2. — La Ronde Ghent inee, ?iear Les Gr ancles Mielles, GdteL 



A small quarry has existed in this locality for a very 

 long time, but it has recently been extended by working the 

 outcrop of rock on its northern face, exposing a good deposit 

 of beach pebbles, though only about 20 feet in length. Its 

 height above sea level is from 23 to 28 feet, so that it also 

 corresponds with Mr. Collenette's 25 foot beach. Its distance 

 from high water mark in " Port Soif " is 1,300 feet, from low 

 water mark 2,300 feet. 



B.~ROCKS.-HORNBLENDE GABBRO. 



The rock so named by lie v. E. Hill has long been known 

 to exist on the east coast of the island from Hougue-a-la-Perre 

 to St. Sampson's Harbour. It has lately been noted at 

 Noirmont (near the Old Mill) and at Les Maingys, where it 

 passes into the ordinary diorite and syenite, and this may 

 mark its westernmost extension. The gabb:o may therefore 

 be said to be comprised in a band of from half-a-mile to a mile in 

 width ranging W.N. W. to E.S.E. ; though the rock in question 

 does not occupy the Avhole area of this band, but appears on 

 the surface as a series of disconnected outcrops, forming as it 

 were islets in a sea of diorite and syenite.

Report of the Botanical Section. 



Several Flowering Plants of great interest have to be 

 added this year to the Sarnian Flora, owing to the visit to 

 these islands of one of our ablest field botanists, Mr. G. 

 Claridge Druce, M.A., F.L.S., the author of the Flora of 

 Oxfordshire and the Flora of Berkshire. Mr. Druce greatly 

 enjoyed his visit to Guernsey, during which I had the pleasure 

 of accompanying him in most of his i-ambles ; and he also 

 made various excursions to Alderney and Sark, with good 

 results. There are still a few critical plants collected in these 

 islands to be worked out, notably species of Fnmaria. and 

 Ruhus^ but these I hope to be able to record in next year's 

 Report. 



A paper on the Mosses and Hepaticie of Jethou, enume- 

 rating fifty-five species, Avas recently read before the Society, 

 and will be published in the Transactions. This completes 

 the record of the bryology of all the islands within our area.
