2, 4- and 2, 5-tolylene diamines were acetylated, 

 the acetyl derivatives oxidized to the correspond- 

 ing diacetamino benzoic acids, and the latter con- 

 verted into the acetamino acetanthranils by boil- 

 ing acetic anhydride. By condensing these acet- 

 amino acetanthranils with primary amines, and 

 other primary amino compounds, acetaminoquin- 

 azolines were obtained, from which the acetyl 

 group was easily removed, leaving amino quin- 

 azolines whose amino groups were then subjected 

 to various well-known aniline reactions. 



The Preparation of Styrolene Alcohol: Wm. Lloyd 



Evans and Lou Helen Moeqan. 



Styrolene diaoetate can be prepared quantita- 

 tively by the interaction of fused lead acetate 

 (1.5 mols.) and styrolene diacetate (1 mol.) dis- 

 solved in glacial acetic acid (six times the weight 

 of the dibromide used). The reaction begins at 

 120° and is practically complete at 125°. Styro- 

 lene alcohol can be prepared by the hydrolysis of 

 styrolene diacetate (1 mol.) by means of potas- 

 sium carbonate (1.5 mols.) dissolved in water 

 (twenty-five times the weight of the diacetate 

 used), the solution being kept to boiling for two 

 hours. From the cooled reaction mixture, subse- 

 quently saturated with potassium carbonate, the 

 greater portion of the alcohol may be precipitated, 

 the remainder being obtained from the filtrate by 

 extracting with ether. Oxidation experiments are 

 now in progress on styrolene alcohol and also on 

 propylene glycol. 



The Glycogen Content of Beef Flesh: P. F. Tbow- 



BEIDGE and C. K. Fbancis. 



The experiment in enzymatic hydrolysis has 

 been continued on similar lines to those reported 

 in the previous paper, working on the liver of 

 beef animals instead of the shoulder muscle. At 

 temperature of 20° to 25° a liver, containing 3.15 

 per cent, glycogen when exposed for about three 

 days contains about 2 per cent, of glycogen. 



Various authorities state that horse flesh con- 

 tains from 1 to 2.4 per cent, glycogen and it is 

 claimed the muscle of the ordinary horse has as 

 much glycogen as the liver. Our investigations 

 have not confirmed this assertion. Working on a 

 sample of fresh horse flesh obtained from a thin 

 animal about twenty years old, we have obtained 

 only 0.18 per cent, glycogen in the muscle. In 

 twenty-one hours this amount was decreased 67.3 

 per cent., while in three days the loss was 91.1 

 per cent., accompanied with a slight decomposition 

 of the sample. In the fresh shoulder muscle of 

 beef we have found as high as 0.7 per cent, of 



glycogen as previously reported. According to 

 these results the determinations of the glycogen 

 as distinguishing horse flesh from beef is of no 

 value.
