mo:' pendent point of the lower articular surface, the body 
or .n of the instrument being parallel to the long axis of 
the bone, while the measurement is made. 
22. Maximum length of Radius , from the upper border of 
the head of the bone to the extremity of the styloid process. 
'*S23. Maxim um len gth 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 articular 
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, at the lower end of the 
bone. 
Note.—T he tape should only be used in measuring 
Nos. 5 and 6 ; all the other measurements are to be made 
with the anthropometer.

B.—PHYSIOLOGICAL OBSERVATIONS. 
No. XL—INTRODUCTION. 
Deductions regarding the comparative physiology of many 
to 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, especially 
to such as are attached to native regiments or hold fixed 
appointments. It is only possible 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.
