The importance of thisconsideration will be evident, from the fact that in the case here given, no less thanthirty-seven per cent, of the length of tlie sheet was cut away ; and while the castingsthat were riveted around the openings were supposed to possess sufficient rigidity tomake up for this loss of section in the plate, yet the strains resulting from such a dis-position of the openings are not easily calculated, and it is evident that the failure ofone or two rivets, either from imperfect workmanship or from undue stress, would alterthe character of these strains materially, and might lead to serious results. The boilerfrom which this example was taken exploded with disastrous effect, killing over twentypersons, and causing an enormous property loss ; and while we do not say that theexplosion was primarily caused by th
