MARX TO NIKOLAI DANIELSON °% 

[London,] 9 November 1871 

Dear Friend, 

Enclosed are a few changes, some of them just printing errors. 
Of some importance, however, are the changes on p. 192 [p. 225], 
p- 201 [p. 234], p. 288, Note 205a [p. 309, Note 1], and p. 376 
[p. 390}, which affect the content.*” 

It would be pointless to wait for the revision of Chapter 
since for months now my time has been so taken up that I have 
not been able to get to my theoretical work (and the foreseeable 
future holds out small prospect of an improvement in_ this 
respect). 

* Certainly, I shall one fine morning put a stop to all this but 
there are circumstances where you are in duty bound to occupy 
yourselves with things much less attractive than theoretical study 
and research. 

My warmest thanks for all the kindness I have met with on your 
part. The writings of Ehrlieb* I am partly acquainted with. I 
compare him as a writer to Lessing and Diderot. 

I have received some curious numbers of the Moscow Gazette. 

1,718 

Yours truly,*

[Appendix] 

p. 68, Note 52, line —2 [p. 109, Note 1, line —4] read ‘ne pouvant’ 
instead of ‘ne pouvant pas’. 

p. 83, Note 62, line —6 [p. 123, Note 1, line —23] read ‘specie’ 
instead of ‘species’. 

p. 192, line 3 [p. 224, line —2] read ‘The annual return’ [Umsatz] 
instead of ‘The annual income’ [Einkommen]. 

Ibid., line 7 [p. 225, lines 2-3] read ‘Of the 3/osrds’ instead 
of ‘Of these 7%/s5 working hours’, so that the sentence should 
now run, ‘Of the 7%/ssrds (constituting the whole £115,000)’, 
etc? 

Ibid. Insert the following after Note 32, p. 192 [p. 225, Note 1): 

Author’s addition to Note 32: ‘Apart from errors in principle, 
Senior’s statement is confused. What he wants to say is this: 

‘The manufacturer employs the workman for 11'/: hours or for 
23 half-hours daily. As the working day, so, too, the working year, 
may be conceived to consist of 11 '/2 hours or 23 half-hours, but each 
multiplied by the number of working days in the year. On this 
supposition, 

the 23 half-hours yield a total product of £115,000; 

1 half-hour yields 1/s3x £115,000; 

23 half-hours yield *°/.3x£115,000=£115,000°; 

20 half-hours yield 7°/.3x£115,000= 100,000, i.e. they replace no 
more than the capital of £100,000 advanced. 

There remain 3 half-hours, which yield */o3x£115,000=£15,000 
or 

the gross profit. 

‘Of these 3 half-hours, one yields MosX£115,000=£5,000; ice. 
it makes up for the wear and tear of the factory and the machi- 
nery. 

‘The remaining 2 half-hours, i.e. the last hour, yield the last 2 fos of 
the product, i.e. “/23x£115,000=£10,000, i.e. they produce the net 
profit. Q.E.D. 

‘In the text, however, Senior says, 

‘“The remaining 2/ggrds, that is, the last two of the twenty-three half-hours of 
every day, produce the net profit of 10 per cent.” 

‘That is to say, he suddenly confuses the 23rds into which he

23/ogrds,..’ - > This line is omitted from the English translation. 

has divided the product with the half-hours into which he has 
divided the working day.’

- in 10 years, you pay me daily '/,9950 instead of '/s650 of its total 
value, i.e. only */3 of its daily value, and you rob me, therefore, every 
day of */; of the value of my commodity.’

and ‘teinturiers’ instead of ‘teinturieurs’. 

p. 376, line 20 [p. 390, line 1] read ‘The less value it gives up’
