Report on the Microscopes and Cabinet of Objects. 



On no previous year have we had to report so favourably 

 as on the present ; it is, therefore, with much pleasure that 

 we present the following statement as to the number of 

 microscopes and objects the property of the Society. First, 

 as regards microscopes. 



No. 1. Wilson's Simple Microscope, with compound body, 

 several object-glasses, and various adjuncts. This micro- 

 scope is made of silver, and is of admirable workmanship. 



No. 2. Culpepper's Compound Microscope, with various 

 object-glasses and appliances. 



No. 3. Benjamin Martin's Compound Microscope, sup- 

 posed to be made for King George the Third. This in- 

 strument is a marvel ; and it is indeed a matter of surprise 

 to what perfection workmanship was carried in those days ; 

 the more it is looked into, the more is the spectator struck 

 with astonishment; and many things have since been 

 brought out as new which were made for this instrument. 

 There is a good description of it in our " Transactions," by 

 Mr. Williams, late Assistant Secretary, and also in Quekett's 

 third edition of ' The Microscope,' with a good engraving. 



No. 4. Powell and Lealand's best Compound Microscope, 

 made for the Society in 1841, with a full range of object- 

 glasses and every needful appliance ; this instrument has 

 lately had Mr. Wenham's Binocular arrangement added.
