chronological calendars is perhaps the strongest point. Not only are series of names like our signs of the zodiac used to record periods of time, but such series are combined together, or with numbers, in both countries, in a complex, perverse, and practically purposeless manner, which, whatever its origin, can hardly by any stretch of probability be supposed to have come up independently in the minds of two different peoples. The theory of the successive destructions and renovations of the world, at the end of long cycles of years, was pointed out by Humboldt as another bond of connexion between Mexico and the Old World. If these agreements between North America and Asia are to be read as indications of a deep-rooted connexion, this ought to have left many other traces. Of customs, the occurrence of which in America as well as in the Old World would be well explained by such a view, something has already been said.

In the midst of the milky sea, Vishnu him-
