PREFACE. 
The present Guide has been prepared with the object of being of 
service not only to those who endeavour to learn something from 
a cursory view of the collections on a single visit to the Museum, 
but also to those who desire, by closer study, to acquaint them- 
selves with the general arrangement and the principal features of 
the members of this class of animals. 
In the preparation of the parts relating to the Mammalian 
and Osteological Galleries much assistance has been given by 
Mr. Oldfield Thomas, the Assistant in charge of these collec- 
tions. The portion describing the contents of the Cetacean Gal- 
lery has been written by the Director, Professor Flower, F.R.S.
