218 Variation and Correlation of the Human Skull 
skulls of which 15 were female and 12 male. Of course depression passes insensibly 
into constriction, but the constriction is so markedly more a female than a male 
character, that for some time one was inclined to consider it might be due to some 
feminine habit of wearing a tight band round the head. 
Depression of the obelion occurs in 19 skulls, of which 12 were female and 
7 male ; flattening of the obelion was noted in one male and a groove of the obelion 
in one male and one female skull. A coronal groove was also recorded in one male 
skull. There were isolated cases of parietal flattening and depression of the one 
or other frontal. A very marked inion was noted in eight cases, naturally the 
male crania having the majority of 5 to 3. 
Plagiocephaly was recorded in five cases, three male and two female, and one of 
the latter is reproduced in Plate XLI. The peculiar shape of forehead which 
may be best described as a " marked infantile type " was found in four crania all 
female ; one of these otherwise normal skulls is depicted in Plate XVII. The great 
length of the English skull is not a little due to the frequency of protuberant 
occiputs*, and these have been especially noted in our second series. It is further 
emphasised by the frequency of almost every degree of bathrocephaly. Fifteen 
bathrocephalic skulls, 9 male and 6 female, were recorded, and an equally high 
percentage was found in our second series. In 7 out of the 1.5 cases, bathrocephaly 
was combined with a more or less numerous system of ossicles in the lambdoid 
suture (Merkel). Plates XLII — XLV give fairly good representations of two 
female (W. 7042 and W. 7059) markedly bathrocephalic skulls. 
A torus occipitalis was noted in 13 skulls, 7 males and 6 females. 
Turning now to the neighbourhood of the foramen magnum a careful exami- 
nation was made of the condyles, and single or paired precondylar eminences 
noted in 14 crania, 5 male and 9 female. One female skull showed a third con- 
dyle with articular facet (W. 170), and one male (W. Ill) had the anterior extremities 
of the condyles united by an osseous bridge. This is illustrated in the sketch 
below as it was found impossible to obtain a satisfactory photograph. 
Plates XL VII and XLVIII illustrate cases of single and bilateral precondylar 
eminences. (Condylus tertiusT) 
Of other peculiarities we may note the rare case of the hamulus lacrim,alis 
reaching the face figured in Plates XLIX and L ; two cases of marked projection 
from hinder margin of external pterygoid plate (W. 85 ^ and W. 86 ?), two of 
the^o?-«s crotaphitico-huccinatorius of Hyrtl (W. 122 ^ and W. 128 $ ), 5 cases of 
single or bilateral pterygospinous bridge, 3 male, 2 female; and isolated cases 
of imperfectly developed mandibular articulation (W. 57 ? ), torus palatinus 
(W. 149 ?, see Plate XXIX), of subdivided foramen ovale (W. l73 (/) and of 
markedly small right jugular foramen (W. 192 (/" ? ?)• 
* Marked occipital projection occurred in four Whitechapel skulls, all four being female. Occipital 
flattening in one female skull.
