This little work is, as its title expresses, a condensed exposition 
of the morphology and physiology of the vegetable world. The 
results of modern research are given briefly, but with consider- 
able clearness. To those entering upon the study of Phytology 
it will prove a useful guide. The absence of an index strikes 
us, however, as a defeCt. 
Invertebrata. By Prof. A. Macalister. (“ The London Science 
Class-Books.”) London : Longmans and Co. 
The little work before us undertakes to furnish, in the brief 
compass of 136 pages, an account of all the invertebrate sec- 
tions of the animal kingdom. From this short space a consi- 
derable portion must further be deducted for the three well- 
written introductory chapters on the nature of animals, their 
vital functions, on nomenclature and classification, mimicry, 
parasitism, distribution in time and space, &c. The difficulties 
of the task, therefore, have not been trifling, and we may con- 
gratulate the author on his success in omitting so little that is 
of primary importance, and in presenting so clear a view of his 
subjeCl under disadvantages so great. 
At the same time we cannot pronounce the work altogether 
unexceptionable. There are certain errors, typographical or 
clerical, which a little care in revision would certainly have ob- 
viated. Thus, on p. 13 1, we find elytrce instead of elytra as the 
plural of elytron. On the same page Agriotes — the coleopterous 
venus whose larvae are so unfavourably known as wireworms — • 
fs misprinted Agrites. On p. 129 we read that “ the larva of 
the common daddy-longlegs feeds on the roots of grass, &c.” 
There are also errors of a more serious nature. On p. 115 is a 
fio-ure showing the structure of an inseCVs body, and said to be 
a dragonfly. Dr. Macalister must be aware that it differs from 
a dragonfly in every part and organ, and agrees much more 
closely with a locust. On p. 131 the reader is told that “the 
destructive Colorado or potato-beetle somewhat resembles the 
ladybird, but is ten-striped, and not spotted.” In a treatise
