Test. (See Illus. Diet.) T., Abba's, for Arsenic, 

 consists in allowing Penicillium brevicaule to act upon 

 the substance to be examined, and in the presence of 

 arsenic noting the garlic-like odor produced. From 

 0.005 to 0.002 mgm. of arsenic may thus be detected. 

 Urine should first be deodorized with animal charcoal. 

 Acetanilid. See Rudolf-Fischer, Schroder. Acetone. 

 See Gunning, Malerba, Oppenheimer. Agostini's 

 Reaction for Glucose. To five drops of the urine 

 add five drops of 0.5^ solution of gold chlorid and 

 three drops of 20% potassa solution, and heat gently. 



If glucose is present, a red color will be produced.

 T., Allen's (Charles W.) Iodin. See under 

 Pityriasis versicolor. Allen's Reaction for Vege- 

 table Fats. Shake together for one-half minute equal 

 volumes of fat and nitric acid of specific gravity 1. 4 and 

 then set aside for 15 minutes. The presence of vege- 

 table fats (cottonseed oil) will cause the formation of 

 a coffee-brown coloration. Aluminium. See Thbtard.

 between Quinolin and Pyridin Salts. The chloro- 

 platinates of the latter, when boiled with water, are 

 changed into insoluble double salts with the elimina- 

 tion of hydrogen chlorid, whereas the former remain in 

 solution. Andreasch's Reaction for Cystein. To 

 the hydrochloric acid solution add a few drops of dilute 

 ferric chlorid solution and then ammonia. The liquid 

 will become a dark purplish red. Anilin. See

 Method of Differentiating Human from Other 

 Blood. Modified Uhlenhuth's antiserum method. 

 Human blood-serum is injected into the peritoneal cav- 

 ity of rabbits in doses of 10 c.c. every 8 or 10 days. 

 After 6 injections, their blood is collected and preserved 

 on ice ; the serum is pipetted off after 24 hours. Some 

 rabbits, as control animals, are not injected. The 

 blood to be tested is, if dried, first dissolved, and then, 

 as is fluid blood, diluted with ordinary water and salt 

 solution. Several drops of the test serum are added 

 and the tubes placed at a temperature of 35 . 

 If the blood to be tested is human, a turbidity ap- 

 pears invariably; if not human, it remains clear. 

 T., Arata's, for Artificial Dyestuffs in Urine 

 depends upon the observation that these dyestuffs are 

 abstracted from the urine by means of wool. The 

 fiber is then subjected to special reactions. T., 

 Arloing and Courmont's. See under Tuberculosis. 

 Arnold's Reaction for Narcein. Upon heating the 

 substance containing narcein with concentrated sulfuric 

 acid and a trace of phenol a reddish coloration results. 

 Arsenic. See Abba, Reichardt, Schlickuvi, Schneider. 

 Aymonier's Reaction for a-Naphthol. The 15% 

 alcoholic solution of o-naphthol is colored violet upon 

 the addition of cane-sugar and mixing with 2 volumes 

 of sulfuric acid. Upon the addition of I drop of a mix- 

 ture of I part potassium bichromate, IO parts of water, 

 and I part concentrated nitric acid the same «-naphthol 

 solution yields a black precipitate. /J-naphthol does not 

 produce either of these reactions. Bach's Reagent 

 for Hydrogen Peroxid. This consists of two solu- 

 tions: (a) 0.03 potassium bichromate and 5 drops of 

 anilin in I liter of water ; (/') 5'/ oxalic acid solution. 

 Shake 5 c.c. of the solution to be tested with 5 c.c. of so- 

 lution a and I drop of solution b ; in the presence of 

 hydrogen peroxid a violet-red color results. Baeyer's 

 Reaction for Glucose. Indigo is formed on boiling 

 a glucose solution with orthonitrophenylpropiolic acid 

 and sodium carbonate. When the glucose is in excess, 

 this blue is converted into indigo white. B.'s Reac- 

 tion for Indol. A watery solution of indol to which 

 has been added two or three drops of fuming nitric 

 acid and then a »% solution of potassium nitrite (hop 

 by drop, yields a red liquid and then a red precipitate 

 of nitrosoindol nitrate, C ie H 13 (NO)N, 1 HN0 3 . Bar-
