The usual nutrient gelatine (containing beef-infusion), as well 

 as such gelatine with 2 p.c. grape sugar, or nutrient gelatine con- 

 taining 2-7 p.c. sodium chloride, were occasionally taken into use. 



In order to avoid repetitions, I will mention here that all the 

 rabbits, upon which the microbes were tried from different points 

 of view, were wild rabbits, if not specially noted to the contrary. 

 These wild rabbits were ordered by the Kabbit Branch, Lands 

 Department, Sydney, from near Hay, in New South Wales, about 

 420 miles from Sydney ; they were mostly caught and sent to 

 Rodd Island in a large number of consignments from Carrathool,

I ascertained the weight of six full-grown, perfectly healthy wild 

 rabbits from Carrathool; the average weight was 1522 grammes 

 (3 lbs. 5f oz.).^ 



Effect of Chicken-cholera Microbes on Rabbits. 



It has been made known by Pasteur and others that rabbits 

 manifest a great susceptibility towards the microbes of chicken- 

 cholera, let the latter be applied as subcutaneous or cutaneous 

 inoculation, through the alimentary canal, by way of injection 

 into the peritoneal cavity, or of inhalation into the lungs. It has 

 also been shown that the mucous surface of the uterus, after par- 

 turition, can form a means of entrance for the microbes, when
