268 PROCEEDINGS OF SOCIETIES. 
due, in part, to the fact that these old lavas had undergone a great 
change since their first formation; in fact they were really meta- 
morphic in a very legitimate sense ‘of the term. Mr. Ward’s paper 
showed that originally they were in composition very much the same 
as some modern lavas. Mr. Ward had worked out the subject in a 
most admirable manner, and the results of his investigations would 
be found to be set out in his paper in a very complete and satisfactory 
way. He thought the Fellows might congratulate themselves in having 
such a subject, so ably treated, in the course of their transactions. 
A vote of thanks to Mr. Ward was then unanimously carried, and 
the meeting was adjourned to May 2.

Scientific Evening of the Royal Microscopical Society. 
A scientific evening was held at King’s College on Wednesday, 
April 18, of which a detailed account, too late for the present number, 
will be given in the next one. We may mention that the upper set 
of rooms of this Institution were thrown open, and were filled by 
members who exhibited a vast variety of objects—many of them living 
—and apparatus of novelty. Tea and coffee were served in an ad- 
joining apartment, and altogether the meeting was a most pleasant 
and successful one.
