UssHER, appointed to explore Irish Caves. (Drawn up by the 
Chairman. ) 
Since our last report was submitted to the British Association, Mr. Ussher 
has completed the excavations of the extensive caves of Edenvale, co. 
Clare, and sent altogether a collection of more than 50,000 bones to be 
named. Besides these there were flints and implements used by primi- 
tive man and relics of various periods on which it is proposed to submit 
a detailed report to the Royal Irish Academy during next winter. 
Mr. Ussher has explored other districts of Ireland with the view to 
continuing the cave researches, but this Committee do not propose to 
apply for a further grant. 
The Edenvale remains have not been fully determined, but so far 
they have yielded the following species :— 
Man . E . (Homo sapiens) Arctic Lemming. (Dicrostonyx torqua- 
Bats . : . (Several species) tus)

The Influence of Salt and other Solutions on the Development of the 
Frog.—Report of the Committee, consisting of Professor W. F. R. 
WELDON (Chairman), Mr. J. W. JENKINSON (Secretary), and 
Professor 8. J. Hickson. (Drawn up by the Secretary.) 
Tue object of this investigation is to discover whether the distortion of 
development, or monstrosity, produced by growing the eggs of the frog in 
a certain concentration (about 0°6 per cent.) of common salt solution is 
due to the physical—increased osmotic pressure—or chemical properties 
of the solution, or both.
