 Indogermanischer Sprachstamm in the Allgem. Encyklopadie of Ersch and 

 Gruber, Sect. ii. Thrxviii. S. 1-112.) Investigations on language in general, 

 as touching upon the fundamental relations of thought, are, however, to be 

 found in Aristotle, where he develops the connection of categories with 

 grammatical relations. See the luminous statement of this comparison in 

 Adolf Treudelenburg's histor. Beitragen zur Philosophic, 1846, Th. i. S.

 xvi. p. 739). In this passage, in conjunction with the Chaldean astronomers, 

 four Chaldean mathematicians are cited by name. This circumstance is 

 of the greater historical importance, because Ptolemy always designates the 

 observers of the heavenly bodies by the collective name of Xa\5coi, as if the 

 Babylonish observations were only made " collegiately" (Ideler, Handbuch der 

 Chronologic, Bd. i. 1825, S. 198).

 218. When doubts are raised respecting the fact of Callisthenes having sent 

 astronomical observations from Babylon to Greece, on the ground of "no 

 trace of these observations of a Chaldean priestly caste being found in the 

 writings of Aristotle," (Delambre, Hist, de 1'Astron. anc. T. i. p. 308), it is 

 forgotten that Aristotle, where he speaks (De Coelo, lib. ii. cap. 12), of anoccul- 

 tation of Mars by the moon observed by himself, expressly adds, that "similar 

 observations had been made for many years on the other planets by the Egyp- 

 tians and the Babylonians, many of which have come to our knowledge." On 

 the probable use of astronomical tables by the Chaldeans, see Chasles, in the 

 Comptes rendus de 1'Academie des Sciences, T. xxiii. 1846, p. 852854.
