The story of Marx abandoning further work on _Capital_ after reading Jevons 
and Menger is totally improbable.  The only criticism which he worried about 
was that raised later by Boehm-Bawerk (Karl Marx and the Close of his 
System) and which Marx anticipated in vol. III (part II, ch. IX) of _Das 
Kapital_.  Marxists scholars dismissed the Jevons Menger theory en passant 
(e.g., Antonio Labriola, in the Postscript to the French edition of 
_Socialism and Philosophy_ in 1898 and R. Luxemburg in the chapter "economic 
development and socialism" of _Reform or Revolution_ discussing the 
"Boehm-Jevons" (sic) reference of E. Bernstein.   To my knowledge, the first 
complete discussion of the marginalist school by a marxist economist was 
that of Nikolai Bukharin, "The political economy of the rentier" written in 
1914 and translated into English as _The Economic Theory of the Leisure 
Class_ in 1927.     

BTW, Bernard Shaw's fascination with Jevons [as Engel's 
Preface to vol. III cited by Michael Perelman points out] was the result of 
P.H. Wicksteed review of _Capital_ in Today (1884).
