It is clear from this that for a precise comparison No. 1 

 must be left out entirely. The two others, however, pre- 

 viously mentioned, viz., that of the hybrid (No. 316) from 

 the Davis collection and that of the child marked Sinhalese 

 No. 3 from mine, very decidedly approach the Tamil type. 

 They coincide so exactly with one another that the suspicion 

 of the child's skull being really a Tamil skull, or at least a 

 hybrid, grows upon me strongly. The figures for these are 

 the following : —

Contrasted with the Tamils proper the brow here recedes 

 somewhat, whilst the occiput and parietal portions are more 

 developed, and owing to this all the Tamil relations are a 

 little changed.
