As an attempt to approach the question of the origin of airborne sulfur, it was intended to make measurements of natural S35 and determine the S32/S34-ratio of sulfur in rain-water. For different reasons the S35 counting had to be omitted, but the S32/S34-ratio, and the sulfur contents of a number of samples of precipitation and sea-water were made.
