in favor of the foot-print origin of the fossils. The author 

 answers the arguments severally that are presented by Mr. 

 Nathorst, while admitting the great interest of his investigation. 

 But Mr. Delgado's most impressive argument is presented in the 

 various figures of the remarkably fine specimens which he has 

 obtained from the quartzyte of Portugal. The size, perfection, 

 regularity of markings, and other characters, appear to place it 

 beyond question that the larger forms at least are not mere 

 tracks or markings on a bed of sand or mud. The many plates 

 are phototypes of great perfection and beauty. The author 

 reviews the literature of the subject, describes and figures the 

 species of the Portugal quartzyte, some of them new, and cites, 

 with remarks and figures, the published species of other regions. 



4. The Geology of England and Wales, with Notes on the 

 Physical Features of the Country; by H. B. Woodward, of the 

 Geological Survey of England and Wales. 670 pp. 8vo. London, 

 1 887. (G. Philip & Son). — This second edition of Mr. Woodward's 

 Geology of England and Wales has received large additions 

 in its preparation, and been brought down thereby to the 

 year of publication. After a brief review of the subject of 

 stratigraphy that of nomenclature is briefly considered, ending 

 in the decision to use the old accepted terms in the pi'esent 

 state of unsettled opinions. The Cambrian period is made to. 

 cover the whole of the Lower Silurian, as proposed by Sedg- 

 wick, in recognition of the fact that the most marked and general 

 physical break in the formations between the top of the Paleo- 

 zoic and the Archaean is that separating the Upper and Lower 

 Silurian. The work then commences with the Archaean rocks 

 and era, and presents the general and local facts, stratigraphical 

 and geographical, for each period, with much detail and precision, 

 and with a notice of the characteristic fossils. The reader derives 

 from the work also a knowledge of the history of recent develop- 

 ments of the science, and numerous references are given to 

 memoirs and other publications. The work has many illustra- 

 tions, but none of fossils — the figures of which make so prominent 

 a part of the large work on general geology by Etheridge and 

 Seeley. It is accompanied by a large well-colored geological 

 map. The series of geological formations is far more nearly com- 

 plete in Great Britain than in any investigated area of equal 

 extent over the globe ; and a treatise on its local geology has, 

 therefore, universal interest. 



5. Geologie von JBayem, von Dr. K. N. von Gtjmbel. Erster 

 Theil, Grundzuge der Geologie, Lieferung 4. — This 4th part of 

 Dr. Giimbel's excellent work carries the volume to p. 960, and 

 the descriptions of the geological formations from the Jura (p. 

 721) into the Pliocene. The page is large, the type rather small, 

 so that a great amount of matter is presented ; and the excellent 

 illustrations are very numerous for each of the successive subdi- 

 visions. The profusion of figures will be appreciated from the 

 single fact that those of the Pliocene alone represent more than a 

 hundred species.
