ornamented shell of the Argonaut among the Acetabulifera 

 closely resembles in its waving lines and projections the shell 

 of the Ammonites. The want of a division into distinct 

 chambers in the Argonaut shell presents no obstacle to the 

 association, as there are other genera of this class with cham- 

 bered shells. The Ammonites are geologically later than the 

 Nautiloids, and thus the specimen exhibited is only another 

 illustration of the law of correspondence between geological 

 succession and order of position among living species. 



Professor Bowen read a sketch of a Memoir, entitled " Some 

 Remarks on the Meaning and Proper Application in Science 

 of the Terms, A General Fact, A General Law, A Cause." 



Professor Levering and Dr. B. A. Gould, Jr. criticised Mr. 

 Bowen's use, in illustration of his views, of the term attrac- 

 tioji, as understood in astronomical science. 



Professor Lovering announced that the first part of the 

 sixth volume of the Memoirs was ready for distribution to 

 the Fellows.
