[Footnote 2: _Haemopsis paludum_. In size the cattle leech of Ceylon is
somewhat larger than the medicinal leech of Europe: in colour it is of a
uniform brown without bands, unless a rufous margin may be so
considered. It has dark striae. The body is somewhat rounded, flat when
swimming, and composed of rather more than ninety rings. The greatest
dimension is a little in advance of the anal sucker; the body thence
tapers to the other extremity, which ends in an upper lip projecting
considerably beyond the mouth. The eyes, ten in number, are disposed as
in the common leech. The mouth is oval, the biting apparatus with
difficulty seen, and the teeth not very numerous. The bite is so little
acute that the moment of attachment, and the incision of the membrane is
scarcely perceived by the sufferer from its attack.]

[Footnote 3: Even men, when stooping to drink at a pool, are not safe
from the assault of the cattle leeches. They cannot penetrate the human
skin, but the delicate membrane of the mucous passages is easily
ruptured by their serrated jaws. Instances have come to my knowledge of
Europeans into whose nostrils they had gained admission and caused
serious disturbance.]
