colored powdery mass is obtained, which 

 only requires a little water to make into 

 a suitable pill mass. Two grains of mag- 

 nesium salt equal 3 grains of ammonium 



ichthyolate.

Despite several methods of manipula- 

 tion J. G. always obtained an unsightly 

 mixture containing a precipitate of fer- 

 ric hydroxide. He therefore wishes to 

 know how to obviate the difficulty. 



Compounding this prescription our- 

 selves we found that when a strictly 

 U. S. P. solution of ammonium acetate 

 was employed, that is, a solution that 

 was acid in reaction, a handsome red 

 liquor was obtained. In fact the blend- 

 ingr of the tincture of iron with the am- 

 monium acetate solution suggests the 

 similar blend occurring in Basham's 

 mixture even though the proportion of 

 the tincture to the solution is dififerent 

 than it is in the official preparation. So 

 our advice is simply : Be sure that your 

 solution of ammonium acetate is dis- 

 tinctly acid, 



VII. 



Potassium iodide 15.0 



Codeine sulphate 0.6 



Syrup of orange peel 45.0 

 Distilled water, enough to 



make 120.0 



Directions : Teaspoonful three times a 

 day, one hour after meals. 



In compounding this J. G. dissolved 



the alkaloidal salt and the potassium 

 iodide in separate portions of water and 

 then mixed the two solutions and finally 

 added the syrup. A fiocculent precipitate 

 occurred, which he was advised by an 

 older druggist to filter off. "Nothing but 

 potassium sulphate." J. G., however, 

 doubts the advice just given and turns 

 to us. Experiments show us that the 

 precipitate is codeine hydriodide, this 

 salt of codeine being much less soluble 

 than is the sulphate. The addition of 

 either sulphuric or phosphoric acid failed 

 to redissolve the precipitate, but we 

 found that the addition of 30 mils (c.c) 

 of alcohol in place of the same amount 

 of water resulted in the complete re- 

 dissolving of the precipitate. 



Of course, so radical a change in the 

 character of the prescription, the mak- 

 ing of a preparation containing almost 

 25 per cent, alcohol, should not be done 

 without first consulting the prescriber. 



Rongalite.— M. D., New York.— This 

 is a patented compound of formaldehyde 

 with sodium hydrosulphate, NaoSo04. 

 It is supposedly formaldehyde sulphoxy- 

 late. 



Legal Queries. — During the month, 

 we have answered a number of queries 

 relating to pharmacy laws, local, state, 

 and national, emphasizing each time that 

 the information given was merely the 

 personal opinion of a layman. For this 

 reason we do not print such answers, 

 since in serious legal matters a lawyer 

 should be consulted.
