200 PROCEEDINGS OF THE 



at 7 o'clock, and the next Ordinary Meeting would be lield on 

 April 13tli at 7.30 p.m., when Mr. C. H. Cafiyn would give an 

 address on " The Microscopic Structure of Rocks." 



The President then called on Mr. A. E. Hilton to read his paper 

 on " A Log and Some Mycetozoa." 



Sir Nicolas Yermolofi said that the Mycetozoa were a startling 

 example of discontinuous variation. The spore when in suit- 

 able surroundings gives rise to a flagellate form, which passing 

 through the plasmodium stage reaches a more or less fungoid 

 condition. Energies in nature are continuous, but their mani- 

 festations are not always so. 



In answer to questions from various members, Mr. Hilton said 

 that he did not think light was a factor in the movements of 

 Plasmodia, but they might avoid a very strong light. He thought 

 Plasmodia would be likely to penetrate the wood rather than 

 remain on the surface, because the conditions were more favour- 

 able below the surface. He did not believe the plasmodium of 

 Lamproderma ever assumed an amoeboid form. The spores were 

 sown where the log was most damp and rotten. 



The meeting closed with a hearty vote of thanks to Mr. Hilton 

 for his interesting paper.

The Secretary announced that Mr. Rheinberg had presented a 

 copy of his paper {Trans, of the Optical Society) on Graticules to 

 the Club. 



A letter from the secretary of the Essex Field Club was read 

 enclosing a copy of a resolution that the Club had passed, and 

 asking if the Quekett Microscopical Club would take action on 

 similar lines. The resolution was as follows :
