sometimes for pans and basins to dress their meat in : but they take care to 

 keep them continually moving, while they are over the fire, for if the flame 

 catch them, they are soon burned. 



The Californians have a great deal of liveliness, and are naturally addicted to 

 raillery ; as we found when we began first to instruct them. We have not 

 found among them any form of government, religion, or regular worship. 

 They adore the moon, and cut their hair in her decrease, in honour of their 

 deity ; which they give to their priests, who employ it to several superstitious 

 uses. Every family makes laws as they please, which is plainly the reason that 

 they are so often at war with each other.

On the Circulation of the Blood in Fishes, ^c. Bij Mr. Leuwenhoeck,, F.R.S. 



N*' 319, p. 250. 



I viewed the hearts of several fishes, particularly that of the large silver eel, 

 the motion of which lasted near 4 hours, after it was taken out of the 

 body of the fish, which motion was very regular ; for when the blood is pro- 

 truded out of the heart, it is not carried into the great arteries with the same 

 velocity, which, in that case, would be overcharged with the great quantity of 

 blood : but the blood thus coming from the heart, is forced into a small white 

 vessel, almost of the shape of a pear, and which one would take for a kind of 

 bladder ; one orifice of which was united to the great artery, and the other to 

 the heart ; in the latter orifice is a valve, the use of which is, to prevent the 

 blood, protruding from the heart into the said vessel, from running back again 

 into it : which vessel having been cut across, I observed the inside of it to be 

 furnished with a great many small particles, so that it was in a manner filled 

 with them ; and the design of these internal particles I conceive to be, that 

 when the blood is protruded into the vessel, by dilating and contracting itself, 

 it may presently force the same into the great artery. So that the blood is 

 almost always running with an easy and constant course ; though at every pro- 

 trusion it must be in some manner quickened, yet that is so insensibly, that it 

 cannot be observed or felt. And the case is probably the same in beasts and 

 other large animals.
