AN INTRODUCTION TO THE STUDY OF FLOWERLEsS PLANTS. $15 
In the second part, the st histology of medicinal plants is 
treated under the various organs, viz., ro ots, stem s, leaves, flowers, 
s 
under the microscope. A great advantage is also obtained ty in ind 
peta the different tissues in faint tints of green, brown, &¢ er 
ach drug a brief account of the botanical origin and mediastad as is 
pin vrith a full description of the physical appearance and 
properties, and an whitey summary of the distinctive histological 
features of each 
he Pirlcroasasinn drawings by M. Bonnet are all that could be 
desired, but the small cuts of the plants or drugs are somewhat 
crude, and in a few instances the names odes these have been 
misplaced ; thus, on p. 245, the leaves of Conyza are labelled 
Digitalis, and vice versa; the na mes white mustard and black 
mustard are similarly transposed, and the figure of “Cigue 
officinale’ is evidently not that of hemlock, since et represents the 
three long pendulous bracts under each partial umbel, characteristic 
of Aithusa Cynapium. The figure of phyllary of Semen ait a 
object under the microscope. With these few exceptions, the wor. 
is well do > a English readers, it has the defect that the 
botanical names used in France are in many cases different from 
those in use Pa “this country, e. g., Chasmanthera palmata H. Bn. for 
calumba; aud some of the drugs, such as turbeth root (Ipomea 
Turpethum R. Br.), are almost unknown in this country. Never- 
theless the work is so clearly ia em and the characteristic features 
of drugs as seen the microscope are so carefully emphasised, 
that it cannot fail to be found exceedingly useful to the student of 
vegetable materia medica E. M. Hotes.
