Abstract
IN a recent paper, I. Mackenzie Lamb1 directed attention to the use of polyethylene glycol (‘Carbowax’) for the permanent preservation of algal material for microscopic study. He shows that it is practicable to preserve algae in the dry state embedded in polyethylene glycol and mounted on cards. When a portion is required for study, part of the card is snipped off and soaked in water. The alga then resumes its original state sufficiently well for detailed microscopic examination.
