Gramonervin is the designation ap- 

 ])lied to tablets whose chief constitu- 

 ents consist of butyl-chloral-hydrate 

 and Calcium glycerophosphate, and 

 which are said to be of use in the treat- 

 ment of hay fever. 



Benzin-Substitutes. 



Owing to the scarcity and the pro- 

 hibitions against the sale of benzin on 

 the Continent, it has become necessary 

 to devise mixtures which might be em- 

 ])loyed in the place of benzin. Some 

 of such, proposed bv Dr. Karl Dieterich 

 of Helfenberg, are as follows : 



1. Benzolspirit. (a) 70 parts of 95% 

 denatured alcohol are mixed with 30 

 parts of benzol. It is recommended 

 that the benzol be added to the dena- 

 tured alcohol, slowly under constant 

 agitation. Admixture in reverse order 

 is to be avoided, (b) 50 parts ot go'/o 

 denatured alcohol, 20 parts of technical 

 acetone and 30 parts of benzol are 

 mixed in the following manner: Mix 

 the alcohol and acetone first and then 

 add the benzol gradually under con- 

 stant shaking. 



2. Benzinspirit. (a) 70 parts of 95% 

 denatured alcohol are mixed with 30 

 parts of benzin, the benzin being 

 poured into the alcohol, (b) 50 parts 

 of 90% denatured alcohol, 20 parts of 

 technical aceton and 30 parts of benzin 

 are mixed in the following manner : 

 Mix the alcohol with the aceton and 

 then gradually add the benzin. 



3. Spiritether. (a) 90 parts of 95% 

 denatured alcohol are mixed with 10 

 parts of sulphuric ether, (b) 90 parts 

 o^ 95% denatured alcohol are mixed 



with sulphuric ether 10 parts and naph- 

 thalin i part. The naphthalin is solu- 

 ble in the mixture if thoroughly agi- 

 tated. 



4. Acetonspirit. (a) 10 parts of de- 

 natured alcohol, 95%, are mixed with 

 30 parts of commercial aceton. (b) 50 

 parts of 90% denatured alcohol are 

 mixed with 50 parts of commercial 

 aceton. 



5. Petroleum mixtures. Petroleum 

 mixed with benzin or benzol in the pro- 

 portion of 2 to I, or petroleum 3 parts, 

 aceton i part, or petroleum 90 parts, 

 ether 10 parts and naphtlialin i part. 



Colorometric Estimation of Uric Acid. 



If uric acid is treated with a solution 

 of phosphomolybdic acid and di-sodic 

 phosphate, a blue coloration is noted. 

 The result is negative when applied to 

 albumen, peptone, albumenose, crea- 

 tinin, creatin, sugar, etc., unless a solu- 

 tion of sodium or potassium hydroxide 

 is used together with the solution of 

 phosphomolybdic acid. The blue color 

 produced as above with uric acid re- 

 mains permanent for several hours. 

 Riegler, in Phar. Zentr., 55, No. 34, 

 1914, describes a method for the esti- 

 mation of uric acid, based on the above 

 named reaction. The method is de- 

 scribed in detail and the needed appa- 

 ratus and solutions are enumerated 

 carefully. He also recommends that 

 albumin if present in urine be first re- 

 moved, and that any free acid lie 

 brought into solution Avith sodium 

 bicarbonate.
