spring, when it gradually ripens, and the gaping scales 

 allow the seeds to escape." 



Order 52nd. CoadunatjE. On this order there is no 

 observation in the lectures, lllicium is added in manu- 

 script to the genera in Gen. PL 



Order 53rd. ScABRiDiE. Here also the lectures are 

 silent. Forskohlea and Tropins are added in the manu- 

 script. 



Order 54th. Miscellanea. Here, although no re- 

 mark is preserved in the lectures, great corrections are 

 made in the manuscript. The genera in the second sec- 

 tion, Poterium and Sanguisorba, are referred to the 35th 

 order, immediately before Agrimonia. Pistia and Lemuel, 

 constituting the 3rd section, are transferred to the 15th 

 order. The six genera which compose the 5th section, 

 are sent to the 4th section of the Holeracea, order 12th. 

 Nympheea and Sarracenia, the only plants of the 6th 

 section, are referred, as already mentioned, first to the 

 27th order, but finally, not without a doubt, to the 1 1th. 

 See the observations under those orders. Cedrela and 

 Swietenia, which make the 7 th section, are removed to the 

 Trihilata, order 23rd. Corrigiola, Limeum and Tele- 

 phium, the 8th and last section, are transferred to the 5th 

 section of the 12th order, Holeracea. No genera there- 

 fore remain in this 54th order, but Reseda, Datisca, Cori- 

 aria, and Empetrum. 



Order 55th. Filices. 



56th. Musci. 



57th. Alga. 



58th. Fungi. 



Nothing occurs here, either in the Pralectiones or the 

 manuscript, to the purpose of our present inquiry, con- 

 cerning the ideas of Linnaeus on natural classification. 

 These orders are all natural, and acknowledged as such 

 by all systematics. His particular observations on each, 

 although in many points curious, are now superseded by
