Tables VIII to XIII show that the condition of nutrition is 

 not an important factor in determining the nerve degeneration 

 and that a reasonable interval (two to forty-eight hours) be- 

 tween death and autopsy does not necessarily mean a sequential 

 myeline sheath change as demonstrated by the Marchi method. 

 (These bodies were kept at a temperature just above freezing.) 



The effect of decomposition on nerves was studied by the ap- 

 plication of the usual technic to pieces of tissue which have 

 been kept wrapped in muscle at room temperature and fixed at 

 varying intervals. Table XIV shows that degeneration either 

 persists or disappears as decomposition advances.
