ROYAI, ZOOI^QGICAI, SOCIETY. 



Recent gifts include freshwater iish from Major Gamble, a Silver 

 Pheasant from Mr. H. M. Smith, and a pair of White Herons from Dr. 

 C. B. Ball. Three Capybaras have been born in the gardens, a Lioness 

 has been obtained in exchange, while a kangaroo, seven Sheldrakes, ten 

 Puffins, and three gulls have been bought. 



Upwards of 20,800 persons visited the gardens during July. 



Dubinin Microscopical CIvUB. 



June 17.— The Club met at the house of Mr, F. W. MoORE, who 

 showed portion of the posterior sepal of Cirrhopetalum fimbriatum^ an 

 Indian epiphytal orchid. The edges are elegantly fimbriated, and it 

 was shown that these fimbriations were not mere trichomes or out- 

 growths of the epidermal cells, but that they were caused by irregular 

 growth of the tissues of the edges of the sepal. 



Mr. Greenwood Pim showed the aecidial stage of Puccinia graminis on 

 Barberry leaves collected at Avondale, Co. Wicklow. The uredo and 

 teleutospore forms of this fungus (wheat rust) are exceedingly common, 

 but the oecidiospores are much rarer, the Barberry on which'they occur 

 being far from common in Ireland. 



Mr. M'ArdIvE exhibited a proliferous form of Jungermania barbatay 

 Schmidel., which he collected recently on Brandon Mountain, Co. 

 Kerry. The specimens showed various stages of adventitious budding, 

 which first appears on the leaves ; a few cells are conspicuous by their 

 dark green colour. Closer examination shows them to be copiously 

 nucleated, and from rapid cell division a protuberance soon arises from 

 the tissue of the leaf which is but one cell thick. As growth continues
