anp Surface Marxines. By F. E. Wricur. Bull. Geol. Soc. 
-Am., vol. xxvi, pp. 255-86, 1915. 
N his work on the Obsidian Cliff spherulites, Iddings came to the 
conclusion that the expansion of liberated gases played little 
part in the development of lithophyse. The examples studied by 
Dr. Wright indicate, on the contrary, that the volatile components 
liberated with the radial crystallization of the spherulites ‘‘ aided 
materially in the original formation and subsequent enlargement of 
the lithophysal cavities’. Other structures are also discussed, notably 
surface pits and grooves etched by hot circulating solutions, which 
bear a striking resemblance to the surface markings of moldavites. 
While the terrestrial origin of the latter is not proved, it is shown 
that their external form and internal strains afford no evidence of an 
extra-terrestrial origin.

ANNUAL GENERAL MEETING. 
February 18, 1916.—Dr. A. Smith Woodward, F.R.S., President, in 
the Chair. 
The Reports of the Council and the Library Committee, proofs of 
which had been previously distributed to the Fellows, were read. 
It was stated that of the 31 Fellows elected in 1915 (6 less than in 
1914), 23 paid their Admission Fees before the end of that year, 
making, with 8 previously elected Fellows, a total accession of 31 in 
the course of 1915. During the same period, the losses by death, 
resignation, and removal amounted to 90 (34 more than in 1914), the 
actual decrease in the number of Fellows being, therefore 59 (as 
compared with a decrease of 11 in 1914). The total number of 
Fellows on December 31, 1915, was 1,250. 
The Balance-sheet for that year showed receipts to the amount of 
£2,836 2s. 10d. (excluding the balance of £105 18s. 5d. brought 
forward from 1914), and an expenditure of £2,306 7s. 11d. 
Reference was made to the fact that three out of the four members 
of the staff of permanent officers were still engaged in various duties 
under the War Office, and that temporary assistants had consequently 
been appointed. 
‘The decease of the former Assistant Librarian, Mr. William Rupert | 
Jones,! was announced, and the awards of the various Medals and 
Proceeds of Donation Funds? in the gifts of the Council were 
enumerated.
