has just been erected. Some of this diorite, although 

 thoroughly disintegrated, retains its blue colour. In the 

 hollow betAveen these outcrops, a stratum of about 2 feet of 

 marine sand was found, underlaid by yellow earth (loess) and 

 that by clay with angular stones resting on the decomposed 

 diorite at a depth of 10 to 12 feet. This marine sand was 

 also found in the field where the pumping station is erected. 

 Here it is also about 2 feet in thickness, but rests directly on 

 the decomposed diorite.

In the excavation on the site of No. 8, recently 

 demolished, a fine section of the yellow earth (loess) was 

 exposed to a depth of about 12 feet, the bottom not being 

 reached. This loess consisted, as usual, of two kinds of 

 layers, both composed of sand and clay but in different pro- 

 portions. The more sandy layers, which in this case greatly 

 predominated, are lighter in colour than the more clayey ones, 

 and their particles are coarser, but none of the clay was 

 sufficiently fine to remain in suspension in water for any 

 length of time. The whole of the material appears to be 

 derived from the disintegrated gneiss of the district, and the 

 grains are not rounded in any appreciable degree, showing they 

 have not travelled far. The layers are as usual irregular and 

 somewhat contorted.

Report of the Marine Zoological Section, 1912. 



I am sorry that there is very little to report this year. 



It is most unfortunate that, although Ave possess in 

 Guernsey and the neighbouring islands almost unparalleled 

 opportunities for Marine Zoological investigations, due not 

 only to the physical conditions of our coastline, but also to 

 the exceptionally large rise and fall of the tide here, Ave are 

 still Avithout workers. The only addition to our list this year, 

 and one that I cannot find recorded as having been discovered 

 anywhere else, and therefore not yet named, is a variety of 

 the daisy anemone — Sagartia bellis — with bright red tentacles. 

 Five specimens were discovered by myself in a crevice of rock 

 near Moulin Huet in September. 



For about a fortnight in June Ave had carried to our 

 shores — principally along the Western coast — enormous 

 numbers of two tropical and sub-tropical marine creatures. 

 Pliysalia, the "Portuguese Man-of-War," and a smaller
