ciirvity bends a litthe upwards again. In thebreaft and gut 
the blood is without intermiffion moved with great force, and 
efpecially in the Gut, and that with fuch ftrong beatings 
downwards, and with fuch a retrocourfeand contraftion of 
the gut, that a curious Eye cannot but admire that motion. 
In the upper part of the crooked afcending Gut, which is very 
ftreight, now and then a little blood crowds thorough, which 
returns not back (and here, I prefuoie, is a little valve :) The 
blood, that is thruft thorough here, ftands lUU , and foon re- 
ceives another nature , becoming of a watery colour ; and in 
this watery liquor there do appear fome blackiflh fandy par- 
ticles, having a confufed motion, which grovv in bignefs, and

Sir Samuel Morelands u^dertakmg fsr raijing of Water. 
WHereas the Common and received opinion through 
Englmd and all Europe hath been and is , That , if a 
given Weight will force up water 20 foot high, there muftbe 
more than twice that weight to force it up 40 foot , and more 
than thrice that weight to force it up 6q foot, and fo by a Ge- 
ometrical proportion minfimtum: And likewife, that a Bar- 
rel of a Pump, 6 inches wide, doth not require a pipe,through 
which the water muft be drawnup , above i^- inch ^ or two 
inches,at themoft, in diameter; 
Sir Samuel <^lor eland undertakes to demonftrate , i. That 
he wtU force Water 60 foot high with treble the weight that 
fhall raife it 20 foot, and fo proportionably in infinitum. 
2. That by how much wider the Barrel is, in which the Forcer 
works , than the Pipe through which the water is forced up^ 
by fo much is the Engin prefTed with unneceffary weight,
