Preservation of Milk for Estimation of Fat. — 

 M. Weibull adds from 60 to 100 mgs. of potas- 

 sium permanganate to about 20 Cc. of milk 

 which will then keep for several months at 64 

 to 72° F. Sufficient permanganate is added to 

 produce a dark broMvn color, the milk being 

 shaken until il is completely dissolved; the 

 color disappears in a few days when more per- 

 manganate is added. Comparative analysis 

 with fresh milk and with milk kept 6 to 56 days, 

 gave results in which the greatest difference was 

 0.1 per cent, whilst in 8 out of 11 cases the 

 diflference was o 05 per cent, or less. — Exper. 

 Stat. Pec, 18^4, 536. 



Iron in Water. — A. Zega proposes the follow- 

 ing method for a colorimetric estuation of iron 

 in water. To 100 Cc. of the water (in which 

 the iron has already been oxidized to the 

 ferrric condition) i Cc. of nitric acid (Sp. Gr- 

 1.35 to 1.40) and 5 Cc. of a 5 per cent, solution 

 potassium thiocyauate are added. The colora- 

 tion develops rapidly and does not darken on 

 remaining. 100 Cc. of distilled water is then 

 similarly treated and a standardized solution of 

 a ferric salt containing o.oi mgm. of iron per 

 Cc. run in until the coloration produced is 

 equal to that in the water under examination. 

 The quantity of ferric solution added represents 

 of course, the quantity of iron in the water. In 

 this way 0.01 mgm. of iron per 100 Cc. of water 

 is easily estimated. — Chetn. Zeit., 1894. 1564. 



Cinnaviic Dichloride and Micro Orgatiisnis.— 

 A. Starenhagen and H. Finkenheimer in Ber. 

 d. Chem. ges., 1894, 456. Cinnamic dichloride 

 has been partially resolved by Liebermann and 

 Finkenheimer into its officially active com- 

 ponents. The present authors have treated 5 

 Gms. of the dichloride for four weeks with As- 

 pergillus fumigatus and isolated 1.5 Gms. of an 

 acid rotating [a]o = -|-i. From 6 Gms. of di- 

 chloride treated with yeast for three weeks, 2.2 

 Gms of an acid was obtained, giving [aj^ = 

 -\ 2.S. The organisms had multiplied during 

 the above periods, despite the formation of hy- 

 drogen chloride and chlorocinnamene. Blank 

 experiments (without the organisms showed 

 that while a small quantity of chlorocinnamene 

 was formed, the acid remained inactive.) 



Strychnos ignatia. — F. Ransonia, (British 

 Pharm. Conference), results show that although 

 the seeds of S. ignatia contain a larger proportion 

 of strychnine as compared with brucine, than 

 those of nux-vomica, the percentage of total 

 alkaloids is considerably less.

"94 COI,UMN." 



For the benefit of many of my fellow students 

 whom I dare say (like myself) have often been 

 asked the significance of the '94 class pin, I have 

 made a little investigation which netted me the 

 following: Caduceus in mythology, was the staff 

 with which Apollo used to drive the flocks of 

 King Admetus. He gave it to Mercury (called 

 Hermes by the Greeks) in exchange for the 

 Lyre. It thus became the attribute of Mer- 

 cury, and was his official satos or insignia of of- 

 fice, that of messenger of the Gods. Mercury, 

 by the way presided over orators, druggists, 

 tramps and thieves. 



The rod of Caduceus represents rectitude ac- 

 curacy and fidelity, the two serpents introducing 

 it to wisdom, the two wings despatch. Among 

 the Romans the Caduceus was probably an olive 

 branch carried by messengers and embassadors 

 as an emblem of peace. 



Dawson (262 Fifth ave. ). is as good a boy as 

 ever, the proximity of the celebrated tenderloin 

 district having not as yet affected him. 



Race (56th st. and Sixth ave.), is looking 

 greater and grander than ever, notwithstanding 

 the fact that he has been in commission since 

 commencement. 



Ex Secretary Linnig (498 Decatur st., 

 Brooklyn), is " punching pills " with his char- 

 acteristic vim in an atmosphere " cooled by 

 Ocean breezes." 



Col. Wade (86th st. and Park ave.). recently 

 returned from a short trip to his home in pict- 

 uresque Owego. This town proudly looks 

 upon him as one of her most clever bicyclists. 



The first customer one of our brilliant Ph. 

 G.'s was called to wait upon, meekly asked for 

 a bottle of ' ' cowsbath water. ' ' Upon receiving 

 the Sprudel she hastily left the store only to 

 return again shortly after for some Queen Anne 

 pills and "a teeth brush to clean her tooths" 

 as she expressed it. 



The Commercial Advertiser speaks of ex- 

 President Ehrgott as one of Jersey City's hand- 

 somest products. Last reports were to the ef- 

 fect that he is going to take an M. D. course. 



Nelson S. Kirk, 

 9 East 59th st. 



Dr. Henry D. Lovis, graduate of the class 

 of '90, an honor-roll and graduate of the College 

 of Physicians and Surgeons, class '93, has been 

 appointed Assistant Superintendent of the Sea- 

 bury Pharmaceutical Laboratories.
