Experiments show that cows may be dipped in the official hmc and 

 sulphur solution at a temperature of from 110°F. to 118°F. without 

 affecting the secretion of milk to any appreciable extent.

In view of the resistance exhibited by the caterpillars of the wax 

 moth [Galleria mellonclla] to the tubercle bacillus [R.A.E., B, viii, 

 86], experiments have been made with a view to ascertaining the 

 curative property of an extract made from the bodies of these larvae. 

 Guinea-pigs inoculated with this vaccine, and subsequently with 

 tubercle bacilh, did not contract the disease,, and the possibility of 

 treating tuberculosis by this means is admitted. The method employed 

 should directly affect the pathogenic agent by preventing the acqui- 

 sition of the acid-resistant character or by destrox'ing it should it have 

 already formed, rather than by attempting to neutralise the toxin 

 secreted by Koch's bacillus.

A filarial embryo has been isolated from the blood of a cow infected 

 with Trypanosoma guyanense in French Guiana. It has been 

 provisionally named Microfilaria guyanensis. Microfilariae are less 

 frequently met with in the blood of bovines than of equines.

The experiments described were made on canaries infected with 

 Plasmodiiim relictum. The birds received subcutaneous injections of 

 quinine daily for three weeks from the day of inoculation and then 

 every second day. The birds thus treated did not show parasites in 

 the peripheral blood, or if infected, the infection remained latent from 

 the onset. As soon as the treatment was stopped the imm.unity 

 ceased. 



As applied to man, those treated b}^ preventive quininisation are 

 only subject to latent infection, and are therefore less dangerous as 

 reservoirs than others presenting intense infection of the blood.
