Country, where he found this boy in a wretched condition ; his parents having been killed 
by the Caffirs. He took the child with him to the Cape, and his business calling him 
again to the interior, he left him in charge of the American Consul. He did not return, 
—and is supposed to have died. ‘The Consul brought him to the United States and placed 
him in the Asylum. He learned to speak English at the Cape, and he has since learned 
to read and write, and appears to possess at least ordinary capacity. His habits are mild 
and his spirit bold and fearless. His features are of an exaggerated negro type, and his 
chest is remarkably full and deep.’”—MS.

Inferences.—We have thus shown, by the pile of the head, that there are three distinct 
species of human beings inhabiting this globe, and whose ancestors have been its inhabi- 
tants for at least from 2,700 to 3,000 years—probably from the first creation of man. 
These are :— 
1. The Man with cylindrical or cylindroidal hair —This pile is straight and lank ; black; 
generally long; pierces the epidermis at an acute angle; has the coloring matter dissemi- 
nated in the cortex and fibres; the scales are few in number, rounded at their anterior 
extremity, and invest closely the shaft. 
2. The Man nith oval or ovoidal hair.—This pile is either flowing or curling; of many 
shades of color; sometimes long; pierces the epidermis at an acute angle; has the coloring 
matter in a central canal; and the scales few in number, rounded at the anterior extremity, 
and invest the shaft closely. 
3. The Man mith eccentrically elliptical or elliptoidal mwool—This pile is crisped and 
frizzled, and sometimes spirally curled; black; short; pierces the epidermis at right 
angles; has the coloring matter disseminated in the cortex and fibres, and the scales nume-
