ON THE DATES OF PUBLICATION OF SOWERBY'S "MINERAL 

 CONCHOLOGY" AND "GENERA OF RECENT AND FOSSIL SHELLS." 

 By E. R. Sykes, B.A. 

 Read 8th June, 1906. 

 Recently Mr. Reynell has lent me a little volume containing the back 

 covers of parts 1-108 of the "Mineral Conchology," and since these 

 covers give details of the contents and date of publication of each part 

 it appears that a list might prove of use. One such list has been 

 given by Mous. Renevier,' but it is somewhat difficult of access and 

 does not go so fully into detail as I have been enabled to do. I was 

 somewhat puzzled to find that Mr. Reynell' s set of covers ceased with 

 that of No. lOH, but an inspection of a copy of vol. vii, bound in the 

 parts and lent by Mr. R. B. Newton, readily explains the matter, for 

 after the cover of No. 108 the residue give no details as to the contents 

 of the part. 



I desire to thank Mr. Sherborn for his help, and regret that at 

 present I have not found time to utilize his notes on the dates of issue 

 of the foreign editions of the work.
