con- 

 trol animals fed food without artificial coloring matter and preservatives. Some 

 of the animals were shown. When the test was reported a pig receiving pure 

 food weighed L40 lbs. and an animal which had received the preservative and 

 coloring matter weighed only 85 lbs.
