✦ Synopsis

Mr. Herschel has rendered an acceptable service by collecting the labors of engineers on this subject, performed at different times, and presenting them in one view. The following remarks are suggested by his recent articles in the JOURN.CL. ~ M. Dupuit's theory, quoted by Mr. H., calls for a word of comment. The proposition, "Flowing water can hold bodies in suspension which are much more dense than it," is undisputed and indisputable. It may be also true that " the lower planes of the stream can carry more voluminous solids, or more of them, than those higher up," though not for the reason contemplated by M. Dupuit. As to the statement, however, which embodies the substance of his theory, viz., " The power of suspension depends upon the relative velocity of the filaments, and is greater the greater this relative velocity is," I hold that a more fanciful proposition was never reduced to writing. It may be observed, that this theory is more fully stated in the Humphrey's Abbott Report, p. 139, thus: " Dupuit demonstrates (Chapter ¥, "Etudes Thdoriques et Pra-Fla. 1.
