Summary. An examination of the various theories put forward to account for the fungicidal action of sulphur when applied, not to the plant or fungus, but to a heated surface, has been carried out by chemical methods, and it is concluded:1 That, since the volatile agent is capable of passing a glass‐wool filter maintained at the temperature of the heated surface, it is gaseous in character. 2 That the removal of the volatile agent by passage through a cooled glass‐wool filter is proof that it is neither sulphur dioxide nor hydrogen sulphide but is elementary sulphur. 3 That the condensation of sulphur volatilised from the heated surface appears sufficient to account for the reactions ascribed to particulate sulphur.
