Of fome articular s lately given by Dr. Chriftopher 
Merret. 
TO which I fhall only premife a Note concerning 
the CLYSTER- BAG, defcribcd p. 23?. of this 
Catalogue 3 but fhould have been placed in the laft 
Part. Twas given by Sir Rob. Southwell 3 of whom I lately 
learn, That the Portugal Negros, having rowled a lump of 
Clay into the fhape mention d ^.239. they cut the Branches 
of a certain Tree which yields an Oily Gum, and fo turn the 
Clay round, as the Gum drops upon it, till it hath cover d it 
all over like a thick Skin 3 which being dry 'd in the Sun, 
Will be almoit as tough as Leather. Then picking out 
the Clay, it ferves them for a Bladder. To which they 
tie the Shank of a Hare for a Pipe : and fo filling it with 
Sea- water, as often as they feel themfelves much chafed 
with heat, put it up for a Glyfter. Thefe Bags they com- 
monly hang by their fides, to be always ready for their 
ufe. 
The Particulars given by the Doctor are thefe that fol-
