Kor hath this Laudanum Simplex (by his obfervationj only this 
effedt in the Indies, where he faith, heufed it in all cafes to all 
ages, even fucking Children, but that even here in England he 
gave it not long ago to a Lady in the Colique bilious, never weigh-

Seventhly, he takes notice, that the Obfervation, which Ovi- 
fiflWhath about Lice y which is, that they leave the Spaniards as 
they go to the Indies in fuch a degree, and meet them again in 
the fame Latitude in their return, is very true. For though the 
flirips, they went in, with fuch a multitude of Servants and Sea- 
men, were not over-cleanly, yet ( as he remembers) before they 
came to rhe Tropick, there were none Lowfie* whereas before, 
one could not walk amongft them, but his cloaths would gather
