 A correct abstract (not prepared by us, and all that was pub- 

 lished by the Society) of an elaborate memoir by the writers, 



In the discussion which followed the reading of it, Prof. Ramsay 

 stated he ' ' had been struck long ago by the organic appearance 

 of the structure now regarded as Eozoon. He had also felt a 

 difficulty in accounting for the existence of large masses of 

 limestone, except by the operation of organisms living in the 

 sea, in which such deposits had been formed. He could not 

 imagine the sea-water so overcharged with calcareous matter 

 as spontaneously to deposit limestone." 



Mr. Parker, Prof. T. R. Jones, Dr. Duncan, and Dr. Carpenter 

 made some remarks, all favourable to eozoonism.

The beds of serpentine limestone in the Laurentian system of 

 Canada " are found in many parts to contain masses of con- 

 siderable size, but usually o indeterminable form, disposed 

 after the manner of an ancient coral reef, and consisting of 

 alternating layers (frequently numbering more than fifty) of 

 carbonate of lime and serpentine (silicate of magnesia) "
