_Symptoms_: Depression, loss of appetite and vomiting. Some dogs, when on a voyage or living on a yacht, the first few days appear very listless and dejected in spirits; and although there may be no sickness, food is refused, and they get very thin and miserable-looking. _Treatment_: It is not a serious matter, as a rule, for the nausea generally soon passes off, and the dog starts to eat; but if it continues more than a couple of days, a small dose of bromide of potassium, say from two[1] to ten grains, may be given in a little water three or four times a day, and the dog encouraged to take Vichy water and milk in equal parts; and some tempting food, as a little chicken and stale bread-crumbs, or stewed rabbit with rice, may be offered. Once the dog commences to eat, he generally quickly regains his former condition. =Seton, How to put in a=: Clip the hair closely over the parts of the skin for about the size of half-a-crown where the needle is to enter the skin, and also where it is to pass out; then wash with warm water and soap, and dry. The needle should be slightly curved and sharp-pointed, and threaded with a piece of half-inch tape, which should be smeared over with a little turpentine ointment for about two inches in the centre, which is the part that is to be left under the skin. _The dog being muzzled_, a fold of skin from an inch and a half to four inches[1] should be well raised between the forefinger and thumb from the muscles underneath; then the point of the needle should be passed quickly through the raised skin where the hair has been removed; then draw the needle right through, and detach the tape. A knot should be tied at each end of the tape, about half an inch from the wounds, to prevent the seton coming out. The ends of the seton must be drawn backwards and forwards twice daily to allow the discharge to escape, and a little turpentine ointment rubbed on the tape every day for three or four days. The wounds must be kept very clean. A seton may be allowed to remain in from one to four weeks. [Illustration: Seton] A seton placed on the back of the neck, running from just behind the back of one ear to the other, is a useful form of counter irritant in cases of chronic epilepsy, also for distemper fits. In cases of general paralysis, when all four legs are affected, a seton placed on either side of the neck, running along the course of the spine, often do good; and so they do when placed in the loins, one on either side of the spine, in paraplegia or paralysis of the hind quarters. In pneumonia a seton may be placed in front of the chest, running from the inside of one shoulder-joint to the other. Troublesome cysts that are difficult to disperse, like those found in the flaps of the ear, may often be cured by running a seton through it, and keeping it there for a few days. A small seton placed in the throat, just in front of the larynx, is useful in cases of chronic cough. =Sexual Excitement=:
