TERMS AND PRIVILEGES OF MEMBERSHIP

The members of the Institute are divided into the following classes, viz.: Resident Members, Stockholders, Life Members, Permanent Members, Non-resident and Associate Members.

Any one interested in the purposes and objects of the Institute and expressing a willingness to further the same may become a member when proposed by a member in good standing and elected by the Board of Managers.

Terms. Resident members pay Fifteen Dollars each year. The payment of Two Hundred Dollars in any one year secures Life Membership, with exemption from annual dues.

Stock.-Second-class stockholders pay an annual tax of Twelve Dollars per share, and the holder of one share is entitled by such payment to the privileges of membership.

Privileges. Each contributing member (including non-residents) and adult holder of second-class stock is entitled to participate in the meetings of the Institute, to use the Library and Reading Room, to vote at the Annual Election for officers, to receive tickets to the lectures for himself and friend, to attend the Section meetings and to receive one copy of the JOURNAL free of charge, except associate members, who may not take part in elections.

Permanent Members.-The Board of Managers may grant to any one who shall in any one year contribute to the Institute the sum of One Thousand Dollars a permanent membership, transferable by will or otherwise.

Non-resident Members.-Newly elected members residing permanently at a distance of twenty-five miles or more from Philadelphia may be enrolled as Non-resident Members, and are required to pay an entrance fee of Five Dollars, and Five Dollars annually. Non-resident Life Membership, $75.00.

Contributing members, if eligible, under the non-resident clause, on making request therefor, may be transferred to the non-resident class by vote of the Board of Managers, and are required to pay Five Dollars annually.

MEETINGS AND LECTURES

1916-1917

October 5, 1916-" The Atmosphere and Aviation."
BY W. J. HUMPHREYS, C.E., PH.D.,

Professor of Meteorological Physics, U. S. Weather Bureau, Washington,
D. C.

The relation of atmospheric circulation to gravity, temperature contrasts, and earth rotation will be explained, and brief accounts given of trade winds, monsoon winds, cyclones, anti-cyclones, etc.

A practical method will be shown of estimating the approximate direction and velocity of the wind one may expect to find at flying levels under any condition of the weather.

Those phenomena of the atmosphere which the aviator knows as "air pockets" or holes in the air" will also be discussed.

66

"Efficient Military Air Service."

BY COLONEL GEORGE O. SQUIER, PH.D.,

Aviation Section, U. S. Army, Late Military Attache, American Embassy, London, England,

War Department, Washington, D. C.

A very brief outline of the tentative plans thus far developed for producing the necessary matériel and the training of the personnel of the Army air service.

October 12, 1916-"On the Acoustic Efficiency of Fog-Signal Machinery."

BY LOUIS VESSOT KING, M.A., (CAMB.), D.SC., F.R.S.C., Associate Professor of Physics, McGill University, Montreal, Canada. The lecture will include a brief review of methods of testing fog-signal installations which have been employed in the past. Special reference will be made to the results of extensive experiments carried out by the lecturer on a special type of siren (the Northey "diaphone") at Father Point, Quebec, September, 1913. By means of a Webster phonometer" it was found possible to measure the decrease of sound intensity with distance as far as eight miles on a calm day. The acoustic efficiency of the siren was measured under various conditions by means of a thermodynamical method specially devised for the purpose. Some of the outstanding problems in the development of "acoustic engineering" based on a system of measurement will be briefly discussed.

The lecture will be illustrated by lantern slides and by the various instruments employed in the experiments referred to.
