Twenty teirs since, Mr. Charles Green, .

undertaken, that a continual current set

in this country Prof. Wise discovered the
exntence Of the current ia the course Of his
early hAllooping experiments. Nv own ex.

sideTable altitude, verified this theory. Later
intsss.ss6oo', towever, have proved that this
