it to beare as good Weight, as the Bodies did feuerally : Not with handing 
a good deale of Wafte, by a thicke Vapour, that iffueth during the wor¬ 
king : Which fheweth that the opening of a Body, doth increafe the 
weight . This was tried once, or twice, but I know not, whether there 
were any Errour, in the Trtall.

Body when it was put into the Bath, could not get downe fo eafily, as in

than the weight of the Aqua-Fortis.
