The dissector's guide, or, Student's companion : illustrated by numerous woodcuts, clearly exhibiting and explaining the dissection of every part of the human body . the impulseof the eye-lids.* The caruncula lachrymalis is a small gland of a reddish color, of theconglomerate kind, supplying sebaceous matter to this part of the eye-lids ; and serving in particular to separate the puncta lachrymalia, and todirect the tears to them while the eye-lids are shut. Minute hairs arefound upon the surface of this body, serving to entangle small objectswhich get into the eye. The lachrymal sac is a receptacle for the tears, and is placed in a fis-sure formed by the os unguis and superior maxillary bone ; the ductus adnasum is a continuation of the sac, and conveys the superfluous tearsinto the nose. * From the diagram on the opposite page, the student may learn how a probeshould be inserted into the ductus ad nasum, viz. by introducing it first in anhorizontal, then in a perpendicular direction, 130 THE DISSECTORS GUIDE.
