Dr. S. B. Howell stated to the Section that he preserved the 

 shells and epidermis of the Anodontas in his collection from crack- 

 ing by soaking them well in linseed oil and then rubbing them 

 thoroughly. Mr. John Ford exhibited a specimen of Unio com- 

 planatus, Solander, in splendid preservation, and stated that his 

 method of preserving Unionidge was to immerse the specimens in 

 alcohol for a short time, and afterwards apply oil, rubbing it well 

 into the epidermis. 



Mr. Ford spoke of the discrepancies in different authors in 

 treating of the mode of generation and growth of Argonauta argo. 



Mr. William L. Mactier exhibited Bulimus hcemastomus from 

 Barbadoes, where it appears to be colonized, and stated that the 

 specimens were from the collection of our fellow-member Dr. 

 Samuel Lewis. Dr. L. received an adult specimen together with 

 three eggs over three years ago, and placed the latter in a dry 

 place in his cabinet, not supposing that any vitality remained in 

 them, but was much surprised to discover that within a late pe- 

 riod one of the eggs had hatched. 



Mr. William M. Gabb remarked that this instance of long con- 

 tinued vitality in the eggs of terrestrial mollusks was fully pa- 

 ralleled by a case that had occurred in his own experience ; a 

 number of the eggs of Limax Columbianns had hatched in his 

 own collection fully three years after being placed there. 



Mr. Ralph Tate, of London, was elected a correspondent of 

 the Section.

 Conservator, Treasurer and Publication Committee were read,
