Schleswig!) Nevertheless, plausible though it all seems, I can hardly 
see the Russians giving up, without more ado, all the spoils of 
1851/52,” the less so since they would not, so far as one can see, 
get anything in return. 

I have been engrossed in the arithmetic in your Francoeur, a 
section you would seem pretty well to have ignored, if the failure 
to correct the scandalous printing errors in the figures is anything 
to go by. Though individual bits are quite elegant, the practical 
aspect of arithmetic is handled in a shockingly inept and 
superficial manner, being better taught at any German school. I 
also doubt whether it is practical to discuss things such as roots, 
powers, series, logarithms, etc., even at elementary level, merely in 
terms of numerals (without any recourse to algebra and, in racr, 
without presupposing an elementary knowledge of the same). 
Although the use of numerical examples by way of illustration 
may be a good idea, I should say that to limit oneself to numerals 
is, in this case, less conducive to clarity than simple algebraic 
treatment with a+b, precisely because the general expression is 
simpler and clearer in algebraic form and is something which 
cannot be dispensed with here. Admittedly, this particular section 
is really beneath the dignity of the mathematician par excellence. 

I shall send you Danske” papers tomorrow. In several Jutland 
towns Prussian officers are said to have objected very strongly 
before carrying out the confiscation in accordance with orders. - 
Generally speaking, there have been no complaints anywhere 
about the troops, only about the generals and their orders. In the 
Dagbladet England is, if anything, more roundly abused than in 
Germany. 

No other news, save that it’s bitterly cold. Warm regards to your 
wife and the girls. I Hope Tussy is CONTENT WITH THE COTTON.
