Manchester, 7 January 1858 

Dear Moor, 

Herewith the beginning of C.?” I shall try and do a few more 
articles tomorrow evening. It seems to me that there are only 2 
articles for which material will be difficult to obtain—perhaps 
impossible in sufficient quantity—namely, cars (Percussion) and 
‘Camp’ (Roman, Hebrew, Greek). The excerpts I made from Riistow 
about Caesar’s camp* amount to very little for, though I had 
ordered my own copy of Ristow, the bookseller supplied an 
altogether different book. In the case of Percussion cars, what I 
chiefly need is the story of the discovery of potassium tetrachlorate 
and its explosive qualities, likewise the dates when percussion 
fire-arms were introduced into the various armies. These two 
things would be useful to have. If you could manage to go to the 
British Museum and rout out something on this for me I could 
soon have these articles ready also, otherwise they'll hang fire since 
the libraries I use up here have no information on the subject. 

If, by the way, Monsieur Dana can’t be bothered to reply when 
we send him our lists, he has only himself to blame. He could have 
sent a list for D long ago. Now I shall make one out myself. At all 
events the chap seems to be taking the whole business very lightly; 
I only hope he’s sent you some money for it, otherwise it’s high 
time to start kicking up a fuss. 

Charley” is in Holland and will be going to Switzerland. Luckily 
the shortage of orders makes it possible for me to leave most of 
the tasks connected with the year’s end to the office boys, so that 
Ym not unduly burdened with work. Tuarss one coop Jor. 

I enclose today’s Guardian from which you will see that there is 
still a lot of short Time here. Next week it may ease again somewhat. 
At present I am sending you only those Guardians in which there’s 
something of commercial interest. 

I am reading, inter alia, Clausewitz’s Vom Kriege. An odd way of 
philosophising, but per se very good. On the question as to 
whether one should speak of the art or the science of war, he says 
that, more than anything else, war resembles commerce. Combat is

to war what cash payment is to commerce; however seldom it need 
happen in reality, everything is directed towards it and ultimately 
it is bound to occur and proves decisive.’ 

Many regards to your wife and little ones.
