Proceedings. 37 



[Microscopical and Natural History Section.] 



Ordinary Meeting, December 16th, 1895. 



John Boyd, Esq., President of the Section, in the Chair. 



Mr. Stirrup exhibited specimens of kelp from Tory 

 and Arran Islands, off the West Coast of Ireland. 



Mr. Melvill read a paper on " The Distribution of 

 Simethis bicolor (Kunth)," and exhibited specimens from 

 Branksome, Dorset. 



Ordinary Meeting, January 7th, 1896. 

 Henry Wilde, F.R.S., President, in the Chair. 



The thanks of the members were voted to the donors 

 of the books upon the table. 



Dr. C. H. Lees exhibited, on behalf of Dr. A. 

 Schuster, F.R.S., some photographs obtained by 

 Professor Rontgen, of Wiirzburg, by means of radiations 

 of an apparently new kind. These radiations are pro- 

 duced in Crookes' vacuum tubes, and pass readily 

 through paper, wood, and flesh, less readily through 

 glass, crystals, and thin films of metal, and are absorbed 

 by thicker films of metal and by bone. As far as 

 Rontgen's experiments go, these rays are neither reflected 

 nor refracted, nor has a double refracting medium any 

 apparent effect in polarising them. 



Mr. J. C. Melvill, M.A., F.L.S., read a paper 

 entitled " Notes on the British Distribution of Simethis 

 bicolor (Kunth)," a wild member of the lily tribe only 

 found in the neighbourhood of Bournemouth and in one 

 station in Ireland, as regards the United Kingdom, 

 though having a wide range through Western Europe. 

 Mr. Melvill's opinion is, however, that it is, nevertheless, 

 indigenous to the British Isles.
