Description of the Laboratory of the Marine 

 Biological Association at Plymouth. 



By 

 liValter Heape, m.A. 



The Laboratory which is now in the course of erection at 

 Plymouth for the Marine Biological Association^ is situated 

 between the south wall of the " Citadel " and the Sound, at 

 a height of 95 feet above the level of the sea. The site, 

 which has been granted to the Association by the War 

 Office, occupies the whole length of King Charles's Curtain, 

 265 feet, and extends southwards from the Citadel wall 

 240 ft., giving a surface of, say, 63,600 feet. 



A road lies between this plot of land and the sea, and 

 private access to a small section of the seaboard is provided 

 for by means of a tunnel 7 ft. 6 in. high and 6 ft. 6 in. 

 wide, which leads from the area surrounding the cellars, 

 beneath the road, to the rocks below. 



The building {vide Frontispiece) is placed 90 feet from the 

 wall of the Citadel, and is about 60 yards from high-water 

 mark. It is in the form of two blocks, which are each 34 

 ft. 6 in. long by 42 ft. wide and three stories high (40 ft.), 

 and a central connecting portion 70 ft. long by 34 ft. 6 in. 

 broad and two stories high (30 ft.). The east, south, and 

 west fronts are built entirely of dressed limestone, which 

 has been excavated on the spot ; but on the north front 

 the window- and door-dressings are of brick. 



The roof of the central portion is peaked and covered 

 with slate ; that of the two blocks is flat and covered with 

 lead. 



Below the western block cellars have been excavated 

 (Plate III) 14 ft. deep, surrounded by an area 6 ft. 6 in. wide
