PREFACE. 



Were it not that the conventional preface affords a means by which 

 an author may convey his grateful thanks to those from whom he has 

 received advice and assistance, the present book would have been sent 

 forth without the usual preamble. Seeing, however, that the illus- 

 trations form a highly important, helpful, and essential part of the 

 book, it would be worse than ungrateful to neglect this opportunity 

 to thank Mr. James T. Murray for the infinite care he has bestowed 

 upon the drawing of the various dissections. The publishers were 

 indeed fortunate in securing the services of one whose long experience 

 in the illustration of works on anatomy has given him knowledge 

 that, combined with an artistic skill it would be impertinence in me 

 to praise, places him in the forefront of anatomical illustrators. It 

 is greatly to be deplored that the labour difficulties of peace have not 

 spared the workshop of the blockmakers, but have resulted in the 

 frequent neglect of Mr. Murray's instructions respecting the reduction 

 in size of his drawings. Some of the figures have been reduced beyond 

 the carefully determined scale indicated on the originals, and some 

 companion figures have not been reduced to scale. Unfortunately, 

 these errors could have been rectified only at much expense and after 

 long delay. 



To Dr. E. B. Jamieson, of the University of Edinburgh, thanks 

 are due for help in the revision of the footnotes in which the derivation 

 of anatomical terms is indicated. It is hoped that these brief notes 

 will lead the student — and possibly others — to realise that terms are 

 more than mere collections of letters. 



Finally, I cannot abstain from thanks to the publishers, who have 

 been most generous in meeting all suggestions, and in permitting the 

 free use of illustrations.
