Revieics — J. E. Lee's Note-hook of a Geologist. 379 



We ouglit to do Mv. Lee the justice to mention that in publishing 

 his sketches, his sole object has been to record facts. He says, " there 

 is not a single theoretical diagram amongst them," each sketch 

 represents what was actually seen, and hence they lack the clearness 

 of many published sections which represent the continuation of 

 strata too often concealed, or in other words, what ought to have 

 been seen; though we must not forget that many published longi- 

 tudinal sections simply give the explanations or opinions of the 

 expounder. Under such circumstances, Mr, Lee's efforts are praise- 

 worthy, while open to the objection of not always being sufficiently 

 explicit. 



At p. 87 Mr, J. E. Lee acknowledges the assistance of Mr, C. 

 Spence Bate, F,R.S,, who has contributed notes upon two crustaceans 

 forming the subjects of plates cciv, and ccv. It is rather unfortunate 

 for Mr. Lee that his friend seems to have been unacquainted with 

 this well-known fossil crustacean (pi. cciv,) so abundant in the 

 Lower Greensand of Atherfield, Isle of Wight, figured in Bell's 

 Fossil Crustacea, Pal. Soc. Mon. 1862, pt. 2, p, 32, pi. x. as Meyeria 

 vectensis ; but which Mr, Spence Bate erroneously names Mecochirus 

 Pearcei, M'Coy, — a minute Oxford Clay Crustacean from Wiltshire 

 with which this Greensand fossil has nothing to do. 



To criticize the work in a severely scientific point of view has not 

 however been our object. In turning over its pages we cannot 

 refrain from heartily s^anpathizing with the author : for we feel 

 assured that geology is largely indebted to him and others whose 

 genial enthusiasm in science acts as a spur and encouragement to 

 young geologists, and may be an example to those more advanced 

 in years.

 Part 3, June, 188L 



BESIDES much valuable information on new forms of microscopic 

 life, and on microscopes, their associated apparatus, and their 

 methods of use, detailed in the various papers and abstracts of papers, 

 we find in this June Number of the R, M, Society's Journal (at 

 pages 381 — 387, and p, 549) an interesting and carefully prepared 

 account of the fossil BlatomacecB of the London Clay, discovered by 

 W, H. Shrubsole, F.G.S. ; a coloured lithograph is supplied in illus- 

 tration. These are in a pyritized condition, and are very abundant 

 in the lower part of this formation, in a particular zone (366 feet 

 from the surface at Southend), extending over several square miles, 

 at Sheppey, and in the neighbourhood of London. They appear, 

 even to the well-diggers, as " shining spots " in the dry claj', " as if it 

 had been dusted with powdered sulphur, and sparkling in sunlight." 

 The method of separating these minute mineralized bodies from 

 the clay is given, together with remarks on their occurrence in the 

 different sections and well-diggings that were specially examined. 

 In some parts of the diatomaceous zone, the clay is somewhat laminated 

 by their presence. The pyrites has wholly replaced the original 

 silica in the majority of specimens examined, but occasionally some
