The Quarterly journal of the Geological Society of London . ge numberof sections, showing the succession of the beds, and illustrating hisviews on the Bajocian denudation, which could be followed withinterest by all his hearers ; but when he entered upon the questionof the ammonite-fauna, he used so technical a nomenclature thatonly those who had learnt its significance in detail could readilyfollow his views. Mr. H. B. Woodward complimented the Author on his carefuldetailed work, and said that he differed from him mainly on mattersof nomenclature, and not with regard to the general succession ofthe strata and their fossils. Months upon months of labour in eachquarry would, however, be necessary to test the value of the minutedivisions made by Mr. Buckman. Without such prolonged workone could not tell how the distribution of fossils might vary in eachlayer of rock, and he would hesitate to regard the absence of anyhemerae as indicative of a break in the series of strata.

The Physical Features and Geology of Mauritius. By MajorH. de Haga Haig, , (Read April 3rd, 1895.) [Abridged.] [Plate ] I. Physical Features. The Island of Mauritius is the centre of a line of three—Reunion,,Mauritius, and Rodriguez—some hundreds of miles apart; they areall volcanic, and in reality quite unconnected, except in so far asthey are on a line of volcanic action. Mauritius is about 40 mileslong and 27 miles broad, and it consists essentially of a mass ofvolcanic debris thrown up from craters now extinct. A centralridge, which is the main watershed of the island, and in whichare situated all the more recent craters, commences at the south,where it has an elevation of about 2000 feet, and runs north-wards, gradually curving to north-east.
