The Rev. Richard Baron, F.G.S., of the London Missionary Society, has sent to the British Museum some interesting reptilian remains from the Jurassic rocks of Madagascar, which he obtained during 1891, at Andranosamonta village, a locality situated in the north-western part of the Island. They were enclosed in a tenacious slielly limestone, so that before their examination could be proceeded with it was necessary to submit them to careful development and cleaning, a work whioh has been most ably carried out by Mr. Richard Hall, the Assistant Formatore of the Geological Department.

Some of this miscellaneous series of old fossils have been in the collections in the British Museum many years; but, owing to their small size and doubtful characters, they have not found an abiding place in any special zoological group.

A thick mass of bedded schists, as I have described in more than one paper, occupies the highest position among the socalled metamorphic rocks of the Alps. With the exception of some gneisses—so far as I know of a porphyritic character, and almost certainly intrusive granites modified by pressure— and various green schists, which, in part at least, are basic igneous rocks, similarly affected, the group, which may be traced from one end of the chain to the other, consists of altered sediments.

The Quarterly Journal of the Geological Society, for 1892, contains a paper by Mr. H. W. Monckton, F.G.S., embodying a useful and valuable collection of observations tending to throw additional light upon the history of the surface-changes, which have taken place in the higher parts of the London Basin in later Tertiary and Quaternary times. The theoretical views put forward in that paper have not, however, altogether the novelty which the author seems to claim for them. He is wrong in coupling my name with that of Prof. Rupert Jones as an advocate of a partial marine origin of the gravels, and so claiming novelty for the theory (p. 45) “that all the gravels in the area dealt with were formed after it had for the last time risen above the sea.” A few quotations will put this in a clear light.

At the meeting of the Geological Society on February 8th, Mr. Teall exhibited, as one of the illustrations of his paper “On some Coast-Sections at the Lizard,” an eminently characteristic and instructive diagram of serpentine and granite in juxtaposition; and the interesting question whether the granite was intrusive in the serpentine or vice versa, was ventilated and discussed, but by no means decided.

In the course of the summer 1892, I had occasion to visit and examine the drainage area of the Lake of Zurich, including that of the Wallensee; and this gave rise to some interesting observations relating more especially to the origin of those lakes, to the high degree of purification of their waters by chemical and mechanical agency, and to some noteworthy effects of certain geological changes in their watersheds.
