Vol. xlii.] 20 



Mr. P. F. BuNYARD gave a fascinating exhibition of the 

 eggs of Fratercula arctica mounted over a backoround of 

 black velvet, and with each egg illuminated by a small elec- 

 tric bulb placed in its interior. By this novel and pretty 

 device he was able to bring out the fact that a distinct and 

 strongly pigmented colour-pattern underlay a superficial 

 coating of calcium carbonate.
