On the Dates of Publication op J. D. Wilhelm Hartmann's 

 " Erd- und SiJsswASSER-GASTEROPODEN," 8vo, St. Galleu, 1840. {Read 

 8th December, 1905.) — Some uncertainty has always been felt concerning 

 the exact dates of publication of the various parts of this important work. 

 Eeviews of the first seven parts, however, appeared in Isis, which, 

 allowing for the obvious misprint with respect to parts 3 and 4, enables 

 us approximately to fix their dates, while there need be no hesitation 

 about accepting the date of the concluding part of the work as given in 

 Engelmann's " Bibliotheca Historico-Naturalis," p. 446 (1846).

 baden (C. W. Kreidel), 1870-75. {Read 12th January, 1906.)— Owing to 

 the infatuated objection of binders to the preservation of wrappers, the 

 exact dates of publication of the several parts of tiiis work, a matter of 

 the utmost importance to specialists on account of the number of new 

 genera and species involved, have not been ascertainable from an 

 inspection of any of the copies open to us. Nor, with the exception of 

 MM. DoUfus & Ramond, to whose work Mr. R. B. Newton has drawn my 

 attention, have any of the bibliographers given the contents of the parts.
