Now according to this Experiment, I find, that Wa- 
ter is condenfable by Cold one 28th part of the Whole, 
frorh the greatefi: Degree of Heat in this Climate. Sup- 
pofing then, that the Water in the Sea fhould fufier the 
lame Alterations by the change of the difierent Seafons, 
(*as I fee no reafon but very nearly it muft^ it would be 
eafy to compute, that a Ship which fliould draw two Fa- 
'tlioms, or 12 Feet Water, in fuch Weather.as is under- 
vllood by the greatefi: Degree of Heat, would draw about 
half an Inch lefs from the greater Denfity of the Fluid, 
when reduc’d to the premention’d Degree of Cold ; and 
'Confequently woul Sail better at that time. 
Bat this is not all that occafion’d the making this Ex- 
'periment, for I did it in order to another. And fince I 
find that Water is capable of Dilation and ContradHon 
' by Heat and Cold, I fee no reafon why the fame may 
-not be performed by force, notwithftanding the many 
' /attempts to determine it have as yet been fruitlefs. For 
- lince the conlfituent Parts of the Fluid, are capable of 
.being remov’d at greater Di'ftances one from the other 
by Heat, and become more clofely united by Cold ; fo I 
conclude, that there mufi: be fomeBody contained in’t 
• -of an ElaftickQuality, which f I think J mufi: be fubjedf 
-to the fame Laws of fuch a Body; that is, be capable 
of Compreffion by force, as well as to become more 
Denfe by Cold. But the Ilfueof this, I mufi: leave to 
more proper Seafon.
