stumbling-block for those who are trying to simplify or popu- 
larize the science, gives a brief but coherent and accurate 
account of the processes of nutrition, assimilation and reproduc-

proof of the facts adduced. 
Of course there are a few slips, but the list of errata is small. 
On p. 42 the Spanish moss is called Tillandsia usnoides ; the

and the numerous original wood-cuts, specimens of which we 
are enabled to reproduce, are clear and very useful ; they show 
all that is wanted without being elaborate.
