| We are of the opinion that the extra fatty oil will be more beneficial in every way. It is our firm conviction that the oil we are putting forward will effectually replace Castrol; inasmuch, as it possesses greater lubricating properties, and will not split as Castor Oil does after running a few hours. We await with interest the result of your further test, and assure you of our prompt attention to your instructions. We are, dear Sirs, Yours faithfully, W. B.
