Mr. K. J. Marks : Living specimens of Pedalion mirum, taken 

 in one of the ponds on Hampstead Heath. 



Mr. M. W. Liston : A thin portion of the secondary (green) 

 cortex of Rhaimius frangula (the berry -bearing alder), just below 

 the epidermis, showing " continuity of protoplasm " between the 

 cells, the walls of which have been dissolved away with sulphuric 

 acid. 



Mr. A. E. Hilton : A fresh-water alga, BatrachospermuTiv 

 vagitm, showing filaments with dense whorls of ramifying 

 branchlets — mounted in formalin. 



Mr. T. G. Kingsford : Portion of leaf of Sphagnum (bog moss), 

 showing large empty cells with spiral fibres and communicating 

 apertures. Stained. 



Mr. D. J. Scourfield : An *' Ephippium " of Daphnia magna. 

 The ephippium is a protective covering for the winter or resting 

 eggs, and is formed by a modification of the shell of the mother. 

 In all the true Daphnias there are two eggs in each ephippium 

 as in this case ; but in the closely allied genera, Ceriodaphnia, 

 Simocephalus and Scapholeb&ins, there is never more than one 

 egg in each ephippium. 



Mr. A. Merlin : " Madura Foot," a fungoid disease which 

 attacks the natives of India. 



September 20th, 1901. 



Mr. G. H. J. Rogers : A small colony of Cristatella mucedo 

 surrounding the stem of an aquatic plant. The reddish body 

 seen in the centre of the colony is probably a statoblast in an 

 early stage of development. 



Mr. T. A. O'Donohoe : One of the Poduridae, Seii^a buskii. 

 This species is easily recognised by its ovate or leaf -like scales, on 

 which the " notes of exclamation " are very long, extending 

 sometimes half the length of the scale. The scales are also 

 shown.
