to salts. His evidence is under five heads : 1. Leucocytes, which are very rich 

 in nuclein, show a strong affinity for metals. '2. In young dogs the endothelial 

 cells contain granulations shown by Kowalewsky to present the characters of 

 nuclear granulations. Organs of these young dogs absorb more mercury by 

 weight than those of older dogs in which the granules are absent. 3. It has 

 been shown that the amount of nuclein in an organ depends on the number of 

 cell nuclei present, and the author's experiments show that the amount of mer- 

 cury absorbed depends on the amount of nuclein present. 4. The non-nucle- 

 ated red-blood corpuscles of mammals are the only cellular elements that do not 

 absorb mercury. 5. An intravenous injection of methyl-violet reduces the absorp- 

 tion of mercury by the cells of the vascular endothelium. With this may be 

 compared the fact that cells treated with such substances as osmic acid do not 

 stain. The affinity of the nucleus for basic stains is itself a proof of the 

 author's view. a. m. c.
