ri'^HE present part concludes the consideration of the Animal and its 
Shell, and I propose to complete the Volume during the present

Index and Glossary. 
The Specific Volume will then be at once proceeded with, and I would 
bespeak the co-operation and help of all interested in the thorough and 
detailed working out of the subject.
