bined into one alphabet, and the Adversaria synonyms included ; 
but this is almost the only word of fault-finding we feel disposed to 
utter. We close the volume with a feeling of gratitude to the 
author for much that is novel, not only in the actual facts brought 
together, but in the new light shed on old familiar things. The 
satisfactory accomplishment of this must have entailed an amount 
of labour incredible to any who have not themselves taken part in 
siciae work, M. Legré says that this is an instalment of work on 
the flora of the south; when we next meet with him, may we find 
him equally interesting. B. Daypon Jackson.

Dr. Werrsreiy’s essay consists of four chapters. In the first he 
discusses the present-day problems of —— botany and the 
attempts which have hitherto been made to a rthem. On the 
one hand, it has to supply a clear and eae: apie of all known 
plants; on the other, to give an idea of their phylogeny. The 
older school of botanists were occupied merely with the former 
task; a newer school, often with a contempt for earlier work, goes 
to the other extreme, ‘and loses itself in theoretical speculation on 
affinities. Most systematists will agree with Dr. Wettstein’s dicta 
that (1) a Soe. ma phylogenetic system is impossible, and we mus 
be sati if our system represents as far as possible views on 
claims to have established. But, before wpebegeae the new method, 
he dilates (in Chapter II.) on the inadequacy “of morphological 
development of the stem. In Cha oe er III., after pointing out the
