out by Mr. Jenkins, they have nothing to do with the Nar or its 

 valley ; probably they are representatives of the " Middle Drift " of 

 Mr. S. Y. Wood, jun. The Brick-earth here lies in the river-flat ; it 

 is well known from the writings of Mr. C. B. Eose and the late 

 Mr. Triminer. 



6tli. Pitchill Tilesford, and the Grove Farms, Worcestershire. By 

 H. M. Jenkins. — These farms are principally on Lias Clay, but there 

 are traces of Ehaetic, and Keuper beds, also Boulder-clay and sand. 



7th. Bulbridge and TJgford. near Salisbury. — The area occupied by 

 these farms is chiefly Chalk, which here gives a thin chalky soil, 

 especially thin and chalky on the higher land. 



The reports are illustrated by small maps, some on the scale of 

 1-inch to a mile, others on a scale of 2-inches to a mile. Most of 

 them have been specially prepared by Mr. H. M. Jenkins. 



A good geological map of England, showing the Drift deposits, 

 would, doubtless, be of great service to Agriculturalists. Mr. Searles 

 V. Wood, jun., has done much valuable work in paving the way 

 by preparing and publishing Maps of the Eastern Counties (inclu- 

 ding Lincolnshire and part of Yorkshire), whereon the chief divisions 

 of the Drifts are laid down. But these maps, although of the highest 

 scientific interest, ai-e on too small a scale to be of much practical 

 service. His beautiful MS. Memoir and Maps of the Geology on 

 sheets 1 and 2 of the Ordnance Survey, deposited in the Libraiy of 

 the Geological Society of London, are probably not so well known 

 as they should be. 



It is satisfactory to learn that the Geological Survey of England 

 are preparing maps of the Drifts, where formerly they ignored these 

 deposits. The want of these is evidently felt by Agriculturists, 

 who will, doubtless, derive much benefit from this new feature in 

 the Geological Survey Maps.

Geological Society of London. — November 10th, 1869. Prof. 

 T. H. Huxley, LL.D., F.E.S., President, in the Chair. The following 

 communications were read : — 1. " Australian Mesozoic Geology and 

 Paleeontology." By Charles Moore, Esq., F.G.S. The author 

 referred to the observations of Professor M'Coy and the Eev. W. B. 

 Clarke, on the occurrence of fossils of Mesozoic age in Australia, and 

 then proceeded to notice the species which he had obtained from that 

 region. Fossils of Mesozoic type occur both in Western Australia 

 and in Queensland ; but the specimens have hitherto been found in 

 apparently drifted blocks, and nothing is known of the bedded rocks 

 from which they are derived. The author stated that the Australian 

 Mesozoic fossils agree, not onlj^ in genera, but also in many cases in 

 species, with British forms ; and he gave a list of species from 

 Western Australia, identical with British species, from the I\Iiddle 

 and Upper Lias, the Inferior Oolite, and the Cornbrash. Of the 

 fossils from Queensland, also, many are said to be identical Avith, or
