PHYTOGRAPHY. 
BOOK IV. 
cial mention must be made of the drawings of Palms, and 
the figures that illustrate Von Martins’s Nova Genera et 
Species Plantarum ; Turpin’s plates in Humboldt and Kunth’s 
Nova Genera Plantarum^ and in Delessert’s leones Plantarum ; 
and some excellent analyses the parts of fructification of 
Rhamnaceae and Bruniaceae, in his memoirs upon those orders, 
by Adolphe Brongniart. 
Almost every scientific work of reputation, of the present 
day, contains figures which are formed upon the models of those 
now enumerated ; from which they differ in the quantity of 
analysis that is introduced, a circumstance generally regulated 
by the price at which they are published. 
Of anatomical plates, the best are those of Link, in his 
folio work on vegetable anatomy ; of Mirbel, in his Memoire 
sur V Ovule ; of Adolphe Brongniart, in his vai’ious papers in 
the volumes of the Annales des Sciences; and especially of 
Mohl, in his illustrations of the anatomy of Palms and Tree 
Ferns. 
I have mentioned these as instances of good drawings, 
because they are easily accessible, and incontestably are well 
adapted to improving the taste and execution of a student ; 
but there are other modern works, in which the figures may 
be also studied with great advantage. Whatever bears the 
name of Francis or Ferdinand Bauer, Hooker, Greville, 
Mirbel, Decaisne, Schleiden, L. C. Richard, Miss Drake, 
Mohl, or Turpin, may almost always be profitably studied. 
A very ingenious method of ohidJmmg photogenic drawings, 
or faC”Simile representations of plants, by the action of light 
upon paper prepared with some of the salts of silver, has 
lately been invented by Mr. Henry Fox Talbot ; and the art, 
if it should prove possible to use it for practical purposes, 
would be of great value : but too little is as yet known of its 
application, to enable me to speak confidently upon this point.
