The samples of "b4ton de sable," fifteen of which were sent us, were not taken from the same cross-section, nor even from the same part of the quay wall; they are not then justly comparable.
Nevertheless, profiting by the suggestions sent us therewith, we have presumed to place them in the same hypothetical section, classifying them from the top to the bottom of the section.
We state hereafter in a table, where the samples are classed in this order, the leading results of our analysis, in percentages of lime, magnesia and sulphuric acid. Accepting the suggestions given us by a member of the Commission on Cement, We give also the weight of magnesia to the sum of the weights of the lime and magnesia. This statement may be regarded as characteristic of the condition of the specimens.
