Mr.S.has incorporated it into the specification for the patent.

Please, therefore, not to proceed with the type or portrule as now constructed: I will see you on my return and explain it in season for you to get one ready for us.
"I find it a most arduous and tedious process to adjust the specification.

I have been engaged steadily for three days with Mr.S., and have not yet got half through, but there is one consolation, when done it will be well done.

The drawings, I find on enquiry, would cost you from forty to fifty dollars if procured from the draughtsman about the Patent Office.

I have, therefore, determined to do them myself and save you that sum." The portrule, referred to above, was a device for sending automatically messages which were recorded permanently on the tape at the other end of the line.
