Moore & E. Aveling tr. K. Marx Capital II. xxv. 625 The composition of capital is to be understood in a twofold sense. On the side of value, it is determined by the proportion in which it is divided into constant capital or value of the means of production, and variable capital or value of labour-power, the sum total of wages. On the side of material, as it functions in the process of production, all capital is divided into means of production and living labour-power... I call the former the value-composition, the latter the technical composition of capital. Between the two there is a strict correlation. To express this, I call the value-composition of capital, in so far as it is determined by its technical composition and mirrors the changes of the latter, the organic composition of capital. Wherever I refer to the composition of capital, without further qualification, its organic composition is always understood. 1937 M. Dobb Polit.

[compare French molécule organique (1749 in Buffon)] (a) (in the terminology of Buffon) any of the minute indivisible particles of which living things are constituted and by means of which they reproduce (now historical); †(b) (in the terminology of L. Spallanzani) a spermatozoon (obsolete rare); (c) a molecule of an organic compound (see sense A. 7a).Sense (b) is apparently only attested in dictionaries or glossaries.
