1. Of the Hairs of the Pavilion of the External Ear and its Button —This pavilion is 
fibro-cartilaginous, thin and expanded. It has five eminences and three depressions, which 
are described in Dungl. Hum. Physi., 1 v., p. 147-8. ‘The hairs upon these parts differ 
somewhat one from another ; they vane length, from three to five-quarters of an inch.

And Le Brun, in giving a painter directions in regard to delineating the passions, places 
the principle expression of the face on the eye-brows. ‘The Chinese bestow great atten-

They are in length from a half to a whole inch, and sometimes even longer. Inclination,

tock, M. D., measure one inch and 2; ; have a diameter of 5}, of an inch; are angular, 
curved ; light brown colored at the posterior extremity, and lght at the apex. This pile 
has generally a diameter of about 71, of an inch. Fig. 25, No. 1, represents one of these 
hairs and buttons, drawn from the brow of a very fat person, where a is a part of the 
shaft, 6 the button, c a part of the follicle, and d a part of the tissue disrupted and drawn 
out with the hair. 
Vidal (‘Traitée de Path., v. 3, p. 579,) says that persons have been known who never 
had any eye-brows, but we have not witnessed this phenomenon. 
3. Of the Eye-Lashes or Hairs of the Eye-Lids, (cilium,) and their Buttons.—Anciently 
the word cilium was applied to the utmost edge of the eye-lid, and the hair issuing 
therefrom. (See Plin. 2 Cels.) It is now confined to the hair. 
It is said that persons have existed who had a double row of eye-lashes, which,

arow. But we have not seen any such persons. According to Goldsmith, man and apes 
are the only animals who have eye-lashes upon both the upper and lower lids of the eye. 
The eye-lashes of the Rhea, or American Ostrich, referred to in Goodrich’s Geography, 
p. 444, are feathers. (See Ante., Chapter 1.) It is generally thought that eye-lashes
