It appears then that the ancient Aryan scheme, though _possibly_ supplying us with the origin of one of the widest spread of our words, is not universally allowed to do so. This origin, however, appears to derive support from the apparent occurrence of the original of another well-known ancient classical word in the same scheme, that is Varuna, obviously the same word as [Greek: Ouranos], and Uranus, signifying the heavens. Less clearly too perhaps we may trace other such words to the same source. Thus the Sun, which according to these primitive conceptions is the husband of the Earth, which it nourishes and makes fruitful, was called _Savitr_ and _Surya_, from which the passage to the Gothic _Sauil_ is within the limits of known etymological changes, and so comes the Lithuanian _Saull_, the Cymric _Haul_, the Greek _Heilos_, the Latin _Sol_, and the English _Solar_. So from their _Nakt_, the destructive, we get _Nux_, _Nacht_, _Night_. From _Glu_, the Shining, whence the participle _Glucina_, and so to _Lucina_, _Luena_, _Luna_, _Lune_. Turning from the ancient Aryans, whose astronomy we know only from poems and fables, and so learn but little of their actual advance in the science of observation, we come to the Babylonians, concerning whose astronomical acquirements we have lately been put in possession of valuable evidence by the tablets obtained by Mr. Smith from Kouyunjik, an account the contents of which has been given by Mr. Sayce (_Nature_, vol. xii. p. 489). As the knowledge thus obtained is more certain, being derived from their actual records, than any that we previously possessed, it will be well to give as full an account of it as we are able.
