She was tenderly nursed by the nuns for an ulcer in the lachrymal gland, which had destroyed the bones of the nose, and produced other horrors of which there is no need to speak.
Not less typical characters are the position of the lachrymal foramen, external to the orbit, and the unossified halves of the lower jaw.
The ridges in the temporal bone unite into a frontal (sagittal) ridge, and the space between the orbits is depressed; a depression is also present on the cheek in front of the lachrymal foramen.
A); the process of the maxilla intervening between the nasal and lachrymal bones; molar teeth large.
In the young of some species the orbit is more enclosed than it is in the adult: the orifice for the lachrymal duct of the eye is placed external to the margin of the orbit: the hollow for the olfactory lobes of the brain is always large.
The lachrymal foramen is just inside, or on the edge, of the orbit, so that one distinctive Lemurine character is lost.
This is placed on the lachrymal bone, and is in fact a lachrymal fossa, such as occurs in other forms.

By gently drawing down the lower eyelid the lower punctum may be seen close to the caruncula; it is the pinhole opening into the lower of the two canaliculi which carry away the tears to the lachrymal sac and duct.
The influence of moral or physical causes increases their secretion, and when the lachrymal ducts do not suffice to carry them off they run over the lids.
If the wall of the lachrymalsac or nasal duct is torn, the patient should be warned not to blow his nose for some days lest air be forced into the tissues and produce emphysema.
The nasal ducts may be injured, obstructing the flow of the tears, and a lachrymal abscess and fistula may eventually form.
When the frontal (nasal) portion of the maxilla is broken, the lachrymal sac and nasal duct may be damaged and the flow of the tears obstructed.
Recurrent enlargement of the parotid and submaxillary glands, as well as of the lachrymal glands, is occasionally met with in adults, and was first described by Mikulicz.
Wounds of the eyelids are liable to be complicated by damage to the lachrymal apparatus, leading to stenosis of the canaliculus and persistent watering of the eye.

The lachrymal bones, two in number, are the smallest and most fragile bones of the face.
The eyes lose their lustre on account of the lachrymal glands refusing to secrete.
Material containing such organisms might get on the conjunctiva and be washed down through the lachrymal canal into the nose.
The Eustachian tubes may be involved, and the inflammation is sometimes propagated along the lachrymal duct.
How are the tears conveyed from the lachrymal gland to the nose?
Ten or twelve small ducts pass from this gland, and open upon the upper eyelid, where they pour upon the conjunctiva the lachrymal fluid, or tears.
It is then imbibed by the puncta lachrymalia, and carried by the lachrymal canals into the lachrymal sac, from which it is passed to the nasal cavities by the nasal ducts.
Ducts leading from the lachrymal gland to the upper eyelid.
The fluid (tears) secreted by the lachrymal gland, is conveyed to the eye by the small ducts before described.
In all instances, the secretion from the lachrymal glands, that sometimes collects at the angle of the eye, should be removed, as it contains saline matter.
What particular duties devolved upon the "lachrymal visitor," I could never clearly ascertain.
We must be sensibly touched to force the lachrymalgland to compress itself, and to spread its liquor on the orbit of the eye; but the will alone is required to laugh.
The lachrymal fluid is ever present, but in such small quantities that it is unnoticed.
Stockham has said: "The testes may be considered analogous to the salivary and lachrymal glands, in which there is no fluid secreted except at the demand of their respective functions.
A drop of the limpid, saline fluid secreted, normally in small amount, by the lachrymal gland, and diffused between the eye and the eyelids to moisten the parts and facilitate their motion.
An enlargement or protrusion of the mucous membrane of the lachrymal passages, or dropsy of the lachrymal sac, dependent upon catarrhal inflammation of the latter.
Ordinarily the secretion passes through the lachrymal duct into the nose, but when it is increased by emotion or other causes, it overflows the lids.
A term applied to a lachrymal gland on the inner side of the orbit of many animals which have a third eyelid, or nictitating membrane.
A cavity or pouch beneath the lower eyelid of most deer and antelope; the lachrymal sinus; larmier.
It is perforated by a prominent =lachrymal foramen= (fig.
The lachrymal canal opens outside the orbit, and the lachrymal forms a considerable part of the side of the face.
They articulate laterally with the lachrymal and palatine, and ventrally with the parasphenoid.
In some Parrots the lachrymal sends back a process which meets the postorbital process of the frontal and completes the orbit.
The most dorsal of these, perforating the lachrymal bone, is the =lachrymal foramen= (fig.
The opening of the lachrymal canal is commonly double and the lachrymal fossa is large in the Cervidae and the Giraffidae except Sivatherium.
The skull has the orbit almost completely shut off from the temporal fossa, and the lachrymal foramen is situated within the orbit.
The lachrymal and jugal form a considerable part of the side of the face; and the orbit though small is complete and prominent.

There is no fear of the conjunctival sac becoming dry after this operation, since there are numerous accessory lachrymal glands (glands of Waldeyer and Krause) opening on to the superior fornix.
At the same time it should be rotated between the finger and thumb, until the inner bony wall of the lachrymal sac is felt.
Normally the lachrymal secretion is largely removed from the conjunctival sac by a process of evaporation.
The nasal bone itself is next removed, together with part of the lachrymal bone and the nasal process of the frontal.
As a rule, patients who have had the lachrymal sac excised do not complain of epiphora, except in a cold wind.
Occasionally this epiphora may be so troublesome that removal of the palpebral portion of the lachrymal gland is desirable for its relief.
Lachrymal abscess is due to an inflammation around the sac-wall through which infection of the cellular tissue has taken place.
Anger would have but one neck for all mankind, love would have but one heart, sorrow but one pair of lachrymal ducts, and pride two bent knees!
The lachrymal glands are small lobular organs, situated at the outer and upper orbit of the eye, and have from six to eight ducts, which open upon the conjunctiva, between the eyelid and its inner fold.
The oily nature of this secretion prevents the tears, when not stimulated by emotion, from overflowing the lachrymal canal.
In old age and in disease, these canals fail to conduct the tears away, and hence the lachrymal lake overflows upon the face.
Thence the tears, washing the eye, run into the lachrymal lake, D, a little basin with a rounded border fitted for their reception.
The eyes receive a larger amount of blood, and the secretion of the lachrymal glands being increased, the fluid overflows, and tears are formed.
Why is the lachrymal secretion of the horse's eye thick and glutinous?
Each prefrontal bone is traversed close to its anterior extremity by the ends of a strong transverse ridge, which then curve round and pass forwards on the lachrymal and maxillary bones, to subside opposite the ninth tooth.
In all there are two short ridges (convergent in young specimens, nearly parallel in old ones) upon the lachrymal bones, which end before reaching the anterior limits of those bones.
