is no probability of curing this disease without shaving the head and administering to the 
follicle. 
Or Pine in Sorrentne or THE Brain.—Examination and Description of the hatr of the 
head of a male, aged 60 years, laboring under Softening of the Brain, from the saturation 
of the system by the syphilitic virus—Specimen presented by D. I. Cain, M. D., Charles- 
ton, South Carolina, April, 1852. General appearance, nothing remarkable ; length, about 
four inches; shape, oval, some of them slightly flattened on one of the extremities of 
the conjugate axis; diameter, 31;% 4 of an inch; color, of 20 hairs in the lock, seven are 
dark colored, the remainder are colorless, apparently from age; lustre, considerable ; 
direction, flowing, slightly curled; inclination, no opportunity of examining, but pre- 
sumed, from the shape, to be at an acute angle with the epidermis. (See fig. 81.)

Fracture, abrupt; button, enveloped in a white, cellular substance which extends a 
considerable distance up and down the shaft, and prevents the button from being defined. 
This substance may, however, be rendered transparent or removed by maceration, when 
the button is seen, reduced toa mere knob. The matter removed by maceration imparts to 
the water a milky hue; shaft, cortex squamose; central canal, interrupted; fibres, very 
apparent, when the shaft is crushed; disk, some dark colored throughout, others having a 
minute, white, central spot. 
Remarks.—The part of this hair which is in an abnormal condition is the button and 
posterior termination of the shaft. ‘The former, which in a healthy subject is naked, and 
is the shape of an oil flask and transparent or translucent, im this is covered with the 
white substance above described, and has lost its normal shape and transparency. In the 
white matter of one of these hairs are detected minute, highly colored, either fibres or 
vessels, for they are so small that it is difficult to determine their character with the highest 
powers of the microscope.
