We tooke a slender Pipe of a convenient length & caus'd the lower part of it to be so bent at the flame of a Lamp as to be reflected upwards & be made parallell or allmost parallell to the longer leg of the syphon, which was above half a yard [ 'high' deleted] long, the upper part of the shorter leg of the Syphon was also at the same [ 'length' deleted] Lamp drawne out into a straight but very slinder <pipe> (parallell likewise to the longer leg) which [ 'would' deleted] was not much bigger than a pigeons quill. The Syphon being thus fitted, there was about 4 inches of {mercury} power'd into the longer leg which passing through the Curvature into the shorter leg, ascended about [ 'pretty' deleted] an inch and more into the slender pipe. This done we [ 'we made f' deleted] 1. we <measur'd by>[replacing 'made'] a thread held horizontally & stretch'd from the surface of the {mercury} in the capillary Pipe to the longer leg of the Syphon, that this <small> surface was near 5/8 lower than of the {mercury} in the longer leg. And yet the length of that Mercurial Cylinder did not exceede four inches.
