A Letter was read from Captain Andersen, of the Cunard 
steamer Canada , from Liverpool to New York, accompanying 
specimens of the soundings taken during his last voyage across 
the Atlantic. Captain Andersen was kind enough to send 
the soundings by post from Queenstown, by which means 
they arrived just before the meeting. 
Mr. W. H. Heys, of Hazel Grove, exhibited his newly 
invented Kaloscope, by means of which he obtains refracted 
and reflected light of different colours at the same time upon 
objects under the microscope, producing beautiful effects in 
some cases.
