however, given a consensus of the two classifications of Phanerogams, which 
will he of material service to the student. He has also substituted Prof. 
Sachs’ classification of Thallophytes for that given by the author. We notice 
that the composite Algo-fungal nature of the Lichens is here accepted as 
proved. The woodcut illustrations are excellent throughout the whole book. 
ZOOLOGICAL CLASSIFICATION.* 
W E are very glad to see that Mr. Pascoe’s little handbook of systematic 
Zoology, the first appearance of which we noticed in April, 1877, has 
been so successful as to cause him to bring out a second and greatly enlarged 
edition of it. The general plan of the work continues the same, but the 
author has modified the classification here and there in accordance with trea- 
tises published during the last four years, and he has added greatly to the 
statements of the opinions of different authors on the classification and value 
of various groups, thus making his book, which is still small enough to be a 
most convenient pocket-companion, an exceedingly valuable compendium of 
Zoology. The glossary of zoological, anatomical, and physiological terms, 
which the author has appended to the book, and which, in general, will 
be found useful, is certainly in some points not so good as it ought to be, 
some of the definitions being unsatisfactory, or even absolutely erroneous. 
In all other respects we can only endorse the opinions expressed in our 
former notice of this book. The author has evidently bestowed immense 
labour on its preparation, and while we admit that there are portions of the 
work which are fairly open to criticism, it would be ungracious to point out 
small defects when the general result is so excellent. 
THE MOUND-BUILDEKS.t 
M UCH has been written by American archaeologists on the subject of those 
mysterious earth-mounds which are abundantly scattered through the 
valleys of the Mississippi and the Ohio. Mr. MacLean has done useful work 
in concentrating the literature of the mounds so as to bring its essence 
within compass of a small octavo volume. Those readers who have not the 
opportunity of procuring, or the time for reading, the larger works on Ameri- 
can archaeology, will find in this little book a popular summary of what is 
known about the mounds and their contents. The implements in stone and
