In taking up the analysis of any problem of motion
reduction we first consider each variable on the list sepa-
rately, to see if it is an element of our problem.
Our discussion of these variables must of necessity be
incomplete, as the subject is too large to be investigated
thoroughly by any one student. Moreover, the nature of
