in the original schedule, but afterwards were distributed in 

 this manner by the copyist. In like wise the M. L. U. of 

 1764 under the Venvis Dione has onlv the usual three authors: 

 RuMPHius, GuALTiEKi and d'Argen VILLE, while' already the 

 Lectures of 1752 have in addition: Olearius, Lister, Historia, 

 and Petiver, that is exactly the full references given in the 

 S. N. ed. 10, 1758, which, therefore, must have been made 

 out and written down at Drottningholm for the M. L. U., 

 but in that work given ouly partially whilst it was beino- 

 prepared for printing. The work of Petiver, of which the 

 only copy accessible to LiNN^US was at Drottningholm as 

 early as in December 1751, is cited for twelve species only 

 in the M. L. U. and the Lectures taken together, but of these 

 twelve quotations one alone refers in both to the same species, 

 the Cyprasa hirundo. Of the remaining ten, four are in the 

 i\l. L. U., 1764, and six in the Lectures, 1752. It cannot 

 well be doubted that these six, all belonging to species in 

 the Queen's Cabinet, were originally inscribed on their rc- 

 spective schedules in the primitive MS, as also, along with 

 them, the very great number of quotations found in the S. N. 

 10, but were simplv omitted when the work was being written 

 out for the press. It would be easy to multiply the instances 

 of the original references having been thus distributed between 

 the difFerent publications. 



From the particulars thus dwelt upon at some length, 

 from the statements of the autobiography and the correspon- 

 dence with Bäck, and from the following facts: first, that 

 the original schedules of the entomological part of the M. L. 

 U. represent the state of the Insect Cabinet up to the end of 

 1752, and not beyond that time; secondly, that the great ge- 

 nerical transformations of the Testacea in comparison to the 

 S. N. of 1748, that appear in the Lectures of the autumn of 

 1752 in close accordance with pencil-notes in the authors 

 own hand no doubt made shortly before, evidentlv are de- 

 rived from the original MS. of the M. L. U., from which the 

 Lectures have received not alone diagnoses, but in some in- 

 stances even entire descriptions verbatim transferred ; and 

 thirdly, that certain references to preceding authors, distri- 

 buted between the different works, must have had their com- 

 mon place of origin in the primitive MS. of the M. L. U., it
