ANSWERS TO QUERIES. 



Aristol.— K. C. D., New York.— This 

 is a synthetic chemical similar to dithy- 

 mol di-iodide of the Pharmacopceia. The 

 manufacturers claim some points of dif- 

 ference, which it is not necessary for us 

 to discuss. 



Official Saccharin. — S. L. M., New 

 York, desires to know if the tests for sac- 

 charin of the United States Pharmaco- 

 poeia provide for a product of the same 

 purity as that of the British Pharmaco- 

 poeia. This chemical called benzo-sul- 

 phinide in the U. S. P. and gluside in 

 the B. P. is given entirely different mon- 

 ographs in the two pharmacopoeias, the 

 tests of the U. S. P. being much more 

 elaborate than those of the English 

 standard. Both books agree that the 

 chemical should not yield more than 0.5 

 per cent, of ash and both provide that it 

 should not darken concentrated sulphuric 

 acid with which it is mixed. For other 

 comparisons, we suggest our querist con- 

 sult the two monographs from the phar- 

 macopoeias in our library. 



"Herba Herniosae."— T. K. Z., New 



Vork.^-While we find no reference to a 

 lierb of this name, we find a number of 

 articles describing herba herniariae, 

 which is the plant, Herniaria glabra, 

 which has been recommended for ca- 

 tarrh of the bladder. 



We are inclined to believe that this 

 drug was the one the prescriber had in 

 mind. •
