Charge of having them fent hither to DuhltHy that I 
might have a compkat Set and Sample of all the various 
Golums the Giants Caufway affords; I fay, obferving of 
thefe, I find fome of the Joints actually want this Cavi- 
ty and Rifiiigy as thofe of Four and Six Sides I have now 
in my Houfe, and are only united to one another by 
Superficies touching clofe in Planes that run a little flant- 
ing and not parallel to i'wt Horizon. Yet this may 
be only a chance Formation, fince the univerfal Jointing 
of th^'whoh Caufway, is certainly otherwise ; but I muft 
take notice, that the Ho/lows and Convexities are not 
conftantly formed and moulded in the Stone with all that 
Accuracy and circular exadinefs the Artifl: has pleafed to 
exprefs them in the Figures. 
Theft Cavities in fuch Joints as are uppermofl, and 
lye expofed to the open Air on the Surface of the Cauf 
way, afford no fmall Ufe and Advantage to the poorer 
fort of. the People in the Neighbouring Country, with 
whom it is a common Practice in the Summer time, 
when they want Salt, to fill thefe natural Bafons with 
Sea Water, which by reafon of their Shallownefs are of 
fo commodious a Shape, that in the Space of Four Tic/es 
they find all the Water that was left in them exhaled, 
and the Salt remaining dry in the bottom of the Hol- 
lows. Yet whether fome intrinfick Principle in the Na- 
ture and Body of the Stone may not contribute a great 
deal, as well as the outward Figure of its Cavity, to 
fuch a fudden Evaporation of the Water, and Chriftali- 
fatioa of the Marine Salt, in fo Cold and Northern a Cli- 
mate as this is, I leave to be further GonMiJered. 
But, there is another Irregui%rity.,:l muft t;ake Notice 
of, which is, that One of the Joints of the C^j^/m'^?/ a 
Pentagon fent me hither to Town, is Ca^ ojs, both at 
'i;:op and Bottom : . and I am toidj .?imong t^ie -ptkr Fir
