          offense - In reference to your battery I thought 
the troughs on the [?] you propose will
be excellent. I know not if you intend
to introduce the [crossed out: illegible] principle of movable
connections. I would not advise this
for the whole [series?] [crossed out: illegible] as when there
are many plates it will be inconvenient
but I would divide the battery into sections
say of 10 plates each and arrange them
so with movable connections as to produce
intensely a [quantity?] - Give me a further
detail of your plan
