Rule: Divide the sum of the percentages of hydrocarbons and phenols by 1.2, subtract 1 from the quotient, and multiply the remainder by the specific gravity of the dip. The diluted dip will then contain 1.2 per cent of hydrocarbons and phenols and between 0.1 and 0.2 per cent of phenols. Vase III.--When the percentage of phenols is between one-sixth and one-fifth of the sum of the percentages of hydrocarbons and phenols. Rule: Multiply the percentage of phenols by 5, subtract 1 from the product, and multiply the remainder by the specific gravity of the dip. The diluted dip will then contain 0.2 per cent phenols and between 1 and 1.2 per cent hydrocarbons and phenols. Case IV.--When the percentage of phenols is between one-fifth and two-fifths of the sum of the percentages of hydrocarbons and phenols. Rule: .Subtract 1 from the sum of the percentages of hydrocarbons and phenols, and multiply the remainder by the specific gravity of the dip. The diluted dip will then contain 1 per cent hydrocarbons and phenols and between 0.2 per cent and 0.4 per cent of phenols. In each case the result obtained by the rule is the number of parts by volume which may be added to one part by volume of the dip; in practice, the greatest number of gallons of water which may be added to one gallon of dip. It may be stated that if the percentage of phenols is greater than two-fifths of the sum of the percentages of hydrocarbons and phenols, the use of the dip can not be permitted under the regulations, for when diluted until it contains 1 per cent of hydrocarbons plus phenols, the minimum allowed, it will necessarily contain above 0.4 per cent of phenols, which amoun..
