greyish-white layer, with irregular soraewhat thickened margins. 

 Upon potato no development occurs, as a rule, at the room tem- 

 perature, but ill the incubator a thin yellowish, waxy layer is 

 developed in the course of a few days. Development in bouillon 

 (beef broth) is rapid and causes a uniform turbidity of the fluid. 



In concluding this paper I may state that as far as I am 

 aware there are no records to be found anywhere of any person 

 having previously discovered the existence of chicken cholera in 

 these colonies. I, therefore, claim priority in scientifically 

 proving the existence of this most interesting and historical dis- 

 ease in Australasia. Further, I have every reason to believe 

 that, from my own practical observations and the vast amount 

 of information I have received from reliable sources, it has 

 existed not only in Brisbane but in other parts of this and the 

 neighbouring colonies for a number of years. 



When we consider the extraordinary numbers of different 

 breeds of poultry which have been annually imported into 

 Australia from various European countries where chicken cholera 

 has been known to exist from time immemorial, and also the 

 numbers of live fowls (for table use) carried on passenger boats 

 to Australia from different English, American, and continental 

 ports, it appears more than ridiculous to suppose that a bacterial 

 disease like chicken cholera should have been excluded from our 

 shores up to the present time.
