72 STUDY OF NATURAL HISTORY. é 
No additions had been made to the natural history 
of Sweden, since the publication of the delightful 
Fauna of that country by Linneus ; but, in 1798, G. 
Paykull*, oneof the ministers of the king, commenced 
an elaborate work on the coleopterous insects of his 
native country, which extended to three. volumes. 
The last name we shall mention of this entomo- 
logical era, is that of Laspeyres, who has most 
beautifully and ably illustrated and described the 
European Sesi@, in a work which must long remain 
a model for future monographers.+ Finally, we may 
here mention Mr. Dillwyn’s t Conchological work, 
which, like that of Villers in regard to insects, is an 
attempt to notice all the species of recent shells to 
the Linnean genera. 
(30.) We have now brought the series of Linnzan 
writers to a close, with the exception of one, whose 
laborious and voluminous work seemed necessary to 
convince the strict adherents to this school, of the 
absolute necessity of a reform in systematic arrange- 
ment; and that it was utterly impossible any longer to 
delay those improvements which Linneus, by his own 
example, had so forcibly inculecated. These truths 
were forced upon the conviction of the most preju-
