Cancer, unless arrested before it becomes developed, is a fatal disease, and is thought to be contagious (it will be better to separate the infected bird from its companions at once). It always attacks the foot or the bill, which become much swollen. The curative process is to keep the cage constantly clean, so that no particles of dust or dirt may adhere to the scirrhous part, and to bathe it frequently with sweet or olive oil, and wash with lukewarm milk.

"Want of Appetite usually occurs after breeding, moulting, or other sickness: in this case take about equal parts of millet, canary, rape, yellow, and a little hemp-seed, mixed with the same quantity of clean moistened garden loam; knead well together, then dry the composition, cut it up in small pieces, and feed it as required; it will keep a long time.

Scabs on the Head may be best and most easily cured by feeding on light and cooling food, such as lettuce and rape-seed.

Epilepsy is brought on by too rich food. Keep the bird quiet and free from sudden alarms, and feed on lettuce, rape, and canary-seed. Give no hemp-seed for a while ; it is always fatal.

Moulting is always a trying time; it is sometimes dangerous to young birds; it commences when they are from six weeks to two months old, and lasts several weeks. You will observe that the birds lose their natural vivacity, and sit moping about with their heads under their wings, and soon the bottom of the cage will be strewed with the shed feathers. All you have then to do is to keep them quiet, and free from draughts. At this time they require warmth, and as they have little appetite, it is better to give them as much variety in their food as possible, also being careful to crush for them any hard kind of seed like hemp, as they are very weak. A rusty nail or a shred of saffron in the water glass is a useful tonic And if the bird should be attacked with any sort of fit, some authorities recommend dipping its feet in warm water, or dashing a little cold water over it.

Hang them in the sunshine, and give them any nourishing food they may fancy. Let them have a lump of sugar to peck at. Supply them with green food, and keep the floor covered with sand or gravel.

If the moulting proves unusually tedious and distressing to the bird,.it may have some sponge cake soaked in sherry wine; very little wine, and some of the wine might be blown over its feathers.

Diarrhcea. - This is frequently a fatal disease with canaries, as with other cage birds. The bird attacked with it constantly voids a white fluid matter, which causes great inflammation of the rectum. The best remedial measures are as much natural food as possible. A rusty nail placed in the drinking cup, and a little hard-boiled egg, may be given. A piece of chalk may be put between the bars of the cage for the bird to nibble, or some scraped chalk scattered on the floor. If these remedies fail, I have not much faith in anything else. Green food to be omitted.

Constipation is most effectually relieved by green food.

Rupture or Surfeit is not uncommon with improperly fed birds, from their eating too much food, though of nourishing kinds, producing an inflammation of the bowels. Relief is sometimes obtained by a spare diet, with a little salt, alum, or a rusty nail in the drinking vessel; anoint any skin which has become bare with lard.

Accidents. - The best way to accustom a bird to fly, when it is old enough to do so, is to let out a few of those who are quite accustomed to it, and then, having drawn down the blinds, or, still better, closed any muslin curtains, the bird will hop out of its cage peaceably, and when it has once examined the room well, will ware glass sufficiently.

If unfortunate accidents do, however, happen to birds getting loose, I think the best thing that can be done is merely to keep them wrapped up warmly for a day or two, feeding them with egg or milk from a quill, if their heads have been badly bruised, as often happens. Should they meet with a fall or blow so severe as to stun them in their rapid flight, a few moments generally are sufficient to bring them to themselves, and they must be held in the hand or put into a soft cage to recover, as otherwise they begin at once to beat about in a great fright: a little cold water dropped on the head and bill, is the best thing for them; and after such escapades, the cage should be shaded for an hour or two to give the patient a little time to rest, when, if it is not seriously injured, it will soon be again quite comfortable. Obstruction of the Bump Gland. - In every bird there is a gland just above the tail, which secretes the oily substance necessary for oiling the feathers, and preserving them from the effects of rain. As in captivity birds rarely get wet, they sometimes neglect to use this gland, and it swells, dries up, and even ulcerates. The bird sits still, with the tail bent downwards, and frequently pecking at the rough feathers on the affected part. Apply an ointment of unsalted butter and sugar, or enlarge the opening of the gland with a needle; but the latter, though it cure the disease, destroys the gland, and the next moulting season the bird dies for want of the oil to soften the feathers. An ointment to be procured at the druggists' is effectual. It is composed of litharge, white lead, wine, and olive oil.

We have now given a tolerably complete list of the ills and casualties of canary life in a state of confinement, with their appropriate remedies; though we think that, so far as ladies are concerned, the non-doctor.

ing system is the best, as they may be entirely mistaken as to the nature of the disease with which their birds are affected, and give medicine that would take life. With moderate but constant care of their little pets, proper food and cleanliness, they will rarely have to refer to this part of my book. The canary is not a delicate bird by any means; but if properly cared for, will keep in good health and full power of song for many years.

The love of birds, and the increasing number of ladies and gentlemen who possess these little enliveners of the house, has called for this book, which we hope will make bird-keeping as easy as it is delightful.
