Chapman, , [Read May 9, 1918.] In a paper W published in The Physical Review for March,1917, Mr. R. W. Burgess has demonstrated that the ordinarymethod of solution, for the problem of determining the deflec-tion of a column under load, leads to results that are veryconsiderably in error when applied to the case of a long, thincolumn, pin-jointed at the ends, and subjected to compressionalong its axis. In all such problems the solution is obtainedby the integration of a certain differential equation. Theexact solution is, as a rule, somewhat difficult; but a verysimple solution can generally be obtained by neglecting the dy * term involving the square of —, and as this is supposed to d x give results that are quite sufficiently accu
