even without fracture, is sometimes remarkable. As a result the 

 vault of a skull may assume extreme steno-dolichocephalic or plagio- 

 cephalic appearance, and the arch of the lower jaw be considerably 

 compressed conditions which could easily deceive the inexperienced. 1 

 Posthumous deformations of the long bones may simulate curvatures; 

 in other parts they are immaterial. 



Deformations caused by disease 2 are most commonly those of rickets, 

 or hydrocephalus. Microcephaly, akromegaly, diffuse osteoporosis, 

 and leontiasis ossea, each represent or may produce marked alterations 

 in the shape, size, weight, and individual features of the skull. But 

 recognition of these conditions when well developed offers no difficulties. 

 The bones of the skeleton may be altered through dwarfism, cretinism, 

 giantism, acromegaly, syphilis, inflammations, tumors, osteomalacia, 

 tuberculosis, and above all, as already mentioned, by rachitis. 



MEASUREMENTS OF THE SKULL 



As for measurements on the living, so for those on the skull, the 

 observer needs a well-lighted place and one where he will be least 

 disturbed. He will need ample table space, which, however, may in 

 part be improvised with boards. He should have at hand a camera, a
