They are then taken out, the surplus solution removed with dry filter paper, are then quickly weighed, and hung by a wire in widemouthed bottles which contain the soil samples. The wires may be fastened to the corks with sealing wax and a grain of thymol added to [132] the soil to prevent the growth of fungi and bacteria. The bottles are then placed in a compartment maintained at a constant temperature (ice box or tireless cooker) for 24 hr., when the paper is weighed again. If necessary, the experiment may be repeated with a sugar solution of another concentration.
