258 Notices of Books. [April, 



other sciences than the one to which he especially applies him- 

 self, and to the general reader who wishes to keep au courant 

 with the scientific knowledge of the day. It is not, of course, 

 from such works as these that the man of science learns the 

 depths of what he requires to know, but there are few so thoroughly 

 well read in all the branches of physical science that they will 

 not find here some knowledge they have partially acquired brought 

 to a focus, and the means of increasing that knowledge suggested 

 to them. 



We hope that the somewhat enigmatical notice facing the title 

 page, "that this series is published under the sole direction of 

 J. Bertrand Payne," may mean that the other sciences may 

 obtain like attention to that bestowed upon them by Mr. Rodwell 

 and his coadjutors. 



Geology; By John Morris, F.G.S., Professor of Geology and 

 Mineralogy, University College, London, &c, and T.Rupert 

 Jones, F.G.S., Professor of Geology and Mineralogy, Royal 

 Military College, Sandhurst, &c. First Series. London : 

 John Van Voorst, Paternoster Row, 1870. 



We learn from the preface that the intention of the authors is 

 that this work should be considered as a concise guide book, so 

 arranged that it may be useful both to students and teachers of 

 geology. This first series consists of heads of lectures and 

 synopses, with a table of the geological formations in the British 

 Isles. Small as this book is, it is a real multum in parvo. It is 

 excellently arranged, thoroughly methodical, and its contents 

 may be readily retained in the memory. On this account it will 

 become an important and valuable assistance to the study, not 

 only of geology, but of what we may term the natural history and 

 physiognomy of the entire mineral kingdom. 



Civil Engineers' and Contractors' Estimate and Price Book for 

 Home or Foreign Service. By W. Davis Haskoll, 

 C.E., Author of "Railway Construction," &c. Blackwood 

 and Co. 



This work is compiled to assist the engineer in preparing estimates 

 for tenders for public works, one of his most important duties, 

 and which affects his professional reputation most directly. It 

 is in two parts, one giving the particulars of price, &c, in matters 

 relating to the estimate, the second part being a priced list of 

 contractors' machinery, plant, and tools. Even the experienced 

 engineer or contractor may have his attention called, upon a 

 glance at this book, to matters which in the haste of estimating 

 might otherwise be forgotten.
