bone for the right foot, and conversely, and he swore this was true.
Torror also said that if the right foot of a turtle is placed upon the
right foot of a patient suffering from the gout, and conversely, he
will be cured."
Gilbert's discussion of leprosy (_De lepra_, f. 336 d) covers twenty
pages and, according to Sprengel, is "almost the first correct
description of this disease in the Christian West." Freind says this
chapter is copied chiefly _from_ Theodorius of Cervia. See page 3
ante. If, however, I am correct in my conjecture that the Compendium
was written about the year 1240, the copying must have been done _by_
Theodorius, whose "Chirurgia" did not appear until 1266.
Leprosy is defined as a malignant disease due to the dispersion of
black bile throughout the whole body, corrupting both the constitution
(_complexionem_) and the form of its members. Sometimes, too, it
occasions a solution of continuity and the loss of members.
The disease is sometimes congenital, arising from conception during
the menstrual period. For the corrupt blood within the maternal
body, which forms the nourishment of the fetus, leads likewise to the
corruption of the latter. Sometimes the disease is the result of a
corrupt diet, or of foul air, or of the breath or aspect of another
leper. Avicenna tells us that eating fish and milk at the same meal
will occasion the same result. Infected pork and similar articles of
diet may likewise produce the disease. Cohabitation with a woman who
has previously had commerce with a leper may also produce infection.
Among the general symptoms of leprosy Gilbert enumerates a permanent
loss of sensation proceeding from within (_insensibilitas mansive ad
intrinseco veniens_) and affecting particularly the fingers and toes,
more especially the first and the little finger, and extending to
the forearm, the arm or the knees; coldness and formication in the
affected parts; transparency (_luciditas_) of the skin, with the
loss of its natural folds (_crispitudines_), and a look as if tightly
stretched or polished; distortion of the joints of the hands and feet,
the mouth or the nose, and a kind of tickling sensation as if some
living thing were fluttering within the body, the thorax, the arms
or the lips. There is felt also a sensation of motion, which is even
visible also by inspection. Fetor of the br
