All that can be done in a fit of epilepsy is to prevent the patient from injuring himself; especially put something in his mouth to keep him from biting his tongue. A cork, a piece of India rubber, or even a tightly- rolled handkerchief, placed between the teeth will answer this purpose. Give the sufferer fresh air; loosen his clothing, and place him in a comfortable position. Epilepsy may be due to various causes,--improper diet, overexcitement, etc. Consult with a physician, and study to avoid the occasion. CONCUSSION OF THE BRAIN generally arises from some contusion of the head, from violent blows, or from a shock received by the whole body in consequence of falling from a height. In any case of injury to the head where insensibility ensues, a doctor should be called at once. Remove the patient to a quiet room; loosen his clothing; strive to restore circulation by gentle friction, using the hand or a cloth for this purpose; apply cold water to the head, and, if the patient's body be cold and his skin clammy, put hot bottles at his feet. Ammonia may be cautiously held to the nose. Beyond this, it is not safe for a non- professional to go, in case of a severe injury to the head. Concussion is more or less serious, according to the injury which the brain has sustained; but even in slight cases, when a temporary dizziness appears to be the only result, careful treatment should be observed both at the time of the injury and afterward. Cases of head injury are often more grave in their consequences than in their immediate symptoms. Sometimes the patient appears to be getting better when really he is worse. Rest and quiet should be observed for several weeks after an accident which has in any way affected the brain. TOOTHACHE AND EARACHE.--Insert in the hollow tooth cotton wet with laudanum, spirits of camphor, or chloroform. When the nerve is exposed, wet it with creosote or carbolic acid. Hot cloths or a hot brick wrapped in cloth and held to the face will often relieve the toothache. In a similar manner treat the ear, wetting the cloth in hot water, and letting the vapor pass into the ear. CHOKING.--Ordinarily a smart blow between the shoulders, causing a compression of the chest and a sudden expulsion of the air from the lungs, will throw out the offending substance. If the person can swallow, and the object be small, give plenty of bread or potato, and water to wash it down. Press upon the tongue with a spoon, when, perhaps, you may see the object, and draw it out with your thumb and finger, or a blunt pair of scissors. If neither of these remedies avail, give an emetic of syrup of ipecac or mustard and warm water.
