And what on earth inrlucerl the author to pen this sentence : " Le 

 nombre des chambres chez les Orthoceras est invariable " ? 



The publishers have secured numerous illustrations, the better 

 ones being reprinted from Professor Gaudry's " Enchainements du 

 Monde Animal," recently reviewed in these pages. But we regret to 

 see once more the caricature of Ichthyocrinus piriformis, that, under 

 the name of " Cyathocrinus pyriformis," disgraces p. 89. No Trigonia 

 ever had lines of growth like those drawn in fig. 82 ; the engraver 

 cannot have seen the shell. Fig. 106, a worse copy of a bad original 

 (Pictet 'Traite de Paleont.' pi. liii. fig. 6) hardly represents the 

 typical form of Amaltheus margaritatus. The drawings of Coccosteus, 

 Pterodactylus, and Megatherium are more than old, they are senile ; 

 it is to be hoped that their errors will soon pass to the land where 

 all things are forgotten. 



The printer seems to have placed the blocks at his own sweet 

 will; some Gasteropod and Cephalopod shells are placed with the 

 mouth upwards, others with it downwards, while even a skull of 

 Teleosaurus (fig, 149) is topsy-turvy. And here is a little sum for 

 him : if every volume of the ' Bibliotheque scientifique contem- 

 poraine ' has as many misprints as the present one, how many 

 thousands do they amount to ? F. A. B. 



V. — Transactions of the Leeds Geological Association. Part 

 VI. 1890-91. Edited by W. Lower Carter, M.A., F.G.S. 

 (Leeds, 1891.) 



A S indicated by the new part of its Transactions just received, 

 JrX the Leeds Geological Association still continues to maintain 

 its position as one of the most flourishing of provincial societies. 

 While specially concerned with the facts of Yorkshire Geology, 

 and devoting much time to field-excursions, the Association also 

 encourages the discussion of wider subjects of general interest ; and 

 useful abstracts of all the communications are comprised in the first 

 half of the Keport. The Presidential Address (by Mr. C. Brown- 

 ridge, F.G.S.) relates to the building and paving stones employed 

 in Leeds. Other contributions to local geology are entitled "A 

 Geological Tour through Durham into Cumberland " (by Mr. W. 

 Cheetham), "A Long-buried Oak" (by Mr. B. Holgate, F.G.S.), 

 "A Geological Episode as recorded in the Ingleton Granite" (by 

 Mr. T. Tate, F.G.S.), and "From Kettleness to Saltburn " (by Mr. 

 E. Hawkesworth). Among more general papers, Prof. A. Lupton 

 discusses "A Gold Mine, a Slate Mine, and a Salt Mine," while 

 Mr. J. E. Marr has some brief remarks on " The Backbone of 

 JEngland." Other readable summaries of special geological subjects 

 are also given ; and the latter half of the Eeport is devoted to a 

 well-written account of the Field Excursions, which will prove of 

 much value to all geologists who wish to study the district. The 

 Membership of the Association is well maintained, and the latest 

 additions to the list of Honorary Members are the names of Messrs. 

 J. B. Marr and A. Smith Woodward.
