(ii) Ossicles and Wormian Bones. 
Ossicles of the bregma were recorded in 4 cases, 2 male and 2 female, and 1 
case (associated with bathrocephaly) is depicted in Plate XXXII. Ossicles of the 
lambda occurred in 11 cases, 4 male and 7 female ; cases of single and double ossicle 
of the lambda are reproduced in Plates XXXIII and XXXIV. Ossicles of the 
asterion occurred in 2 iemale and 1 male case, and of the pterion in 13 cases, 6 male 
and 7 female. There was one case of a frontosphenoidal ossicle (W. 212 </), 1 case 
of ossicles in the parietal notches of temporals (W. 7061 $ ) and 1 case of ossicles 
between occipital, parietal and mastoid (W. 31 (/)• Ossicles were recorded in the 
coronal suture in 3 cases, all male ; in the sagittal suture, in 2 male and 2 female 
cases; in the lambdoid suture in 29 cases, of which 13 were male and 16 female; 
the lambdoid suture had a very irregular line* in the male skull W. 76; in the 
squamous suture there were 2 male and 2 female cases of ossicles and 1 case 
(W. 7109 </) of ossicles in the parietomastoid suture. On the whole upwards of 75 
cases of ossicles were noted, 37 male and 38 female. We may therefore say that 
slightly more than 25 per cent, of English skulls have one or more anomalous 
ossicles. 
(iii) Anomalies of the Sutures. 
Twenty-four skulls were metopic, or a persistent frontal suture was found in 9 
male and 15 female skulls. The mean breadth and minimum forehead breadth of
