are in a sounder position, your Meetings have been made more inter- 

 esting, and in consequence have been better attended, also a larger 

 number of new Fellows has been elected; all this must surely be 

 taken as a sign that the Society has entered upon a new era of pros-

 during the past year have been numerous and of much interest. Two 

 Microscopes, one by Benj. Martin, presented by Dr. Dallinger, and 

 one by G. Adams, presented by Mr. J. M. Offord, are important, as 

 both are examples of high types of pre-achrotnatic instruments, and 

 in them we see some original devices still to be found in instruments 

 of the present day. 



A third Microscope, presented by Messrs. Watson and Son, repairs

 scope to be made by each of the three principal Microscope makers
