    for washing walls, furniture, &c. (a wineglassful to a quart of water), and for soaking soiled infected linen (i in 20). IV.—SULPHUR [Sulphurous Acid Gas]. —For dis- infecting unoccupied rooms. Tightly close windows, ventilators, fireplace, &c., pasting slips of paper over all cracks, and stuffing a sack of chaff or shavings up the chimney. Care must be taken to employ enough sulphur (ij lbs. to each 1,000 cubic feet of space), and, if the room be a long one, the sulphur should be divided into two or more portions. Place roll sulphur (broken into fragments half the size of a walnut) in a tin or iron dish, large enough to hold it all when melted ; place the dish on a brick or other support in an iron pail or common earthenware pan ; pour some water into the bottom of the pan, to receive any melted sulphur which may run over. If the room be a long one, two or more such dishes must be used. The sulphur is then to be ignited (by pouring a little methylated spirit on to it and lighting it), the door closed and sealed externally with slips of pasted paper, and the room left for twelve hours. The room may then be cautiously entered, windows, &c., opened, fire lighted, and the walls, furniture, &c., washed with the dilute perchloride of mercury or carbolic acid solution, or with hot water and carbolic soap. Tins of compressed sulphur dioxide may be used instead of burning crude sulphur (full directions are given on the tins). Sulphur-fumigated goods should not be further dis- infected by steam. v.—CHLORIDE OF LIME [Bleaching Powder].— Must be kept in a dry place. Add i lb. to i gallon of water for sinks, closets, drains, &c. A weak solution (i oz. to i gallon of water) may be used for quickly rinsing soiled linen before it is wrung out in clean water.
