ment it appears that the yield of gold for the quarter was 150,193 ounces. 
The ground actually worked upon was 324i'3 square miles. The mining 
population was 25,679, of whom 12,795 were employed in quartz-minings 
and 12,884 in alluvial mining. The Chinese miners number 3,980. The 
total of dividends paid was £117,214. The deepest shaft was 2,409 feet. 
The total value of the machinery employed was £1,815,731. The mining 
interests of the colony appear to be chietiy confined to gold, and their con- 
dition is prosperous. 
Prof. C. L. Hekrick has recently issued the third part of the bulle- 
tin of the laboratory of Denison University at Granville, Ohio. The prin- 
cipal part of the volume is occupied with a paper on the results of Prof 
Herrick's investigations on the Waverly group of Ohio. The fossils are 
described and a very large number of them are well figured. 
Prof. Herrick divides the Waverly into three parts and characterizes 
them palfeontologically as follows: 
No. I, contains 25 species with a decidedly Devonian habit (often close- 
ly related to Hamilton species) and only 2 or 3 species of Carboniferous 
habit. 
No. II, contains 13 species of Devonian afiinity (often Chemung) and 
9 of Carboniferous habit. 
No. Ill, contains no species showing Devonian relationship and 7 that 
indicate a Carboniferous habit. 
As the outcome of his study he is evidently inclined to place the 
Waverly group lower in the scale than has hitherto been done by geolo- 
gists. Of the second group he says: "Most of the str.ta may have been 
deposited while the Catskill was forming at the east but the fauna was es- 
sentially of Chemung character." 
It would require more space than we have at present at command to ex- 
press fully the work of Prof. Herrick, but we may say that he has made a 
valuable contribution to the solution of the vexed question of the true 
place of the Waverly in the geological column. 
Another article of geological interest in the volume, is by Mr. Aug. 
Foerste on some palaeozoic fossils. The chief species noted are Microdis- 
CU8 punctatus from the St. Johns' group, N. B., a new Lichas from the Cin- 
cinnati group which he proposes to name L. halli; the so-called Sphere, 
ochus romingeri, of Hall, which so far as the Ohio specimens are concern- 
ed, he says, is identical with the European S. mirms; and several new 
species of trilobites and corals from Australia.

208, pi. i-vi. The Society for the Propagation of Scientific Knowledge, in 
Vienna, has published under the above title, a work which, for its concise 
and comprehensive treatment of the general subject, as well as its special 
adaptation to the needs of working field geologists, is worthy of notice . 
The opening chapters are devoted to a discussion of the different kinds of 
coal, their properties and characteristics, and the results of numerous 
chemical analyses. Following this, the author treats of the geology of 
the palaeozoic coals and their geographical distribution, illustrated by
