76 OTHER ANTLIN STAINS. 



128. Violet B (S. MAYER, Sitzb. d. k. k. Akad. d. Wiss , Wien, iii Abth., 

 February, 1882). Used in solutions of 1 grm. of the colour to 300 grms. of 

 0'5 per cent, salt solution, and with fresh tissues that have not been treated 

 with any reagent whatever, this colour gives a stain so selective of the ele- 

 ments of the vascular system that favorable objects, such as serous mem- 

 branes, appear as if injected. The preparations do not keep well ; acetate of 

 potash is the least unsatisfactory medium for mounting them in. 



129. Anilin Black (Blue-Black, Nigranilin, Noir de Colin). Has 

 a special affinity for ganglion-cells, and is much used in the study of the cen- 

 tral nervous system (see post, Part II).
