March 19th, 1903. 

 Prof. Sydkey H. Vines, P.R.S., President, in the Chair. 

 The Minutes of the last Meeting were read and confirmed. 

 Mr. Joseph Burtt Davy was admitted a Fellow of the Society. 



Mr. Clement Reid exhibited drawings by Mrs. Reid of fruits 

 and seeds of British Preglacial and Interglacial plants (Thalami- 

 florae). In each case the specimens illustrated were the earliest 

 known representatives of the species. Most of the plants are 

 still living in Britain ; but among the Thalamiflorse from the 

 Cromer Forest-bed occur seeds of Hypecoum, a genus specially 

 characteristic of the Mediterranean region, and no longer found 

 living nearer than Southern France. The fossil seeds coi'respond 

 closely with the living Hypecoum penduhmi of Southern France, and 

 either belong to that species or to a closely-allied extinct form. 



The seeds of all the species of Hypecoum are covered by a curious 

 close mosaic of cubic crystals, apparently calcium oxalate, which 

 fill square pits in the surface of the testa. Traces of these pits are 

 still found on some of the fossil seeds. 



Mr. E. G, Baker, Dr. A. B. Rendle, and Prof. J. B. Farmer 

 joined in a discussion on the exhibition, and Mr. Reid replied.
