Abstract
A SURVEY of certain aspects of freshwater biology was arranged by Sections D (Zoology) and K (Botany) of the British Association, under the chairmanship of Dr. E. S. Russell, at Aberdeen on September 10. One of the major problems considered was that of the production of algae in natural waters. These organisms serve as producers of organic materials, and hence their number is a measure of the amount of sub-aqueous life possible. They also serve as indicators of the quality of the water, a field which requires further investigation. On the other hand, their presence may lead to tastes or odours undesirable from a water consumer's point of view and, in waterworks, they may, if abundant, cause considerable expense in filtration.
