Mr. Higginson stated, that the Natural History 

 Society had also been presented with a stone found at 

 Bremen, evincing footsteps of the Chirotherium, similar to 

 the vestiges discovered at Storeton. Mr. Higginson was

THE PAPER FOR THE EVENING WAS, 



AN ANALYSIS OF DR. PRITCHARD'S RESEARCHES, IN THE 



PHYSICAL HISTORY OF THE INDO EUROPEAN GROUP 



OF NATIONS.— By Dr. Tvrnbvll. 



The Natural History of Mankind forms an interesting 

 subject for investigation, and it has of late years received 

 the careful study which it merits. Dr. Pritchard in his able 

 researches which have added so much to our knowledge of 

 this department of natural History, has, with the view of 

 determining whether there be one or more species of men, 

 adopted two modes of investigation, viz., the analogical 

 founded on the laws of the animal economy, and the histo-

In carrying out the latter mode of investigation, he has
