with the explosive pressures. — M. Chelle : The trans- 

 formation of hydrocyanic acid into thiocyanic acid in 

 the course of cadaveric putrefactions ; experiments 

 made in vitro. In putrefactive phenomena hydrocyanic 

 acid is in part transformed into tliiocyanate. In some 

 experiments in vitro with Ivnown quantities of cyanide 

 added to normal blood, after ten days the hydrocyanic 

 acid had apparently disappeared, but could be almost 

 wholly recovered by oxidising the thiocyanate formed.
