370 ME. W. H. FLOWER OX THE OSTEOLOGY OF THE SPEEM-WHALE. 



DESCRIPTION OF THE PLATES. 



PLATE LV. 



Skeleton of the Tasmanian Cachalot, as mounted in the Museum of the Koyal 

 College of Sui-geons. Scale ^^. The ribs and pectoral limb of the distant side are 

 omitted for the sake of greater distinctness. The small eleventh rib is almost entirely 

 concealed by the one in front of it. 



It is but due to the long-continued and valuable services rendered to the study 

 of comparative osteology by my namesake, Mr. James Flower, the articulator to the 

 College, whose mechanical skill, combined with extensive and accurate anatomical 

 knowledge, has enabled him to bring the art of mounting skeletons to the greatest 

 degree of perfection yet attained, to mention his name in connexion with this, his 

 greatest work.
