fernalis, and fix ounces of calcined bones to twenty 
gallons of fea-water, as he diredis. This water la- 
thered well with foap, and boiled peas well. 
29. I diftilled alfo fome fea-water with half an 
ounce of ftone-iime to a gallon, from the Clee hills 
in Herefordfhire, which having been preferved ten 
months in a firkin, had flacked to dry powder. This 
diflilled water did alfo lather well with foap, and 
boiled peas well ; which proves that the lime, which 
is a fixed body, does not dilfil over with the water. 
Since I made this diftillation. General Oglethorpe in- 
formed me, that his father. Sir Theophilus, told him, 
that lime was one of the ingredients, which he 
and the reft of the patentees, in Charles the fecond’s 
time, called the cement, with which they made 
diftilled fea-water wholfome. 
30. I diftilled alfo fome fea-water with the like 
proportion of powdered chalk, which boiled peas 
well, and was better tafled than the waters diftilled 
with lapis infernalis, or lime. I diftilled alfo fome 
fea-water with an ounce of chalk to a gallon, but 
found no difference in the tafte of this, and that 
which had but half an ounce of chalk to a gallon : 
So that half an ounce of chalk to a gallon of water 
will be fufficient j but where the fea-water is falter, 
or more bituminous, more chalk may be added if 
needful.
