born near
Erfurt on the 13th of May 1738. He studied medicine at Erfurt, Halle and
Jena, and in 1761 was entrusted with the superintendence of the military
hospitals connected with the Prussian encampment near Torgau. He published
in 1765 a treatise _De Militum Morbis_, which met with a favourable
reception. In 1768 he became professor of medicine at Jena, whence he
removed in 1773 to Goettingen, and in 1785 to Marburg, where he died of
apoplexy on the 21st of January 1804. Among his pupils were S. T.
Soemmerring and J. F. Blumenbach. Some eighty-four separate treatises are
mentioned as having proceeded from his pen, in addition to numerous papers
scattered through various collections and journals.

BALDINUCCI, FILIPPO (1624-1696), Italian writer on the history of the arts,
was born at Florence. His chief work is entitled _Notizie de' Professori
del Disegno da Cimabue ... (dal 1260 sino al 1670)_, and was first
published in six vols. 4to, 1681-1728. The capital defect of this work is
the attempt to derive all Italian art from the schools of Florence. A good
edition is that by Ranalli (5 vols. 8vo, Florence, 1845-1847). Baldinucci's
whole works were published in fourteen vols. at Milan, 1808-1812.

BALDNESS[1] (technically _alopecia_, from [Greek: alopex], a fox, foxes
often having bald patches on their coats), the result of loss of hair,
particularly on the human scalp. So far as remediable alopecia is
concerned, two forms may be distinguished: one the premature baldness so
commonly seen in young men, due to alopecia seborrhoica, the other alopecia
areata, now regarded as an epidemic disease.

Alopecia seborrhoica is that premature baldness so constantly seen, in
which the condition steadily advances from the forehead backwards, until
only a fringe of hair is left on the head. It is always due to the
underlying disease seborrhoea, and though it progresses steadily if
neglected, is yet very amenable to treatment. The two drugs of greatest
value in this trouble are sulphur and salicylic acid, some eighteen grains
of each added to an ounce of vaseline making a good application. This
should be rubbed well into the scalp daily for a prolonged period. Where
the greasiness is objected to, the following salicylic lotion may be
substituted, though the vaseline application has probably the greater
value: [Rx.] Ac. salicyl. [dr.] i-iv; Ol. ricini [dr.] ii-iv; Ol. ros.
geran. [min.] x; Spt. vini ad [oz.] vi. The head must be frequ
