the total nitrogen and nrea nitrogen of the urine. The nitrogen introduced in the 

 diphtheria virus is not sufficient to account for the excess. The change in the nitro- 

 gen content of the urine takes place very quickly. The animal organism takes an 

 active part in the formation of this serum, even if this is not shown hy fever or any 

 local reaction. The blood retains the antitoxic properties for only a short time after 

 the injections of diphtheria virus cease, and sometimes lose such properties even if 

 the injections are continued.

Zamia poisoning, A. W. V. Crawley (Producers' (laz. and Settlers' Bee. [ West. Aus-

 zamia poisoning in cattle. The symptoms of poisoning, post-mortem appearance, 

 and methods of treatment are given in some detail. According to the author, zamia 

 acts as a cumulative poisou, and cattle were probably encouraged to eat it on 

 account of other feed being scanty and dry. Attempts are being made to ascertain 

 the active principle or alkaloid causing the poisoning, and it is suggested that if pos- 

 sible all such plants should be eradicated from pastures.
