Held on the 20th of Makch, lt)07, at 20 Hanover Square, W. 

 Dr. J. W. H. Eyre, Vice-President, in the Chair. 



The Minutes of the Meeting of the 2()th of February, 1907, were 

 read and confirmed, and were signed by the Cliairman. 



The following Donation to the Society was announced, and the 

 thanks of the Meeting were voted to the donor. 



From 

 A Solar Microscope by Nairne Mr. F. R, Tindall Lucas. 



In reference to the Old Solar Microscope presented to the Society by 

 Mr. F. R. T. Lucas, Mr. Rousselet mentioned that they had not hitherto 

 possessed any Microscope by the same maker — Nairne — and were there- 

 fore very pleased to add it to their collection. Unfortunately it was 

 incomplete. It probably dated from the beginning of the last century. 



Mr. Murray's paper on " Some South African Tardigrada," collected 

 by Mr. Milne of Uitenhage, was read by Mr. Rousselet, and was illus- 

 trated by plates of the species refeiTed to, and by specimens exhibited 

 under Microscopes in the room. 



Mr. Hardy's paper " On Myxomma tenue'^ was read by Dr. Hebb. 



Mr. C. L. Curties exhibited a new form of removable mechanical 

 stage giving a lateral movement of 2 in., which it was thought would 

 prove of advantage in cases where it was necessary to examine a long 

 smear of blood or other matter. The vertical movement of this stage 

 had the usual 1 in. movement. 



The Chairman thought this was a very useful form of mechanical 

 staffe, srivinji: an extensive horizontal movement, which was often 

 desirable in the examination of blood films. 



Mr. A. E. Hilton, who had arranged an exhibition of specimens 

 of British Mycetozoa under a number of Microscopes in the room, gave 

 an interesting account of the life-history of these organisms, illustrating 

 his remarks by drawings on the board. It was pointed out that, 

 although formerly classed amongst the Fungi, their life-cycle is 

 essentially different, for while in their sporangial stage they resemble 

 Fungi, in their subsequent amoeboid and plasmodial stages they are 

 quite distinct, the plasmodial being their reaUy distinctive stage, 

 differentiating them from all other groups.
