Now if the Chain be placed near the Axletree, tliemotioti 
will be the nicer and larger ; if farther ofF^then it wilt be lefs : 
For Example, the motion of 2 more than that of 3, and 3 than 
that of 4, &c. as you may perceive by the figures 2, 5, 4,5 
which are placed in this figure by the lower end of the hand near 
below the Axekree thereof. 
From this contrivance it, was, that I have for this five or fix 
years paft made thefe following Obfervations. 
I. That thefe Pannels of Deal-wood will move by flirinking 
nioft in Summer, and fwelling moft in Winter-feafons ; but will 
vary from this^ according to the change to the then more or lefs 
heatorcold^moifture or drought that the teiKper or feafonof 
the year, fuch as Spring and Fall, do produce ; it being then 
moreapt tofvvell orflirink on the fudden, but not attaining 
then to the higheft fljnnking or fwelling,as in Stumer and Win- 
ter it'doth. 
2 . HiaC for the moft pare, efpecially in the Spring and Sum- 
mer-time, this Motion happens only in the day time; for then 
generally all night it refts, and moves very feldom. 
3* That one kind or manner of this Motion happens in dry 
fair weacher^but fometimes in the fore- part of the forenoon ,and _ 
fometimes not until the latter part of the forenoon^ and then at 
that time it relaxes or fwells the Deal for about two or three 
hours^ more, feldom; Iefs,often ^ and then all the afternoon 
after llirinks ; nay, fometimes even when a fmall Rain hath 
newly fallcn.or is then falling ; and this not fo often, but more 
feldom in Winter, or cold moift weather. 
4. This ft.rinking is gradual very ofcen,orfor the moft part 
a little after a moift time (1//«,) the firft day after moifture it 
fbrinks a little, the fecond day more,and fo yet more according 
to thetheaiimeof year, and as it is then inclined to moifture 
or drought,and alteration of the wind and the then heat or cold. 
5»The winds being in the North,North-Eaft,andEaft,winter 
and fummer/or the moft part at that time cheDeal ftrinks in the 
night alfoas well as in the day; bur not fo much : which is a figji 
of drying weather ,and fometimes of froft or cold inWinter;hear 
§r fcocching in Summer^ in a clear day.But on the contrary, the
