chine for observing the Stars by day : There is a Pole eight 
or ten foot long, ercfted perpendicular in the Center of an 
Equinodial Plain ^ on the top of this Pole is faften'd a 
Telefcope, not much above three foot long, which runs 
thro' the Roof of the Chaml>er, whofe Elevation is direft- 
ed by an Aftronomical Dial upon the Equinoftial Plain, 
with $n Index fitted to it for that purpofe, which deter- 
tuines it to the Star he has a mind to obfcrve at any time. 
He is faid to be the Inventer of two other Machines of 
great artifice and ufe : By the one he will (hew at any time 
the Station of any Planet, according to the Co^ernican Hy-

what offended his Stomach ^ but forcing the Knife too far, 
it flipt down his Gullet into his Scomach : from whence it 
was taken out by an Incifion on the Left fide, a little below 
the Short Ribs, with that fuccefs, that he lived feveral 
years after it in very good health. This happen d in the 
year 1635. The Operation was performed by Dr Daniel 
Swah^ a Phyfician and Surgeon, and the Knife is kept in a 
Velvet Bag in the J^in^ofPrf^jfiaS Library^ where I faw it.
