The President referred to the death of Dr. Matthews — a Member 

 of the Council — which had recently occurred. He was with them at

 relatives, in which he invited the meeting to join. The resolution of 

 the Council was then adopted by the meeting.

 to embody several useful improvements upon those previously con- 

 structed upon that principle. The first of these consisted of a rack 

 and pinion applied to the arc inclining movement by means of 

 which the Microscope could be smoothly and readily placed at any 

 required inclination by turning the milled head instead of using

 responsible, was a modification of the mechanical stage applied in a

 He had repeatedly tried to impress upon opticians the importance of
