to describe every species of this interesting class of animals, ascer= 
tained to inhabit the British Islands. The first part of the volume 
is devoted to the History of Zoophytology, and to details on the 
Structure, Physiology, and Classification of Zoophytes; and the 
second contains the description of the species. The Publisher 
flatters himself, that this volume will not only be an acceptable one 
to Scientific Naturalists, but to all those who, through various 
channels, have heard of the discoveries relating to this class of 
beings.

“ Externally and internally this is a very elegant volume—a feast to the 
eye and to the mind; rich indeed has been the treat it has afforded us. One 
has only to read the Preface to be convinced that the Work is by a person of 
learning, and science, and taste; of acute and patient observation, and of a 
truly elegant and well-furnished mind. He is already well known in the 
scientific world, but this work will greatly increase his fame.’”— Scottish 
Guardian, Oct. 1838. 
In the Press. 
DR JOHNSTON is preparing for the Press a * HISTORY 
OF THE BRITISH SPONGES AND CORALLINES,” tobe 
printed and illustrated in the same style as his History of the British 
Zoophytes, to which this new work may be considered as a Supplement, 
and as completing his original design. It will contain a very full ac- 
count of all that has been hitherto written on the subject ; and an origi- 
nal figure of every species and remarkable variety will begiven. Dy 
Johnston intends, at the same time, to avail himself of this oppor- 
tunity of adding many new figures of Zoophytes, contributed by his 
friends, and acquired by himself, since the volume on British Zoo- 
phytes was published.
