submitted to culture under glass. Comparative 
studies of the same plants grown under glass and in 
the open air. Under glass the plant appears to be 
stabilised at an earlier stage of its growth. The 
organs of secretion are always more abundant in 
the plant under glass.—Henry Cardot and Henri 
Laugier: The adaptation, transmission of acquired 
characters, selection by vital concurrence in the

Asiatic Society of Bengal, April 4—M. A. Wali: 
Hinduism according to Muslim Sufis. Some Sufi 
scholars of India conclude that India, like other 
countries, has produced prophets and saints, and 
that the teachings of the Vedas and Upanishads

the genus Buluminus or Ena) and one race of 
Helicavion vesinaceus Heude are described as new.— 
B. Prasad: SBivalve molluscs. Six ‘species of 
Corbicula from W. Yunnan, a Unionid and a

prawn of the genus Caridina were collected. One 
of the crabs is a new species of Potamiscus, while 
another (Potamon atkinsonianum) is interesting as 
being a Himalayan form. The Caridina from Lake 
Tali is new and is remarkable on account of the 
secondary sexual characters of the male.
