5549. The cranium of a Hindoo child, marked two years and a half, but smaller and 

 perhaps somewhat younger than the preceding. 



The deciduous teeth have been acquired. The left exoccipital is distinct ; the right is par- 

 tially confluent with the superoccipital. The vacuity between the tympanic and petrosal is 

 more filled up than in the previous skull. The mastoid processes are less developed. The 

 maxillo-premaxillary sutures on the palate extend to the alveoli of the canine teeth. 



Purchased. 



5550. The cranium of a Hindoo child, marked two years. 



The deciduous teeth have been acquired. The exoccipitals have coalesced with the super- 

 occipital, but not with the basioccipital. The petrotympanic vacuity extends to the under 

 part of the meatus auditorius externus. 



Purchased. 



In the foregoing skulls of immature Hindoos (Nos. 5546 to 5550), it is interesting to remark 

 that the alisphenoids have attained, or nearly attained, their mature proportions, whilst the squamosals 

 and malars participate in the inferiority of size of the facial bones which accords with the nonage of 

 the individual. 



5551. The cranium of a Hindoo child, with the deciduous dentition; the first per- 

 manent molars are not fully in place. 



This is stated to have been from an idiot. As compared with No. 5550, the cranium is 

 considerably shorter in proportion to its breadth and height. The forehead presents a simi- 

 larity of form, indicating an equal development of the anterior lobes of the cerebrum, but the 

 parietals are much shorter, and the superoccipital is bent almost vertically upwards from 

 within a short distance of the foramen magnum, which is preternaturally near the back 

 boundary of the basis cranii. The hinder part of this cranium is also unsymmetrically dis- 

 torted. 



Presented by Dr. G. M. Paterson. 



5552. The cranium of a female Hindoo, native of Rajpootana. 



It corresponds in general form with No. 5545. The paroccipital tubercles are denned. 



Presented by Dr. G. M. Paterson. 



5553. The cranium of a young Hindoo, native of Bengal. 



The permanent canines and second true molars were coming into place : the last deciduous 

 molar, left side, is not shed. It presents the usual Hindoo form, with an unsymmetrical 

 occiput. The paroccipital tubercles are defined. The maxillo-premaxillary sutures on the 

 palate extend to the interspace between the canine and incisive sockets. 



Purchased.
