OR, A TREATISE ON PILE. 97 
i 
So far as our researches have enabled us to ascertain, the following is the first micro- 
scopic examination and description of these hairs:— 
No. 1 Examination and Description of Hairs from Ovaries. Name and description of 
the person from whom it came unknown.—Specimen presented by Prof. Paul B. Goddard, 
M. D., of Philadelphia. (See fiz. 33.) 
Length, 33 inches; shape, cylindroidal; diameter, ;1; by 54, of an inch; color, pale 
reddish-brown; dark brown; not lustrous; direction, slightly flowing, with a tendency to 
a stiff curl; inclination, unknown; ductility, with 870 grains one inch stretched 2, of an 
inch, elasticity entire; tenacity, broke with 1,000 grains; button, a mere swelling of the 
posterior extremity of the shaft; sheath, length, 2; of an inch; diameter, >; white, 
opaque, investing closelythe shaft; follicle, had none to examine; shaft, partially injured in 
places, as if it had been acted upon by some corrosive substance; intermediate fibres, 
(exhibited when a hair is crushed,) coarse; one of them measured 55,5 part of an inch; 
a darker colored hair, when crushed, showed a light-colored cortex and white intermediate 
fibres; apex, rounded; none furcated; disks, uniformly colored; no central canal dis- 
covered. 
In general outward appearance this hair resembles that of the head of the oval-haired species ; 
but it differs from it in its deficiency of ductility, in its cylindroidal shape, in its being injured 
in places in the shaft as if corroded, in the coloring matter being in the cortex, and in the 
absence of a central canal. 
No. 2. Examination and Description of Huitr of an Ovary.—Name and description of 
the person from whom it came unknown. Specimen presented by Prof. Horner, M.D, 
of Philadelphia. 
Length, from 13 to 2 inches; shape, cylindrical; diameters, one ;3;, another 54;, and 
another still, 4, of an inch; color, generally very light, no lustre; direction, crisped ; 
inclination, unknown; ductility, with 190 grains stretched 1; of an inch, elasticity entire ; 
tenacity, broke with 893 grains; button, sheath, and follicle, had none to examine; shaft, 
deficient in uniformity, thinly covered in places by a white opaque substance ; scales on 
the cortex very apparent, rounded and adhereing closely to the shaft; one hair, which 
was of rather a darker shade than the rest, notched as if it was corroded. Upon being 
rolled between two pieces of glass the scales disengage; being crushed, the cortex splits 
transversely, exhibiting the intermediate fibres, which are white and fine; one of them 
measures the ;=4,, part of an inch; apex, sometimes pointed, and at others abrupt, none 
fureated; disk, uniform color; no central canal perceptible. ‘The general appearance is 
that of the hair of the pubis of the oval-haired species. With this lock was a mass of 
tangled fibres of the size of '; of an inch, so much interlaced as to render it impossible to 
ascertain the length, but with various diameters from 7,55 to sj), of an inch, some flat 
and others rounded, all white and opaque but one, and that is blwe.* The peculiarities of 
this hair are its deficiency in ductility, its cylindrical shape, its notched appearance, its 
deficiency in a central canal, and the blue color of the fibre above mentioned. 
* We found a similar colored fibre among the hair of John Dennis Garwood, which grew after death.
