will bear in mind that a lesion is the cause o f functions being
deranged, there will be no trouble in comprehending the fol­

McFarland:—The structural changes wrought by disease are
known as lesions. They may be initial or primary; secondary
or tertiary. The lesions caused by physical agencies are said to
be traumatic and vary with the nature of the force.

Traumatic:—Pertaining to or caused by a wound or injury.
Traumatic fever is a febrile phenomena following a wound.
Produced by wounds; as, traumatic tetanus.

Gould:—An injury, wound or morbid structural change. Dis­
charging lesion:—A brain lesion that causes sudden discharge
of nervous motor impulses. Focal lesion:—A circumscribed
lesion in the nervous system, giving rise to distinctive and local­
izing symptoms. Molecular lesion:—A very fine lesion, not dis­
cerned by the microscope or discoverable by chemistry, but caus­
ing loss or excess of functional activity and attributed to alter­
ation of the molecular equilibrium of that part. Irritative
lesion:—A lesion in the nervous system exciting the functions
of the part wherein it is situated.

Dorland:—Any hurt, wound or local degeneration. Depres­
sive lesion:— One that causes diminution of functional activity.
Destructive lesion:— One which leads to the obliteration of an
organ or the abolishment of its functions. Functional lesion:—
One which leads to no obvious or discoverable change of struc­
ture, but which causes disturbance of function. Indiscriminate
lesion:—A lesion affecting distinct parts or systems of the body.
Irritative lesion:— One which stimulates the functions of the
part where it is situated. Local lesion:— One in the nervous
system giving origin to distinctive local symptoms.

These lesions give origin to distinct local symptoms named
disease. They excite functional activity—disease. They cause
loss or excess of functions—disease. They stimulate, diminish
or abolish f'lmotions, which is but disease.

Webster:—Primary syphilis, the initial stage of syphilis, in­
cluding the period from the development of the original lesion
or chancre to the first manifestations of symptoms.

Dorland:— Primary syphilis in its first stage; the primary
lesion ( chancre) usually appears between ten and forty days
after infection.

G ould:—The earliest lesion o f acquired syphilis is the chancre.
Second in the order of time or development, as the secondary
lesions of syphilis.
Dunglison:— Syphilis generally makes its first appearance by
a hard chancre, the latter being known as the primary or initial
lesion. In the second stage— secondary syphilis—constitutional
symptoms are developed, as exhibited in lesions of the skin and
