4 PROCEEDINGS OF THE 



The President drew attention to a dried specimen of an Agaric, 

 which he exhibited, one of the species allied to Agaricus alkalina. 

 Here there were two stipes and two very nearly perfect pileii, the 

 latter being joined by a kind of natural soldering, so as to be very 

 firmly fixed together, and forming in reality one pileus like a figure 

 of 8. One of the stipes had given way from the ground, and had 

 probably been broken off by the superior strength and vigour of 

 growth of the other. This specimen, the President remarked, 

 seemed to explain the curious appearance, sometimes noticed in 

 Agarics, of a perfect specimen bearing in a reversed position the 

 pileus and part of the stipes of another, the broken stipes pointing 

 upwards. Here it might be supposed that when first growing there 

 had been something like the condition of the Agaric exhibited ; but 

 eventually one of the specimens gained such strength as to break the 

 weaker off and carry it into the reversed position alluded to. 



The President then stated that he had brought a series of plants 

 (which were upon the table), to illustrate the vegetation of the Coal 

 measures ; they consisted chiefly of Ferns, Palms and Cycads. He 

 drew attention to their method of growth, fructification and the 

 venation of their leaves, and remarked on the peculiarities of climate 

 they required. 



The Microscopical Section having had under examination slides of 

 Diatoms from Albury Heath, Chilworth, St. Leonard's Forest, and 

 Brockham, Dr. Bossey presented a list of the species named there- 

 from, according to Smith's ' Diatomacese.' 



IZth March, 1873. — Professor Rupert Jones, F.R.S., &c., gave an 

 exceedingly interesting lecture, profusely illustrated with diagrams, 

 on " Coal; its Origin, Place and Extent." 



^oth April, 1873. — Mr. Sydney Webb e.vhibited the following 

 Lepidoptera, hitherto unrecorded, all of which had been taken in the 

 Keigate district : — 



Cucullia charnomillw, W. V. Taken at gas ; Redhill. 



Spilonota siiffusaiia, Koll. Occasionally beaten from hedgerows ;
