Appendix. 
Of fome Particulars lately given by Dr. Chritlopher 
Merret. 
T O which I fhall only premife a Note concerning 
the CLYSTER-BAG, defcribed p. 23 c?. of this 
Catalogue ; but fhould have been placed in the laft 
Part. ’Twas given by Sir Rob. Southwell 5 of whom I lately 
learn, That the Portugal Negros, having rowled a lump of 
Clay into the fhape mention’d p. 2 3^. 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 5 which being dry’d in the Sun, 
will be almoft 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.
