Reviews — Neues Jahrhuch fur Miner alog'ie, etc. 131 



Surely, if the work be worth doing at all, it should be done well and 

 thoroughly, and we should be among the first to welcome any 

 repentance on the part of the Colonial Government, that would be 

 shown in the appointment of a fresh staff, equally efficient, and as 

 well, if not better, paid, than tho old G-eological Survey of Victoria.

 LOGiE. Von G. Leonhard und H. B. Geinitz ; 1869, Hefte 2-7 ; 

 1870, Hefte 1-5 ; and General Index for 1860-69. 



EIGHTEEN months have slipped by since we noticed the current 

 numbers of Leonhard and Geinitz's " Neues Jahrbuch," see 

 Geol. Mag., Vol. VI., p. 272. The appended classified list of the 

 original memoirs in the subsequenit numbers, as far as they have 

 reached us, shows that diversity of subject in the main branches of 

 our science is well sustained ; and the treatment of the subjects, and 

 the names of the authors, together with those of the many corre- 

 spondents to the " Neues Jahrbuch," testify to wide-spread and sound 

 science among our German brothers in geology, who keep up their 

 title to the upper places among Cry stallographists and Mineralogists, 

 and are second to none in Paleeontology and general Geology. In 

 fact, the following catalogue of subjects specially treated of will 

 speak for itself ; and when we remember that these are associated 

 with an excellent bibliographical record of geological and minera- 

 logical works, with letters on current news and late discoveries, and 

 vsdth careful digests of hundreds of books and memoirs, we feel 

 bound again to call the earnest attention of our readers to this in- 

 valuable periodical, and to congratulate Germany on the industry, 

 acumen,, and good work of her geologists.
