It would be interesting to show your printing machines in operation, and we shall endeavour to do so if arrangements can be made. It would expediate matters if you could call here to see our space. To-morrow between 11 a.m. and 1p.m. or early next ^week^ between 11 a.m. and 6 p.m. would suit us very well if convenient to yourself.
Asst. Sec. R.S. [Assistant Secretary, Royal Society]'.
