198 NOTES AND EXHIBITS. 



Dr. Katz also exhibited under the microscope the bacillus of 

 leprosy in a preparation derived from blood from a leprosy-tubercle 

 of a patient at Little Bay Hospital, and made the following remarks- 

 ^' This micro-organism is specific to leprosy in all its varieties ; it 

 must be looked upon as the cause of the disease, although very 

 little is known about its life-history. Cultivation experiments have, 

 so far as I am informed, totally failed ; nor have experiments on 

 the transmissibility of the microbe from tissues of lepers been 

 sufficiently successful. It is to be hoped that more information 

 about the Bacillus leprce will soon be forthcoming." 



The President exhibited a specimen of Archceocyathus sp., from 

 Silverdale, near Yass. 



Mr. Brazier exhibited two specimens of Geratella fusca, Gray, 

 obtained at Coogee Bay, March 7th, after an easterly gale, oae 

 specimen being of a very dark brown colour, and 3 inches long 

 the other of a light yellowish brown, 2^ inches long.
