568 EXPERIMENTAL RESEARCHES WITH CHICKEN-CHOLERA MICROBES, 



not dismembered, but they were pecked open, and their flesh and 

 entrails mostly missing. 



Experiments on Hares. 



Below are recorded a few experiments with the chicken-cholera 

 microbes on hares. "^ It will be seen that these rodents (which 

 were employed in full-grown specimens) are as easily amenable to 

 " chicken-cholera " as rabbits. 



1888. 

 (i) August 11th, 3.30 p.m. 



A hare was inoculated with five small platinum-loops full (about 

 l-40th ccm.) of virulent blood from a rabbit that had died after inocu- 

 lation with a small quantity of a virulent broth-culture of the microbe. 

 Control : — A control-rabbit (full-grown) was found dead at 9 a.m., 

 August 12th. P.M., Positive. 

 Result : 



The hare was found dead at 9 a.m., August 12th. P.M., Positive. 

 (ii) August 11th, 4 p.m. 



A hare was fed upon a few cabbage-leaves infected, by means of a 

 platinum-loop, with about j ccm. of blood from the same infected rabbit 

 from which blood was taken for the inoculation of a hare this date [vide 

 (i) above]. It was not until 10 p.m. {i.e., six hours after the infected 

 food had been placed in the box) that the hare was observed to have 

 eaten all the infected food given to it. 



Control : — A control-rabbit which had finished eating its portion of 

 infected food shortly after the food was placed in its box, was found 

 dead at 8.30 p.m., August 12th, having died between 5.30 p.m. and 

 that time {i.e., between 25| and 2S| hours after being fed). P.M., 

 Positive. 

 Residt : 



The hare was still alive at 11.30 a.m., August 16th {i.e., about 8 days 

 after the feeding referred to above). 

 (iii) August 16th, 11.30 a.m. 



(a) The same hare was fed upon cabbage-leaves infected with 1| ccm. 

 of a virulent broth-cultare of the microbe. 



• The hares used here were among five robust specimens received from 

 the country, through Mr. H. C. Taylor, Rabbit Branch, Lands Depart- 

 ment, Sydney.
