1568 The Theory of Force
A. MS., n.p., n.d., 3 pp. and 4 pp. (two drafts).
The controversy over innate ideas. Is there a single elementary idea for which the mind has no special aptitude? Can we frame a clear notion of such an idea? Principle of natural selection "accounts for the possession by nearly every species of animal of instinctive and concrete notions of mechanical force." Descriptions of two experiments involving use of a flywheel.

1569. [On Political Economy]
A. MS., n.p., September 21, 1874, 8 pp.
The facts of political economy fall within three categories involving the relations of price, demand, and cost of production. The first axiom of political economy: "the desire of a person for anything has a quantity of one dimension, and a person having a choice will take that alternative which will give him the greatest satisfaction." The desirability of a thing depends on other things related to it either as alternatives or as coefficients. CSP embarks on a logical treatment of political economy based on a set of propositions which are assumed. The list of propositions is incomplete and what follows by way of discussion is fragmentary.

1570. [Lecture in Elocution]

art of the first of a projected series of six lectures for ministers concerned with technique and application in the art of delivery.

1573. [Miscellaneous Fragments]
A. MS., n.p., n.d., 245 pp.
The topics range from coast survey material to texts for sermons. Notes on a sixteenth century author and notes for other historical studies; bibliographical lists; dictionary materials; ethics of terminology, especially scientific terms; philosophical terminology; philosophical schools ("How many philosophers have there been"); worksheets on existential graphs; types of argument; reflections on the logic of science; mathematical notes on secundals and on a problem in percentages; metric geometry; battery formulae; "List of Books most needed."

1574. [Miscellaneous Fragments]
A. MS., n.p, n.d., over 1,000 pp.
These fragments and scraps have been partially ordered and placed in separate folders labelled as follows: "Lexicography" (notes for Century and other dictionaries); "Skew Mercator"; "History of Science"; "Charts and Graphs"; "Materials for Mathematics Books"; "Practical Fractions and Finite Difference"; "Study of the Census of 1880"; "Biographical" (Arisbe); "Mathematical Calculations"; "Logic Scraps."

* 1575. [Miscellaneous Pages from Notebooks]
A. MS., n.p., December 26, 1913 and n.d., 41 pp.
These pages were collected for the purpose of fitting them into existent note-books. The hope persists that at least some of these pages will eventually be placed in the notebooks from which they were removed. Only 2 pp. are dated: These pages are "on what it means to say that a line is continuous." Other topics are the following: secundal and decimal system; probability; collection; existential graphs; telegraphic code; bibliographical notes; several pages which begin "I propose to devote this book to a record of Little Ideas."

MISCELLANEOUS NOTEBOOKS

These notebooks appeared after the initial microfilming of the Peirce collection had taken place. In order to accomplish the task of microfilming as much of the collection as possible with the least possible disruption, it was decided to place the notebooks here, trusting that the Index will bring together what properly belongs together. Following the notebooks, beginning with MS. 1596, are several items, some of them, perhaps, not strictly part of the "Peirce Collection," but which, nevertheless, have been given manuscript numbers for the dual purpose of calling attention to them and, at the same time, facilitating the work of the librarian who may, from time to time, be requested to make these items available.
