OX THE DATES OF ISSUE OF SOWERBY'S " CONCHOLOGICAL 

 ILLUSTRATIONS, " FROM THE COPY PRESERVED IX THE 

 RADCLIFFE LIBRARY", OXFORD. 



By H. 0. N. Shaw, F.Z.S. 



Read 12th jVarch, 1909. 



The copy of this work in the above Library is incomplete, containing 

 only the first 160 parts out of the total 200. It is probably owing to 

 this fact that the lists printed on small paper have been bound up 

 with the parts to which they belong, as the binders did not see the 

 "Instructions" (issued in part 200) where they were told to omit 

 these said lists. Out of the original 160 parts that I have seen, only 

 106 are dated, but from these in many cases it is possible to fill 

 in some of the lacunae by observing the dates of the parts before 

 and after. 



The first few parts were published weekly ; part 5 is not dated, 

 but part 4 was issued on October 19th, 1832, and part 6 on 

 November 2nd, 1832 ; it is therefore highly probable that part 5 

 was issued on October 26th. In manj^ cases, of course, this is not 

 possible after the weekly issue broke down, as parts were then issued 

 at periods of from two weeks to two months after the preceding one, 

 and in these cases all that can be said, from the knowledge we now 

 possess, is that part . . . was issued between . . . and . . . , the 

 dates of the nearest parts before and after. 



It is to be hoped that owners of copies of this work who have any 

 of the missing dates will publish them, and thus complete the work 

 we have undertaken.
