GLIMPSES INTO PLANT-LIFE. ARTICLES IN JOURNALS. 459 



a number of floral diagrams which illustrate " Grundformenver- 

 haltnisse." In the primrose with its regular pentamerous whorls 

 we have for a grundform a regular five-sided pyramid. In Parnnssia 

 the regularity is spoiled by the introduction of a four-sided pistil, 

 while in Cainpanula a x'egular three-sided pyramid (represented by 

 the pistil) is combmed with a regular five-sided one in the outer 

 whorls. In the disc-florets of the ComposiUt. a regular five-sided 

 pyramid is combined with a subi'egular one whose base is a rhombus. 

 And so on. The next chapter, " Voui Mechanismus der Keimes- 

 geschichte," deals with the structure and properties of protoplasm, 

 nuclei, and other cell-contents. Movements, spontaneous and in- 

 duced, are treated in Chapter IV. (Vom Forinbildungsgrund). 

 Chapter v., is on '• Form changes," and Chapter VI. and last on 

 the Mechanism of Phylogeny. The book concludes with a copious 

 bibliography, arranged in chronological order, followed by an index.

Glvnpses into Plant Life : an Easy Guide to the Study of Botany. 

 By Mrs. Brightwen. With illustrations by the Author and 

 Theo Caureras. 8vo, pp. 851. London: Fisher Unwin. 

 Price 3s. 6d. 



This is an excellent specimen of the best kind of "popular" 

 book, and contrasts very favourably with many which are issued — 

 e.(j. with Mr. E. A. Martin's Nature Chat, which we noticed on 

 p. 365. It is unpretentious and simply written, and is free from 

 the speculations dear to the Grant Allen school of scientists ; and 

 the youthful reader, for whom it is primarily intended, will at any 

 rate have nothing to unlearn, which is more than could be said for 

 many more pretentious volumes. Like Mrs. Brightwen's other 

 books, it shows much quiet observation and considerable acquaint- 

 ance with the literature of the subject ; the illustrations are new 

 and are, with hardly an exception, good. The book is in fact what 

 it claims to be, " an easy guide to the study of botany," and it may 

 be safely recommended to those who have the charge of young folic.
