together, the spirit of wine will insinuate, and ascend seemingly in an intirei 

 body, between all their contiguous parts. And 1 have since observed, in plung- 

 ing the planes in spirit of wine, oil of turpentine, and common oil, that all 

 these different fluids arose between them, as the tinged water ; only with this 

 difference, that the common oil rose very sluggishly, being near an hour in 

 rising so high between them, as the other liquids would in less than half a 

 minute. They all rose in an intire body, from side to side of the planes, with- 

 out those intervals or spaces, which generally happen on the ascent of the 

 water. I likewise took a couple of round glass planes, and having laid them on 

 each other, without paper, or any thing else between to keep them separate ; 

 in this manner I plunged one edge just under the surface of the tinged 

 liquor, and found the water almost instantly had reached the extremities of 

 them in all parts : by which we find, that the water not only ascends directly 

 upwards, but runs sideways, obliquely, or in any direction. 



//w Experiment on the different Densities of common Water, from the greatest 

 Degree of Heat in our Climate, to the Freezing Point, observed by a Ther- 

 mometer. By Mr. Fr. Hauksbee, F, R. S. N° SIQ, p. 267. 



I caused a quart of water to be heated near scalding hot, and then put it 

 into a convenient glass with my thermometer, the spirit in which soon rose to 

 the ball at top, where it remained, till the water cooling caused it to descend: 

 by this time the spirit in the thermometer and the water were become of an 

 equal temperature; and when it had descended to 1 30 degrees above the freez 

 ing point, I began my observations, as below. I weighed a small bottle in 

 it, and found the bulk of water equal to it in that state was 574 grains; when 

 the spirits had descended to 80 degrees above the freezing point, the bulk of 

 water equal to the bottle then weighed 3 quarters of a grain more than before; 

 at 30 degrees above the freezing point, the quantity of water equal to the bulk 

 of the bottle was again increased about 3 quarters of a grain ; and at the freez- 

 ing point, it weighed still something more ; in all about two grains from J 30 

 degrees above the freezing point, to that very point. Which seems consider- 

 able, and ought to be noticed by gentlemen who judge of a mineral or any 

 other water by its weight, when they have not an opportunity of making the 

 experiment at the fountain head ; for there I suppose the water is at the same 

 degree of temperature at all seasons. 



Now according to this experiment, I find that water is condensable by cold 

 one 28th part of the whole, from the greatest degree of heat in this climatie. 

 Supposing then, that the water in the sea should suffer the same alterations by
