ANSWERS TO QUERIES 



Names of Manufacturers. — We gladly 

 furnish our querists with information 

 concerning the manufacturers of goods 

 handled by the drug trade, but for ob- 

 vious reasons, such answers are not pub- 

 lished in this department. 



Dose of Methylene Blue. — R. G. F., 



New York, has had a prescription call- 

 ing for methylene blue capsules to be ad- 

 ministered in doses amounting to 30 

 grains daily. The question is whether 

 such dosage is safe. 



The dose is away beyond the average 

 dose given in the Pharmacopeia (23/I 

 grains) and reference to other works 

 (Merck's Index) brin^ out that the 

 maximum dose is 15 grains daily. For 

 this reason, we would hesitate about 

 dispensing the 30 grains daily dose and 

 would consult the prescriber about the 

 matter. 



Diluted Caustic Pencil.— M. C. D., 



New York. — Fused silver nitrate of the 

 Pharmacopeia is made by melting 100 

 grammes of silver nitrate to which 4 

 grammes of hydrochloric acid have been 

 added and then pouring the fused mass 

 into moulds. If you wish to make a 30 

 I.er cent, caustic point, try mixing 30 

 grammes of silver nitrate with 70 

 grammes of either potassium or sodium 

 nitrate, adding about 2 grammes of hy- 

 drochloric acid and then bringing the 

 mixture to a state or fusion.
