Dr. Abbot has spent more than twenty years' research work on this subject and is perhaps the best living authority thereon.

The lecture was illustrated by means of slides showing the apparatus used and the methods of calculation employed in measuring the amount of heat received by the earth from the sun. This lecture presented an interesting subject in a manner that was very entertaining and instructive to the members of the corps.

COMMENT.

During the calendar year 1924 the Office gained 11,243 mechanical cases.

The gains in dates have been notable. One year ago there were 42 divisions over 7 months behind, now there are only 5; one year ago there were 20 divisions over 8 months, now there are none; one year ago there were only 2 divisions under 5 months, now there are 15.

One year ago the design division was about 2 months behind, now it is only one month. The trade mark division was about 2 months behind on new work and one month on old, now it is 1 month on new and 15 days on old.

ETHICS.

The question of a code of ethics was taken up several years ago by the Cleveland Patent Law Association. A committee of which Mr. Geo. W. Saywell was chairman prepared a code which was adopted in part by the Association. However so far as the editor is aware, the first complete code to be made effective is the one adopted by the Chicago Patent Law Association on the occasion of its fortieth anniversary. The full text of this code, together with the report of the commitee which prepared it, appears elsewhere in this issue.
