Dear Sir:

We send to your address per Registered Post this day, a 1-6 inch
objective to be exchanged for the 1-4 inch sent you with Microscope
on May 31st, as per our letter of that date. Please return the 1-4
inch on receipt of this 1-6 inch in the same manner.

We have not yet received the eye-piece micrometer, which you or-
dered at the same time, but will send it soon as possible.

Yours truly,
