 vomica and in Strychnos ignatius. It crystallizes in

Briicke's Berlin Blue Mass. A warm-flowing mass 

 for injecting tissues. It is made as follows : potassium 

 ferrocyanid, 217 gm.; water, 1000 c.c; ferrous chlorid 

 I part ; water 10 parts. Take equal volumes of these 

 solutions and add to each twice its volume of a cold 

 saturated solution of sodium sulphate. Add the iron 

 solution to the ferrocyanid solution, with constant 

 stirring. Filter and wash the precipitate with the 

 filtrate until it runs through clear, then wash with 

 water until the filtrate runs off blue. Dry the precip- 

 itate. To a concentrated solution of this blue add 

 enough gelatin to make a firm jelly when cold. Heat 

 to 6o° C. and filter through flannel. B.'s Fluid, 

 potassio-mercuric iodid, employed in the precipitation 

 of proteids. B.'s Method, a method of removing all 

 the proteids from a substance. Acidulate the liquid

 mercuric iodid, made by saturating with mercuric 

 iodid a boiling solution of potassium iodid. B.'s 

 Muscle. See Muscles, Table of. B.'s Reagent. 

 See Tests, Table of. B.'s Red Mass, a material for 

 injecting the body. A concentrated solution of potas- 

 sium ferrocyanid is injected into the artery until it 

 runs clear from the vein. Then as much as possible 

 is allowed to drain away. Next a concentrated solu- 

 tion of cupric sulphate free from iron is injected. By 

 this method the red cupric ferrocyanid is precipitated 

 in the vessels. B.'s Test. Same as B. 's Reagent.
