by Professor Grabau, and questions were asked by other members. This 
paper has been published as pp. 45-97, Vol. XIX, No. 3, Part I, in the 
Annals of the Academy. 
Dr. Hovey’s material was from the Pennsylvania Railroad Co.’s tunnel. 
A profile of the Hudson River gorge as indicated by the borings on the 
tunnel line was exhibited. The slightly shallower nature of this channel as 
compared to that determined by the McAdoo tunnel borings gave rise to 
considerable discussion. 
Professor Grabau exhibited and explained two charts showing studies of 
probable early Paleozoic distribution of continents and ocean basins and 
borders. 
The Section then adjourned.

SECTION OF BIOLOGY. 
March 8, 1909. 
Section met at 8:15 P. M., Professor Bashford Dean presiding in the 
absence of Vice-President Chapman. 
The minutes of the last meeting of the Section were read and apjuroved. 
The following programme was then offered: 
W. K. Gregory, Genetic Relations of the Insectivora to other 
Orders of Mammals. 
Max Morse, The Harpswell Biological Laboratory. 
Amadeus W. Grabau, Early Developmental Stages in Recent and 
Fossil Corals. 
A communication from Dr. L. Hussakof was read, in regard to his 
application for a grant of 8100 from the Newberry Fund to be used in 
connection with his studies on fossil fishes while abroad. Upon motion of

Mr. Gregory reviewed some of the general stages in the evolution of the 
lower mammals in order to introduce the subject of the genetic relations of 
the Insectivores. The first stage, lying below the limits of the class Mam¬ 
malia, is represented by the higher Theriodont reptiles from the Permian
