of the instrument being parallel to the long axis of the 
bone. 
22. Maximum length of Radius , from the upper border 
of the head of the bone to the extremity of the styloid 
process. 
23. Maximum length of Femur .—The femur is placed on a 
table or flat surface, with its inner aspect downwards, so that 
the tuberosity of the internal condyle and the articulai 
head of the bone rest against the table, the length is 
measured from the lowest point of the under surface of the 
internal condyle to the summit of the head of the bone in a 
direct line. 
24. Maximum length of Tibia .—The central spine is not 
included, the measurement being taken from the highest part 
of the flat surface in front and at the sides of it, to the 
extremity of the internal malleolus. 
Note.— The tape should only be used in measuring Nos. 
5 and 6 ; all the other measurements are to be made with the 
anthropometer.

No. XI.—INTRODUCTION. 
Deductions regarding the comparative physiology of man 
lo be trustworthy require to be based on even more numerous 
observations than anatomical characters. The study of this 
branch of anthropography offers excellent opportunities for 
medical men settled for some time in a country. It is only 
nossible here to give an outline of the direction which such 
studies may take and to indicate some of the observations 
which may be most readily made by the traveller.
