MISCELLANEOUS. 



On the Dales of Publication of C. IT. i/aJm and C. L. Koch, ' Die 

 Arctchuiden,' 1831-1840. By C. Uaviks Suerbokn. 



(I'liblislied by periuissiun of tlio Tru3tco3 of the British Museum.) 



TiiKRE are 10 volumes of this work, of which Vols. I.-XV. wore 

 issued ill G part-s each, and Vol. XVL ended at part 4. Each part 

 had an original wrapper, on w'hich were printed the month and year 

 of ])ublicatiun. ^kssrs. Friedliindcr and Son of Berlin have 

 favoiuvd me with the following note : — " 14 Feb., 1!J14. — We have 

 a fine copy of the lO vols., in which the wrappers of the parts are 

 bound up with the volumes ; the dates, however, which are printed 

 on the backs (month and year) are not special to each part, but are 

 the same for several parts. For instance, in Zweiter Band the 

 wrapper of part 1 is altered in writing to 'Zweiter Heft,' w^hile the 

 contents on p. 4 of the wrapper remain the same. It therefore 

 appears to us that the dates on the fourth page of the wrappers are 

 without any value." 



The statement in the last sentence of Messrs. Friedliindcr's letter 

 is, I venture to believe, unduly pessimistic. I have carefully com- 

 pared the data of their copy wnth the records in Wiegmann's 

 ' Archiv ' and those of the British Museum, and find that for all 

 practical purposes, at this distance of time, we can rely on them to a 

 very considerable extent. Unfortunately the British Museum copy 

 has been despoiled of its original wrappers ; but the careful system 

 there in vogue, of pencilling the date of receipt on each part in each 

 ])arcel received, has fortunately preserved data now of the utmost 

 value. These pencil dates of receipt not only show that the dates 

 on the original wrappers are in the main accurate, but they also 

 show that the British Museum received the parts some time before 

 the recorder for Araehnida of Wiegmann's ' Archiv.' For instance, 

 Vols. XIII.-XV. :—
