With regard to ray question concerning the meaning of the 
term d' otjcT ( which certainly is not connected *ith the 
re-phrasing of p.l5o to 155 )» the answer given by Kalecki is 
perfectly satisfactory: the term d' serves to insure that the 
depreciation quotas are completely re-invested, and the incomplete 
re-investment is confined to the net saving. The only thing that remains 
to be said is that the reader can't easily guess it. I, for one, 
completely misunderstood it, thinking that the incpmplete re-investment 
was intended to apply to the gross saving, so that a compensating factor 
from outside would have been necessary to establish the stationary state 
In such a case, sinde h a leckis meaning is perfectly clear from his 
letter, there might be room for a brief editorial comment to help the 
reader. 
I don't think the passages in Lange bear any relation to the 
above question/. Also I don't think that Lange made or intended any 
critioism in these/ pages. There are, however, certyin sentences which 
are difficult to understand, especially the beginning of 142 which 
you quote. Could it be the translation? Anyhow, I am pretty sure 
Lange did not intend to convey anything "unorthodox" in these pages. 
I hope these comments may be of some help to you. 
Do not hesitate to ask if I have not made myself sufficiently clear.
