gammarus from near Northenden, almost identical with each 
other ; the shell or scales of the marine animal being most 
transparent. A question was asked by Mr. Mosley, if any 
of the members had observed the effects of placing marine 
animals in fresh water; two of the gammari, born in sea 
water, were transferred to fresh water, and their liveliness as 
exhibited after four days of the change, was as great as in 
their native element. Members were requested to acquire 
information on the subject, and communicate the same, as it 
is rather an important matter to owners of marine aquaria 
living at a distance from the sea. 
Mr. Brothers exhibited the tongue of a cricket, circula- 
tion in the chara, &c. 
Mr. Dancer sent for exhibition a specimen of Topaz, with 
natural cavities containing fluid and gases, which on boiling 
present curious phenomena; also a box of objects, two 
microscopes, &c.
