_Prussic Acid._--Affusions of water over the cervical vertebræ. Cause the gas from chlorine water to be inhaled. Give from twenty to forty drops of Labbaraque's solution largely diluted, also coffee. _Strychnine._--Cause vomiting. Give ether or chloroform by inhalation, and chloral internally. Insufflate the lungs. _Tartar Emetic._--If there is vomiting, favor it by giving whites of eggs with water in large quantities, then give infusion of gall or oak bark. If vomiting is not free, use the stomach-pump. _Venomous Bites_, Serpents.--Apply a moderately tight ligature above the bite. Wash the wound freely with warm water to encourage bleeding, then cauterize thoroughly. Afterwards apply lint dipped in equal parts of olive-oil and spirits hartshorn. Internally give freely of alcoholic stimulants, with liquid ammonia, largely diluted. _Rabid Dogs._--Apply ligature as above described, wash the wound thoroughly with warm water, and cauterize immediately with nitric acid or lunar caustic, leaving no part of the wound untouched. HOUSE-CLEANING. Do not clean but one room at a time, as it is a bad plan to have the whole house in confusion at once. It is best to commence with the attic. Before beginning on your spring cleaning, remove the curtains, all the movable furniture, and the carpets. With a broom and dust-pan remove all dust from the floor. Then with a wall-brush thoroughly sweep and dust the ceiling and side-walls, window and door frames, pictures and chandeliers. Then go over the floor again, removing the dust that has fallen from the ceiling and walls. Then proceed to wash all the paint in the room. If it be white paint, use whiting or such other preparations as are recommended for the purpose in the subsequent pages. If it be varnished, or in imitation of oak or walnut, wipe with a cloth dipped in milk-warm water. If the wood work in the room be of unvarnished walnut or oak, wipe it off first, and then oil it, rubbing in the oil well. Then with a soft flannel rag and a cake of sapolio clean every piece of marble in the room. Next wipe the mirrors carefully with a flannel rag, wrung out of warm water and dipped in a little whiting, or you may rub a little silver soap on the rag. The gilding must be merely dusted, as the least dampness or a drop of water will injure it. The windows (sash and all) must then be washed in soap and water, with a common brush such as is used for washing paint. A little soda dissolved in the water will improve the appearance of the windows. It is unnecessary to use such a quantity of soap and water as to splash everything around. After being washed, the windows should be polished with newspapers. Except in a general house-cleaning, windows may be cleaned by the directions given above for mirrors.
