viii Preface. 



foreign to that of our Museum founders — is unfortunately 

 common, namely, that they are collections of mere pathological 

 curiosities, the study of which is something quite different 

 from that of practical Medicine and Surgery. It is needless to 

 say that this is an entire misconception, for a properly arranged 

 Museum obviously offers an insight into the varieties and con-

 which clinical study alone cannot supply. The object held in 

 view, therefore, in classifying, arranging, and describing the 

 specimens for the present Volume, has been to bring them 

 into line with clinical work. This has required so much 

 re-arrangement and re-description of the specimens in the 

 Museum, that the present is essentially a new Catalogue rather 

 than a second edition of the old one.

 Series. The specimens it contains illustrate certain aspects of 

 Hypertrophy and Atrophy, of Inflammation, Degeneration, and 

 Repair, which could not otherwise be so well compared. Every 

 effort, however, has been made to limit it, and it does not 

 include Tumours, for reasons that will be afterwards explained.

 Classes have been formed upon the usual Physiological basis, 

 and are such as " the Skeleton and Organs of Motion," the 

 affections of which occupy the present volume ; also " the Ali- 

 mentary Canal," " the Respiratory System," and others, which 

 will be taken up in a subsequent volume or volumes. 



Within the first Class there have been formed three Divi- 

 sions — i.e. (1) the Bones and Joints; (2) Muscles and Tendons,
