VI PREFACE. 



examined. Since that time the Professors of Anatomy in the 

 University, and other naturalists trained in the Edinburgh 

 School, of whom I may especially name Sir John Struthers, 

 have published descriptions and have made collections which 

 have contributed to the growth of the Anatomical Museum. 



The Museum is also much indebted to the late Professor 

 Sir Wyville Thomson and to Sir John Murray for a collection 

 of skulls and skeletons of Cetacea and Piimipedia brought 

 home by H.M.S. Challenger, which have been described in 

 the Zoological Reports of the Expedition. More recently 

 Dr Wm. S. Bruce has generously presented skeletons of the 

 Pinnipedia which he had collected during the voyage of the 

 Scotia in the Antarctic Ocean, examples of which had not 

 previously been in the Museum. Students and young medical 

 graduates of the University who have from time to time 

 taken part in whaling voyages to the Arctic Ocean, more 

 especially Dr Robert Gray, have also contributed specimens 

 of Cetacea and Pinnipedia from that region. 



Preliminary to writing the description of the osteological 

 section I consulted Professor Robinson, the Conservator of 

 the Museum, and with his approval I arranged witli Dr 

 T. B. Johnston, one of the Demonstrators of Anatomy on 

 his staff, to draw up a card list, in which the nature of 

 the specimen and the species and genus to which it belonged 

 were to be noted. I desire to express my indebtedness to 

 Dr Johnston for the assiduity and care which he gave to the 

 execution of this part of the work. In the description of the 

 bones I have availed mj^self, so far as seemed necessary, of 

 the details recorded in my published papers, and it may be 

 stated that the account of the skeleton of Bakenoptera sibhaldi 

 has been drawn up from notes made during my dissection of 

 this animal more than forty years ago, and not previously 

 published. 



As regards the specimens illustrative of the soft parts, 

 which with few exceptions are preserved wet, the descriptions
