✦ Synopsis

Determining of the gluon polarisation in the nucleon, by measurement of the double spin asymmetry of the photon-gluon fusion process is the main goal of the COMPASS experiment at CERN. Experiment uses 160 GeV polarized muon beam and polarised 6 LiD target. Photon-gluon fusion events are selected using charmed mesons and hadron pairs at large p T . Preliminary results on charm signal extraction, and spin asymmetry A Ξ³ * d of the cross sections for high p T hadron pairs production are presented.

The following experiments were made under the direction of the writer at the New York Navy Yard during the months of March and April, 1867, to ascertain the weight of water lifted through a given height per pound weight of steam expended, by means of a reciprocating-pump, a rotarypump, and a steam s
