accomplislied by a slide. A glass tube, closed at the lower extremity 
by a piece of thin covering-glass, was attached to the mounting, and 
the tube of the microscope being placed inside this, the instrument 
could be efficiently used without any portion of it coming into con- 
tact with the water. It was announced that a class for the study of 
Biology would be commenced in October by Dr. Braithwaite ; and Mr. 
Suffolk intimated his willingness to repeat his course of lectures upon 
Microscopical Manipulation. The proceedings terminated with a con- 
versazione, at which many objects of interest were exhibited, amongst 
which some very beautifully executed coloured drawings of magnified 
insects by Mr. Eichter deservedly attracted much attention.
