conceived in the course of development was first clearly enunciated. Here the only consideration is that the economic conception in question must be of some significance to the history of science, that it is the more or less adequate theoretical expression of the economic situation of its time. But whether this conception still possesses any absolute or relative validity from the standpoint of the author or whether it already has become wholly past history is quite immaterial. Hence these quotations are only a running commentary to the text, a commentary borrowed from the history of economic science, and establish the dates and originators of certain of the more important advances in economic theory And that was a very necessary thing in a science whose historians have so far distinguished themselves only by tendentious ignorance characteristic of careerists. It will now be understandable why Marx, in consonance with the Afterword to the second edition, only in very exceptional eases had occasion to quote German economists.

There is hope that the second volume will appear in the course of 1884.
