440 COGITATIONES DE SCIENTIA HUMANA. 



[See Cogitationes de JRerum Naturd, x., p. 228. of 

 this volume. These five Cogitationes agree exactly 

 with the copies elsewhere given, with the exception of 

 a very few verbal variations, which I have mentioned 

 in the notes. With regard to the last it is to be 

 observed that, though it follows the 8th Cogitatio 

 without any break, the words Cogitatio 9 a . are not 

 written at the head of it, as in all the preceding; but 

 Cog. 10. is inserted in the margin ; from which I infer 

 that it was not numbered in the original, and that the 

 number 10 was inserted afterwards by the transcriber 

 in reference to the Cogitationes de Rerum Naturd 

 where it stands tenth and last. That it formed part 

 of the present series however, and belonged to this 

 place, may be inferred from the fact that it is imme 

 diately followed by]

 in Natural! Historia jaciuntur ; eaque copiosa et accut 

 rata. Aliunde petita philosophia natat et ventosa est 

 et agitatur et se confundit ; nee ad utilitates humanas 

 et partem activam ducit 1 aut pertingit. Atque ut 

 distinctius loquamur, Historia Naturalis aut non satis 

 investigata aut non satis inspecta duo vitia et veluti 

 morbos aut corruptiones Theoriarum peperit. In al- 

 tero homines ad Sophistae potius, in altero ad Poetse 

 partes accedunt. Qui enim ex vulgaribus observation- 

 ibus theorise principiis concinnatis, reliqua in ingenii 

 discursu et argumentatione ponit, is quamcunque existi- 

 mationem aut fortunam Inventa sua sortiantur, tamen 

 revera ex veterum Sophistarum more et disciplina phi-
