28 TRICHOLOGIA MAMMALIUM; 



lency Governor Johnson. The whole length is one millimeter; diameter, T T of a milli- 

 meter; that of the shaft being T $ T . 



It is easy to remove the button from the end of a shaft, immediately after it is drawn 

 out, when the same appearance, as in Fig. 18, is represented. 



Buttons are often found upon the ends of hairs ihat fall out. Fig. 19 represents one of 

 these, from a hair of the head of His Excellency James Madison, combed out, in his life- 

 time, and presented to us by Mrs. Madison since his death. 



Henle is of opinion, that the difference in appearance is owing to these fallen hairs 

 having arrived at fuller maturity. 



Of Hairs without a Button. From what has been said in regard to the cells seen in the 

 button, it is inferable that the shaft is generated by the button. Nevertheless, we occa- 

 sionally find hairs without a bxitton. 



This subject will be resumed and explained, under title "Follicle." 



Of the Button of the Hair of the Htad of the cylindrical-piled Man. Generally, these 

 buttons are not so regularly shaped as those of the oval-haired species. 



Fig. 21, Nos. 1, 2 and 3, represent the buttons of three of these, all from the heads of 

 pure American Indians, viz: No. 1, is from the head of Bish-e-ki-se-quau, a female, aged 

 30, a pure Sac, a descendant of Black Hawk, sent to us by the Rev. Mr. Symington, of 

 Independence, Missouri. No. 2, is from the head of Tuh-dxih-guh-mah-ke, a male, of 

 about 25, whose father was a pure Ottowa, and his mother a pure Chippewa. Sent by the 

 Rev. Mr. P. Dougherty, of Grand Traverse, Michigan. No. 3, is from the head of South 

 Wind, a male, aged 17, a pure Iowa. Sent by the Rev. Mr. William Hamilton, of St. 

 Joseph's, Missouri. 



It is not pretended that these three buttons furnish the types of all those of the cylin- 

 drical-piled man, but only some examples, selected from those in our cabinet, where the 

 greatest variety in shape may be seen, to show the general outline. 



The button of the pile of the head of the pure eccentrical, elliptical species, comes next 

 under examination. 



Of this pile we have, in our cabinet, one specimen, presented by Dr. Hering, of this 

 city; one from Delaware, and several from the Southern States; but our principal supply 

 is from Africa, obtained through the kindness of our missionaries. 



Fig. 22 represents the button, or hair, of the head of a pure African. 



The buttons, like the hairs of the heads of Hybrids, resemble, sometimes, those of one 

 parent or ancestor, and sometimes those of the other parent or ancestor ; therefore, it would 

 be useless to describe those hairs or buttons. 



Hitherto we have considered the button found upon the hair of the head ; we must next 

 speak of those found upon other parts of the human skin. They comprise the following, 

 viz : 1, the pavilion of the external ear; 2, the eye-brows; 3, the eye-lids; 4, the nasal 

 fossse : 5, the whisker hairs of man; 6, the beard; 7, the arm-pits; 8, the pubes; 9 the 

 limbs, and 10, the downy hairs of the body generally. 



Each of these different varieties are possessed of definite characters, which we will 

 endeavor to point out ; but we warn the reader, in advance, that he must not expect to
