8. An outline of the Geology of Canada, based on a subdivision 

 of the Provinces 'into nat urai 'areas; by E. J. Chapman, Prof. Min. 

 and Geol., University College, Toronto, Canada. 106 pp. 8vo, 

 with several maps and plates of fossils. — Prof. Chapman's work is 

 a brief resume of the facts in Canadian geology, preceded by an 

 Introduction, of 32 pages, on rock-formations and divisions of geo- 

 logical time. The work is a convenient one for the student and 

 also for the geologist who would acquire a general knowledge of 

 iirit isl i- American Geologv. It contains six plates of fossil- repre- 

 senting Canadian species:

 has a valuable paper on this subject in the American Naturalist 

 for October and November.

 Ma,,, bv .J.vmks Gkik.ii':, K.H.S., of H. M. Geological Survey of 

 Scotland, lid edit, revised. 024 pp. 8vo, with several maps and 

 numerous illustrations. London. 1877. (Daldy, Isbister & Co.). 

 —In this second edition, Prof. Geikie's very popular work has 

 received various additions from recent observations, partly per- 

 sonal, made in Britain, and from researches in other countries. 

 America included ; and, as the author's preface states, much of it 

 has been rewritten. The subject is well treated in all its different 

 hi lies, and the illustrations' are excellent. The maps include one 

 of North America, showing the southern outline of the glacier and 

 the general courses of erosion. Among the changes of views 

 introduced, are the use now of the terms till an, 1 bowlder clay 

 " as strictly synonymous ;" and the adoption of the conclusion of 

 Mr. Jamieson, that " the sea had not any share in the formation of 

 the kames." The work is the best review of the subject to be had, 

 and owes much of its value to Professor Geikie's own researches. 



III. Botany and Zoology. 



1. Date of Publication of Elliott's Botany of South Carolina 

 a,,d Georaoi.— -The title-page of the first volume bears the date 

 of 1821. But it is well known that the work was issued in parts. 

 and that the publication began much earlier. The actual time of 

 issue becomes important in "respect to the priority of certain ge- 

 neric and specific names, notably those in Nuttall's Genera, pub- 

 lished in 1818. Contrary to the testimony of the title-pages, it is 

 uei.erallv umle.-tood that Elliott's names of Podostigma and 

 Acerates have priority over Nuttall's Stylandra and Ananthrrb: 

 To avoid future trouble it is desirable to put upon record such 

 evidence upon the point as is now obtainable. The only printed 

 testimony vet met with is in the /. "*, the cor- 



e's ablest collaborator), 

 lovingly edited b v his friend. !>r. Darlington. By reference to 

 pp. 202' Jl- 2+0 ' and js.->. it is made out that the first number of
