Mr. Crisp exhibited and described Mr. Bulloch's new Objective 

 Attachment (p. 118), which he thought was more complicated than 

 was at all necessary, and which on that account could not be considered 

 an improvement on that of Mr. Nelson, or the Matthews- Watson form. 



Mr. John Mayall, jun., exhibited and described (1) Mr. Parsons' 

 Current Slide (p, 121), and (2) Nelson's Microscope Lamp, with the 

 oil vessel in the original square form (p. 125), and also with the im- 

 proved round vessel as suggested by himself. With the exception of 

 the very elaborate and expensive lamp devised by Mr, Dallinger, he 

 considered this to be the best lamp yet produced for microscopical 

 purposes. 



Mr. Crisp pointed out that the device made use of in Mr. Parsons' 

 slide was adopted by M, Nachet, some years ago, for adjusting the 

 depth of the cell in counting blood-corpuscles.
