neglected county, so far as its geology was ^concerned, but since 

 1867 the researches of Prof J, W. Judd, which have been published 

 by the Geological Survey in the shape of map and memoir, have 

 pretty well exhausted the subject. 



Mr. Harrison describes the Liassic and Oolitic rocks, and the 

 Post-Tertiary gravels and clays, noting all the economic features 

 and other points of interest. 



We should have mentioned that in describing the Geology of 

 Leicestershire, due acknowledgment was made of the observations 

 of other geologists — of Mammatt, Jukes, Potter, the Eev. W. H. 

 Coleman, Hull, Ansted, and others. And we may add that the 

 photographic illustrations, which to the number of twelve are 

 scattered through the volume, are well executed, and represent, as 

 clearly as photographs can, some of the grandest facts in the 

 geology, which have been so carefully described and arranged in the 

 letterpress by Mr. Harrison. H. B. W. 



III. — Lyman's Geological Survey of Japan.^ 



T is now nearly three years since we noticed in Dec. II. Vol. I. 

 of the Geol. Mag. the preliminary report on the first season's 

 work of the Geological Survey in the Island of Yesso. We have 

 now before us four extremely detailed reports, making up over 900 

 pages of letterpress, with numerous maps, said to have an area of 

 190 square feet : the whole recording the operations of the Survey 

 down to the year 1876. 



Mr. Lyman does not appear to have allowed the grass to grow 

 under his feet ; and with the characteristic energy of our American 

 cousins, we find that sickness was not permitted to arrest his 

 progress, though the cure adopted was starvation ; also, when thrown 

 from his horse and seriously injured, he had himself carried, thus 

 performing long journeys. 



It speaks well for the capabilities of Japan that he has been able, 

 within so short a time, to train native assistants, with the aid of but 

 one fellow-countryman (Mr. Munroe), not alone in geology, but in 

 surveying and mapping, so as to produce the very highly creditable 

 results before us. 



The printing of the reports is most excellent, clear and neat, the 

 paper white and good, and though they have only stiff paper covers, 

 they have a tasteful and business-like look, most having an index, 

 and all possess the great advantage of clean cut edges. The maps, 

 too, are well lithographed and photographed, faithfully reflecting 

 Mr. Lyman's own stj'le. They look perhaps rather crowded, but it 

 is from the effort to make them contain all the information possible, 

 in both Japanese and English writing, the latter in somewhat large 

 thin block character, probably the most easily acquired by native 

 draughtsmen. They have also contour lines to show the form of the
