A short account of this analytical method has been given in the July and November numbers (1877) of the Educational Times, under the name of Symbolical Language. The chief use at present made of it is to determine the new limits of integration •when we change the order of integration or the variables in a multiple integral, and also to determine the limits of integration in questions relating to probability.
