268 PROCEEDINGS OF THE SOCIETY. 



A letter was read from Mr. Shearsby, in which he said he had sent 

 to the Society a small bottle of diatoms gathered from the Yass River, in 

 Australia, and asked if anyone would tell him the names of the species 

 included. He further offered to collect more specimens, if desired, when 

 out on his geological excursions. 



Dr. Hebb intimated that any Fellow of the Society wishing to take 

 up the matter, or desiring to have any of the material, should communi- 

 cate with Mr. Parsons.

 six Microscopes, four of the six known species of fresh-water Medusa?, 

 and two of the hydroid polyps producing them, of which he gave a short
