Botany and Zoology. 501 



Heim, a Zurich, 154, pp. 8vo. Zurich, 1888. — This memoir is a 

 thorough systematic descriptive review of the various kinds of 

 faults or displacements, flexures and folds, in rocks, with defini- 

 tions of the terms used by writers on the subjects, and is both in 

 the French and German languages. Its illustrations are numerous, 

 and illustrate well all the various conditions of rocks described, 

 and its references to authorities are very full. It is therefore an 

 excellent aid to the geological student.

Ueber krystattographische Demonstration mit Hilfe von itork-

 Victor Goldschmidt. Berlin, (Julius Springer.) — Something more 

 than a year has passed since the completion of the first volume of 

 Goldschmidt's Index (see this Journal, xxxi, 475, xxxii, 485.) 

 The work which the author has undertaken is a formidable one 

 involving a heavy amount of labor for him, and yet benefitting 

 greatly all workers in this line ; it is to be hoped that he may before 

 long be able to bring it to a successful completion. The numbers 

 now issued (in separate parts for the convenience of those using 

 the work) cover all mineral species in F, G, H, with also quartz 

 (vol. Ill, No. 1), and the execution is of the same excellence 

 as in the earlier parts. The scheme of notation with the 

 methods of projection and calculation which the author 

 has developed with such exhaustive completeness in the Intro- 

 duction to vol. I of the Index are further elucidated in the ac- 

 companying memoirs. The reader who masters them fully will 

 be better able to appreciate the advantages of the author's 

 method. An ingenious device is adopted for the purpose of 

 demonstration by the use of cork blocks with needles bearing 

 colored heads to show the symmeti-y of the different systems and 

 the relation of the forms belonging to them.

1. Flora of the Hawaiian Islands ; by William Hillebea:nt>, 

 M.D. Annotated and published after the author's death, by W. 

 F. Hillebrand [New York, B. Westermann & Co. 8vo, p. 673, 

 with 4 maps of the Islands.] 



Dr. Hillebrand resided for twenty years in Honolulu, engaged 

 in the successful practice of an exacting profession, finding recre- 

 ation in an exhaustive study of the vegetation of the Sandwich 

 Islands. The plants were examined by him not only in their 

 native haunts but also after they had been transferred to his gar- 

 den, where they could be investigated under the most favorable 

 conditions. In this way he accumulated the materials for his 

 Flora. These materials were carefully elaborated during his 

 examinations of the leading Herbaria, and the work was ready 

 for the printers early in the summer of 1S86.
