NOTICES OF BOOKS. 187 
of clusters of flowers and fructifications generally, or leaves lying one 
over another, there will be the like obscurity in the impression. 
Whatever may be the superiority of Mr. Bradbury’s process over 
that in use at Vienna, we are not sensible of it in the instance of the 
work that stands second at the head of this notice; and we must 
maintain that Mr. Heyfleur’s work on the Carpathian Cryptogams and 
Mr. Moore’s on the British Ferns (as far as it has yet gone) are both 
very beautiful, and the more so because the authors have the good - 
sense to select the kinds of plants best suited to the process; and they 
are both entitled to very high commendations. In the Cryptogams of 
Mr. Heyfleur there is a variety and richness of colour which adds 
greatly to the effect, and the forms are quite as graceful as the Ferns. 
We think nothing can be more true to nature, in colour as well as form, 
than the Cladophora insignis, Ag., Tab. 1. It seems the plant itself. 
Sticta pulmonaria, L., on the other hand, wants colour and filling up. 
At Tab. 3, Agaricus androsaceus, L., is a blot, only showing form: and 
the other figures, Fungi, Lichens, and Alge, are good, in proportion 
as the specimens bear compression without losing their characteristic 
features. Tab. 4, the Jungermannia, are extremely beautiful. The rest 
of the plates are Mosses, and are excellent, except the capsules, which, — 
true to their originals, exhibit them bruised and crushed by pressure. 
The last plate of the noble specimens of Meesia triquetra and Mnium 
ligulatum would deceive an experienced Muscologist. 
In the‘ Ferns of Great Britain and Ireland,’ the only two species 
represented (on three plates) are Polypodium vulgare, with its varieties, 
and, in our copy at least, P. Phegopteris; and here, in all the fronds, and — 
there is no stinting of specimens on the noble pages, the greens are of 
the same unvarying pale, somewhat verdigris cast, happily a good deal 
relieved by the deep brown of the caudices and roots. As the art is ee 
new one, and no doubt capable of improvement, we my be permitted 
to say that the depth of surface-green on the fronds is insufficient, so 
that they have too much the character of what are usually called skeleton 
leaves; the nervation is of too prominent a character, and the paren- 
chyma wants substance; the green of it is of the same filmy nature : 
as seen in some of the more delicate hymenophylloid Ferns. If this 
deficiency be not remedied in the species of Polystichum, especially 
when the upper surface requires to be represented, ue doom be 
more injurious than in the present plates. :
