Aluminum sulphate loo parts 



Calcium carbonate 46 parts 



Diluted acetic acid (30%) 120 parts 

 Water enough 



Dissolve the aluminum sulphate in 270 

 parts of water, without the employment 

 of heat, then filter and dilute filtrate with 

 water until it has the specific gravity 

 1. 1 52. To this clear fluid, add calcium 

 carbonate rubbed to a paste with 60 

 parts of water. Then slowly add the 

 acetic acid, let the mixture remain in 

 an open vessel until no miore gas is 

 evolved, stirring from time to time 

 Finally decant the clear fluid from the 

 calcium sulphate precipitate, filter the 

 decanted liquid and dilute with water 

 to the specific gravity, 1.044 to 1.048. 



Compound Syrup of Cocillana. — J 



R. T., Illinois. — The only item we find in 

 the literature concerning this prescrip- 

 tion is a statement found in The Extra 

 Pharmacopeia that each fluid drachm 

 contains 5 minims of tincture cocillana, 

 15 minims of tincture of Euphorbia pilu- 

 lifera, 15 minims of syrup of wild lettuce. 

 3 minims of compound syrup of squill, i 

 grain of cascarin, 1-24 grain of heroin 

 hydrochloride and i-ioo grain of men- 

 thol. In passing it is interesting to note 

 that cocillana is one of the drugs intro- 

 duced into this country and Europe by 

 our own Dr. Rusby and that its botanical 

 name is Guarea Rusbyi. 



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. 



Syrupus Ferri Phosphatis Composi- 

 tus. — S. K. G., New York. — The name 

 just given is the title used in the British 

 Pharmaceutical Codex for the well- 

 known product, chemical food or Par- 

 rish's syrup. As the recipe given in the 

 Codex is dififerent from that of the Na- 

 tional Formulary, it is abstracted below : 

 Dissolve 0.43 gm. of iron wire in a mix- 

 ture of 5 mil of concentrated phos- 

 phoric acid and 3 mils of distilled water. 

 Cool the solution and add to it a mixture 

 of 1.36 gm. of precipitated calcium car- 

 bonate with .5 mils of phosphoric acid 

 and 10 mils of distilled water; then add 

 0.1 gm. of potassium, bicarbonate and 

 0.1 gm. of sodium phosphate, filter and 

 set aside. Next boil 0.34 gm. of cochi- 

 neal in 37.5 mils of distilled water, filter 

 and wash until 35 mils of filtrate are ob- 

 tained. In this filtrate dissolve 70 gm. 

 of sugar by aid of heat, strain and cool ; 

 then add the iron solution and 5 mils of 

 stronger orange flower water and lastly 

 enough distilled water to make 100 mils. 



For the purpose of comparison, we will 

 summarize the recipes of the third and 

 of the fourth (the new) editions of the 

 National Formulary. 



A''. F. Ill directs that 35 gm. of pre- 

 cipitated calcium carbonate be triturated 

 with 4 gm. of potassium bicarbonate and 

 4 gm. of sodium bicarbonate, with 82 

 gm. of citric acid, 375 mils of glycerin, 

 125 mils of orange flower water and with 

 70 gm. of phosphoric acid (85%) ; the 

 latter chemical being added gradually 

 and the mixture being stirred until solu- 

 tion is efifected. To this solution is add- 

 ed a solution of 17.5 gm. of soluble 

 ferric phosphate and 17.5 gm. of ammo- 

 nium phosphate in 250 mils of hot water. 

 Sugar is then dissolved in the mixed
