advertising his works for sale, which were found in the copy 

 of Hiibner's ''Sammkmg" in the Royal Librarv' at Berlin; 

 Prospectus I\', dated' Augsburg, 6th April, 1809, contains a 

 reference to "Beitraege zur Sammlung Ex. Schmett.,"' stating 

 that tz^'o plates were completed and for sale at 36 kr. a plate ; 

 obviously from this the "Beitraege"' or "'Zutraege.'" as they 

 were later called, were commenced at a much earlier date than 

 that of the title-page to the first century (December 22, 1818; 

 and it seems probable that this date indicates the completion 

 rather than the comnicnccinent 01 the centiiry. especially as 

 Prospectus \, dated 22nd December, 1823, announces two 

 complete centuries of the "Zutraege." as it is now called, for 

 43 fl. 24 kr., and the date on the preface of the second century 

 is 1822. Accepting this evidence as conclusive, Hampson's 

 remarks concerning the incorrectness of Sherborn & Prout's 

 fixation of the dates of the early pages of the "\'erzeichniss" 

 as 1816 and 1818 are fallacious : the text of the "\'er7eichniss" 

 preface distinctly shows that it was written prior to the re- 

 mainder of the work and it is just as distinctly dated Augs- 

 burg, 2ist September, 1816; the fact that he refers by number 

 in the "Verzeichniss" to certain plates of the ■;,'Zutraege" shows 

 that these plates were issued prior to 1816 or 1818. as the case 

 may be. Instead therefore of dating all the plates of the first 

 century of the "Zutraege" 181 8 we must use the dates 1800- 

 1818 and for the second century 1818-1822, the reference to 

 Lycus niphon ( Zutr. 203. 204) on page 74 of the 'A'erzeich- 

 niss," clearly showing (if we accept Sherborn's 'A'erzeichniss'' 

 dates) that the first plate of the second century was ready late 

 in 1818; up to page 160 of the "A'erzeichniss" the latest refer- 

 ence to tlie "Zutraege" I have found is on page 149 to figures 

 213-4 which at least would make 1820 the latest date possible 

 for the first three plates of the second century. 



In the first 16 pages of the "Verzeichniss," for which the 

 date 1816 is claimed, the latest reference to the "Zutraege" is 

 Sicyoiiia apscudcs Hbn. (Zutr. i_ii, 142) ; 2^ out of the 35 

 plates of the first centur}- were therefore published prior to 

 September, i8t6. the first two plates being prior to April, 1809 ;
