Dr. N. A. Borodin, curator of fishes at the Museum of Comparative Zoology, will talk this afternoon at 4.30 o'clock on "Anabiosis" in the large lecture hall of the Biological Laboratories on Divinity Avenue. Anabiosis deals with the suspension of life, a subject upon which Borodin has already done considerable experimenting. In his lecture he will describe the recent discoveries along this line which have resulted from his freezing the hardy Alaskan blackfish.
