Royal Zoological Society.

 from Dr. H. O. Forbes, a Ring-necked Parrakeet from Mr. A. S. Belling- 

 ham, and a pair of Swans from Miss Cotton. Five Monkeys have been 

 purchased. 



12,600 persons visited the gardens during October. 



Dublin Microscopical Club. 

 May 18. — The Club met at Leinster House. 



Mr. Greenwood Pim showed specimens of Mycorrhiza from the roots 

 of Vaccinium and White Poplar. The mycelium on the first creeps over 

 the rootlets and in the second forms a kind of felted tissue, the root and 

 the fungus living and working together syinbiotically. 



Professor T. Johnson showed a preparation of the embyro-sac of an 

 angiosperm at the time of fertilization, and exhibited illustrations from 

 the Revue Generate de Botanique of M. Guignard's recent discovery of 

 antherozoid-like male generative nuclei and their functions in Lilium 

 Mart agon. 



Mr. G. H. Carpenter showed a female specimen of Cordylochete malteo- 

 lata (Sars.), a rare Arctic pantopod of remarkable form. The specimen 

 had been dredged in July, 1S98, by Mr. W. S. Bruce, of Edinburgh, when 

 cruising in the S.S. " Bleucathra " off the south-eastern coast of Spitz- 

 bergen. 



October 19. — The Club met at Leinster House. 



Mr. Greenwood Pim showed flowers of Ceropcgia Woodii, a curious 

 creeping or pendulous member of the Asctepiadacece The corolla is 

 tubular, swollen suddenly at the base, and divided above into four connate 

 segments, curiously bordered with hair. 



Mr. McArdlE exhibited Lejeunea Rossettiana, Massal., which he collected 

 last May on Ross Island, Killarney, to which district in Ireland it seems 

 now confined, though reported to have been gathered near Dublin by 

 Dr. Taylor in 1830. It is rare in England and also found in Italy. On 

 account of the hyaline papillose leaves it is a beautiful object. The 

 perianth capsule and spores were also shown ; from the membraneous 

 capsule a number of long cilia, angular at the apex, grow, extending past 

 the mouth, over which they curve in a remarkable manner and behave 

 exactly as do the teeth in the peristome of some mosses. A figure and 

 description will appear in the Irish Naturalist with Mr. McArdle's paper 

 on the Hepaticae of Ross Island.
