42 Reports and Proceedings : 
Nine species, including Cytherea chione, have also been obtained - 
from the patch of gravel discovered by Mr. Prestwich, at about 1,200 
feet above the sea, on the east side of Macclesfield. 
Tuer Natura History Society or NORTHUMBERLAND, DURHAM, 
AND NEWCASTLE-ON-Tyngz, held its first evening-meeting on Nov. 24, 
when a large and fashionable audience thronged the Museum of the 
Society in Westgate Street, Newcastle. A large number of the best 
microscopes and prepared objects were shown by members and their 
friends; and an address ‘On Museums: their Uses and Management,’ 
was delivered by Prof. Archer, director of the Industrial Museum of 
Scotland. 
Under the new arrangement, the Natural History Society and 
the Tyneside Naturalists’ Field-Club (which, preserving their in- 
dependent existence, have entered into fraternal association), com- 
menced their winter-evening meetings in the Walrus Room, on 
December Ist. 
Bristot Naturatists’ Socrety.— Geological Section, Oct. 28th.— 
Mr. W. Sanders, president, in the chair. Mr. J. Keal continued the 
discussion of the last meeting respecting the Lias beds of the neigh- 
bourhood, and gave an interesting account of his endeavours to 
discover the point of junction of the New Red Sandstone and the 
Lias, describing minutely the beds and fossils on Bedminster Down, 
the most noticeable of which were Terebratula psilonoti, at Colliker’s 
Brook—an evidence of Lower Lias, and Ammonites planorbis at 
Yanley Lane. Mr. Keal went at great length into the question at 
issue between Mr.C. Moore, of Bath, and Dr. Wright, of Cheltenham; 
and concluded by proposing as a problem for solution, the range of 
the Saurians in the Bristol district, and their relation here to the 
Ammonites planorbis, which, he was satisfied, occurred above the 
White Lias. Mr. Sanders confirmed the last remark, and said that 
he did not consider the Saurians to be confined to any one zone ; he 
pointed out the desirability of making a great number of accurate 
sections, to scale, of all the Lias beds, and correlating them, taking 
the Cotham or Landscape Marble as a good landmark from which 
to reckon vertical distances of beds, which should all be numbered, 
and notice taken of the fossils occurring in them. The Saltford 
section might be used as a model. Mr. W. W. Stoddart exhibited a 
large collection of fossil Entomostraca, or Water-fleas, which he had 
obtained from all formations—Silurian to Postpliocene. In the living 
state they were all aquatic, with two valves, and a chitinous skeleton, 
moulted yearly, which was the cause of the great abundance of their 
remains. With the exception of the well-known Trilobites, which 
he believed to belong to this class, they were all microscopic, and 
were obtained from the beds they occurred in, by disintegrating the 
stone with or without the use of hot and cold water, passing the 
powdered mass through sieves of various fineness, and picking out the 
minute fossils under a microscope.—Bristol Daily Post, Nov. 21, 
1864.
