neglected county, so far as its geology was concerned, but since 
1867 tlie researckes of Prof. J. W. Judd, whick kave been publisked 
by tke Geological Survey in tke skape of map and memoir, kave 
pretty well exkausted tke subject. 
Mr. Harrison describes tke Liassic and Oolitic rocks, and tke 
Post-Tertiary gravels and clays, noting all tke economic features 
and otker points of interest. 
We skould kave mentioned tkat in describing tke Geology of 
Leicesterskire, due acknowledgment was made of tke observations 
of otker geologists — of Mammatt, Jukes, Potter, tke Eev. W. H. 
Coleman, Hüll, Ansted, and otkers. And we may add tkat tke 
pkotograpkic illustrations, wkick to tke number of twelve are 
scattered tkrougk tke volume, are well executed, and represent, as 
clearly as pkotograpks can, some of tke grandest facts in tke 
geology, wkick kave been so carefully described and arranged in tke 
letterpress by Mr. Harrison. H. B. W. 
III. — Lyman’s Geological Survey of Japan . 1 
I T is now nearly three years since we noticed in Dec. II. Yol. I. 
of tke Geol. Mag. tke preliminary report on tke first season’s 
work of tke Geological Survey in tke Island of Yesso. We kave 
now before us four extremely detail ed reports, making up over 900 
pages of letterpress, witk numerous maps, said to kave an area of 
190 square feet : tke wkole recording tke operations of tke Survey 
down to tke year 1876. 
Mr. Lyman does not appear to kave allowed tke grass to grow 
under kis feet ; and witk tke ckaracteristic energy of our American 
cousins, we find tkat sickness was not permitted to arrest kis 
progress, tkougk tke eure adopted was starvation ; also, wken tkrown 
froin kis korse and seriously injured, ke kad kimseif carried, tkus 
performing long journeys. 
It speaks well for tke capabilities of Japan tkat ke kas been able, 
witkin so sliort a time, to train native assistants, witk tke aid of but 
one fellow-countryman (Mr. Munroe), not alone in geology, but in 
surveying and mapping, so as to produce tke very kigkly creditable 
results before us. 
Tke printing of tke reports is most excellent, clear and neat, tke 
paper wkite and good, and tkougk tliey kave only stiff paper covers, 
tkey kave a tasteful and business-like look, most kaving an index, 
and all possess tke great advantage of clean cut edges. Tke maps, 
too, are well litkograpked and pkotograpked, faitkfully reflecting 
Mr. Lyman’s own style. Tkey look perliaps ratker crowded, but it 
is from tke efifort to make tkem contain all tke Information possible, 
in botli Japanese and Englisk writing, tke latter in somewkat large 
tkin block ckaracter, probably the most easily acquired by native 
draugktsmen. Tkey kave also contour lines to skow tke form of tke
