330 [Dec. 1847. 



Dr. Morton made some remarks on an Indian cranium of 

 singular form found near Richmond, on the Delaware; and 

 also on a Chenook infant mummy. The cranium is interest- 

 ing on account of its locality, and from its having the atlas 

 vertebra continuous with the occipital bone. No trace of 

 suture is visible ; although the skull has pertained to an indi- 

 vidual not exceeding 25 years of age. 



The Chenook mummy is from the Straits of Fuca ; the 

 head is artificially compressed in a very remarkable manner, 

 according to the custom of these people.
