independently, by three botanists, De Vries, Correns, and Tscher- 

 inak, in 1900. Details of some of Mendel's experiments were 

 given. The lecturer went on to demonstrate the relationship 

 between Mendelism and microscopical work, pointing out the 

 value of microscopical investigation in the ordinary experiments 

 with large organisms, and also suggested that many microscopic 

 creatures, such as the Entomostraca, would make excellent 

 subjects for experimental work. 



The Secretary announced that Mr. Rousselet had been elected 

 by the Committee to fill the vacancy in their list of Vice-Presidents 

 caused by the death of Mr. J. J. Vezey, F.R.M.S., and the 

 appointment was greeted with applause. 



At the meeting of the Club held on June 15th, Dr. E. J. Spitta, 

 F.R.A.S., F.R.M.S., President, in the Chair, the minutes of the 

 meeting held on May 18th were read and confirmed. 



Mr. E. R. Newmarch was balloted for and duly elected a 

 member of the Club. Dr. E. Penard, of Geneva, was also elected 

 an Honorary Member. 



Mr. J. T. Holder described an old microscope which had been 

 kindly sent for exhibition by Mr. W. R. Reeves, of Liverpool. It 

 was made by Andrew Pritchard, of Fleet Street, author of 

 The History of the Infusoria, etc., in 1846. Some six objectives 

 are provided, ranging from 2 in. to -^ in., and there are several 

 eye-pieces, one of which is provided with a micrometer. Lieber- 

 kuhn reflectors and polarising apparatus are fitted, and the stage 

 possesses a safety attachment, and has a mechanical movement 

 in one direction only. The coarse adjustment is so well made 

 that it is possible to focus the -| and ~s m - objectives by its aid 

 alone. Mr. Holder suggested that this is more than could be 

 said of the coarse adjustment of some modern stands. 



Mr. A. E. Hilton read a paper, "On the Study of the Myceto- 

 zoa." The life-history of a typical form was minutely described, 

 and illustrated by means of beautifully executed drawings. The 

 lecturer also gave a great deal of useful information of a practical 

 nature, and, in concluding, said that he hoped enough had been 

 said to show that the Mycetozoa, minute, mysterious, and 

 beautiful as they are, offer an attractive field for research, either 

 as a recreation or as a serious study.
