Mr. Ingpen exhibited and described a very beautif nl reflecting microscope 

 by Amici, which had been lent by Mr. Curties for that purpose. It 

 outwardly resembled one he had the pleasure of describing at a former 

 meeting, but was totally different in its principle, which was the same as 

 that of the Newtonian telescojoe ; the object being reflected by a small 

 diagonal plane mirror into a concave speculum forming an image which 

 was viewed by an eyepiece in the usual manner. These microscopes, or, as 

 they were then called, engiscopes, were made at a time when it was 

 doubtful whether achromatics could be improved. The definition of the 

 instrument exhibited was extremely good, the workmanship of the stand 

 excellent, and the ingenuity displayed in the various pieces of apparatus 

 attached to it was very great. This instrument was made by -Amici for the 

 late Dr. Roget, and was employed by him in his well-known researches. 

 Its date was probably about 1830. 



In answer to a question by Dr. Matthews, Mr. Ingpen said he considered 

 that the loss of light in such an instrument would probably be about 30 per 

 cent. 



The President announced that the Committee had nominated Mr. F. 

 Kitton, of Norwich, for election as an honorary member of the Club.
