time, drifts into tlie same abuse. Altogether we are in a pretty 
kettle of fish, and the water is getting warm, but as by jumping out of 
it we should only fall into the fire, we prefer simmering a little longer. 
After all, the disturbance which Prof. Parlatore threatens us with 
is not so fundamental. Like a sound Chartist he holds by five points, 
types as he terms them. Here they are—“ These general types,” he 
says, “ of plant-structure are, in my opinion, five in number. 1st. 
The type of Cellular plants; 2nd. of Pibro-cellular plants; 3rd. of 
Vascular Cryptogams ; 4th. of Monocotyledons ; 5th. of Dicoty¬ 
ledons.” 
Our readers will see that, excepting the clumsy distribution of 
the Acotyledons, Prof. Parlatore’s plan is that which is almost uni¬ 
versally acknowledged and adopted. The term Acotyledon he drops, 
the character which it involves being negative. His third type of the 
Vascular Cryptogams includes, curiously enough, Characeae; a set 
of plants in which we imagine the ‘ vascular’ element must be very 
difficult to make out. His use of the words Mono- and Di-cotyledons 
is under the special protest, which few botanists would think it worth 
the while to enter, that in employing these terms he does not wish it 
to be implied that he attaches exclusive importance to the presence 
of but one or two Cotyledons in the embryo of the respective groups, 
but that he has a regard to the entirety of their organisation. 
It does not appear to be necessary here to enter into any further 
detail as to Prof. Parlatore’s views. Upon the whole we may say that 
we very fully coincide in them, as indeed we suppose nearly all bota¬ 
nists must do. But we cannot grant that our systematists have been 
so ‘ artificial’ in their practice, and so contracted in their conception 
of a truly natural method as Parlatore would make out in his ac¬ 
count of the progress of philosophical system from the days of Cse- 
salpinius, Morison,. Bay and Gresner to the present age. 
In a foot-note we observe the following reference to the Darwi¬ 
nian theory of the origin of species by variation and natural selec¬ 
tion : “ Le lecteur comprendra que je ne partage pas cette theorie, 
que je considere comme une hypothese tres ingenieuse, mais qu’a 
mon avis nul fait constate peut demontrer comme vraie.” 
Professor Parlatore’s little book is dedicated to M. Ad. Brong- 
niart, of the Institute, &c. &c.

Many interesting papers on the Cryptogamia appear from time to 
time, in the periodical named at the head of this article, and the 
completion of an annual volume is a convenient period for a survey 
of the contributions which its pages afford to the advance of Crypto- 
gamic Botany. In the present volume, we find that, with the excep-
