Abstract
THE twenty-fifth annual report of this station shows that it continues to be an active instrument in advancing biological teaching and research, sixty students and research workers having occupied the tables during the year. Among the several researches in progress may be mentioned a biometrical investigation of the variation in the shells of the common limpet, which shows that specimens collected near low-water mark are flatter than those taken near high-water mark, and that, contrary to expectation, there was no difference in height between shells obtained from exposed and from more sheltered positions, if taken at the same water-level. Biddulphia sinensis, a diatom from the Far East, which made its appearance in European seas eight years ago, and was recorded from Port Erin in the last report, was found again in quantity and in vigorous condition, in September and October, 1911.
