made more than fifty thousand notes according to this new sac ign 
recording. He has also given us, from his ‘register, examples

commonness or rarity of certain plants, and will be led to study 
more the correlations of species to the soils on La: ch they grow, to 
the — in which they are found, to altitudes at ee 
they occur. There is interest in knowing he plants are found in 
sw vice-county, or river-area ; i — essa is greatly in- 
creased, if, in that county, vice-county, or river-area, we can see 
why, in some parts of it, certai i glans are yon which it would 
be useless to look for in others. , in a bota nical excursion, the 
author’s method were adopted, we should gain much greater know- 
ledge of our plants and their environment, as well as far greater 
pleasure in our study of them. But whether they adopt the new 
method or not, all totais ts will find much to interest them in the 
very able paper which is the subject of this notice. W.F.

A certain melancholy interest attaches to this book in that the 
author was seeing it through the press when his Roe illness and 
death ended a career rich in botanical work. Few men have ranged 
seen eg great a ER t in the Berlin school of s aan 
bo humann has peoebly seconded the efforts of his chief— 
Professt Engler—towards that development. He was one of the 
chief contributors to Tengler's Jahrbuch from its foundation; his 
was the first contribution, serving as a pattern for those that follow, 
to the great Pflanzenre eich, for which he monographed the Musacea, 
followed later by the

had made important contributions, including two useful papers on 
the inflorescence. He also o produced a general Text-book of Botany. 
The subject of the present review is also a book for students. 
The plan is an original one. author has selected a number of 
seed-plants (about : a hundred and “fifty) for a detailed morphological 
description, to serve as an introduction to serious systematic work 
based on the morphology of the peclative floral, and ee organs. 
irections are given for collecting specimens of the mature plant in 
various stages, followed by a description of the chief dine of interest
