 December 6th. 



Captain McDakin exhibited a collection of New Zealand 

 ferns lent for the occasion by Mrs. Tassell of St. Dunstan's, which 

 were very much admii-ed, alike for their beauty and manner of 

 mounting. Mr. Wetherelt shewed under the Microscope a 

 variety of spores in their cases of our own ferns. Mr. FuUagar 

 exhibited a small portion of living fresh water sponge, SpongUla 

 fluviatdis, under the microscope and with the assistance of a 

 well executed diagram explained the manner of the circulation 

 of the water tkrough the cavities thereof.
