Two donations were made in 1853 : one by Mr. E. L. Layard of

 formed by Dr. LyaU during the voyage of H.M.S. ' Plumper ' in the 

 Northern Pacific Ocean. In the same year a collection made by 

 Mr. T. Ayres in Natal was acquired.

 the Collection ; but in 1863 Mr. J. K. Lord presented the specimens 

 he had taken in the Rocky Mountains and British Columbia, while 

 attached to the North American Boundary Commission, and in the 

 same year a valuable collection was received from Mr. Bernard E.. 

 Boss, from the Saskatchewan and Mackenzie Eiver Districts of 

 Canada.

 of Swedish eggs. 



In 1876, a particularly fine collection of eggs, procured by the 

 Eev. A. E. Eaton in Kerguelen Island during the ' Transit of Venus ' 

 Expedition, was presented to the Trustees by the Royal Society.
