NOTE. 
The principal object in making the following collection has 
been to compare the characters of the Skull in the diiferent 
races of men, and these again with the skulls of the lower animals, 
and especially with reference to the internal capacity of the 
cranium, as indicative of the size of the brain. The Proprietor 
has much pleasure in expressing his acknowledgments, in the 
following pages, to those gentlemen who have aided his researches 
in this department of science, and respectfully invites their further 
aid in extending and completing the series. 
This collection is deposited in the Museum of the Academy of 
Natural Sciences of Philadelphia, where it may be seen, free of 
charge, on the afternoons of Tuesdays and Saturdays throughout 
the year.
