tent the same purposes as this society. That is, the advancement of electrical science.

Mr. Beach's recollection of the company is that it was intended to secure electrical inventions as fast as they made their appearance, in fact to build up a large organization on the plan of some of our modern companies. Mr. Beach published in the Scientific American of April 20th, 1867, an article entitled "Electric Light; Wilde's Magneto Electric Machine "

[From the Scientific American, April 20th, 1867, p. 248.]

ELECTRIC LIGHT-WILDE'S MAGNETO ELECTRIC

MACHINE.

The subject of electric light is now attracting more attention than at any former period. Every day we find something about it in our foreign and domestic exchanges. Three of the city newspapers within a few weeks have printed full column editorials under the title of Electric Light. The lighthouse directors of England, France and America, simultaneously but independently, are instituting experiments on a liberal scale to determine if the electric light may not be the best for lighthouses. And as a natural consequence of these movements, a business association under the style "The American Electric Light Co.," has been chartered and will be soon in active operation. This new interest in electric light was originated by the exhibition in England of the machine which is described in this article. No wonder, for the light from it is the most powerful artificial light ever produced. Mr. Crookes testifies that when he saw it, it had three or four times the power of the sun light. The machines first built were found too powerful for lighthouse illumination, and it was found advisable to make machines for that purpose of only one-half the original sizes.

Professor Seeley had never seen a self-exciting dynamo, but had kept well abreast of the European work on the subject so far as possible by reading, and was also familiar with the arc of Davy and the incandescent carbon of Starr. The machine built by him is before you, and you can see that the design is not bad, considering the date of manufacture. It passed through a fire in Professor Seeley's office at 26 Pine Street, early in December, 1874, and was rewound with the same field wire with new insulation, and new armature wire as nearly like the original as possible.

Mr. Wm. H. Burnap, of 259 West Twenty-seventh Street, who made the repairs, confirms Professor [Seeley's recollection as to these points. Professor Moses G. Farmer saw the machine when

it was comparatively new, but the exact date I have not been able to ascertain. Professor Farmer estimated the capacity of the machine as about two or three telegraph cells, meaning Grove cells. This estimate is evidently too low if the machine be run at a reasonable speed, but the machine was originally turned by hand power, and the estimate was probably about right. The necessity of a high speed to secure a reasonable output was not so well understood when the machine was built as it is now. Mr. Weston saw the machine in the summer of 1872.

Dr. Vander Weyde remembers the machine well, and is quite certain that it was built before the company was organized, which confirmed what has already been said, but cannot fix the date any more accurately. Dr. Vander Weyde also says that he remembers when the machine was first started, that there was some difficulty in getting it to excite, owing to the field not being connected in the proper relation to the direction of armature winding and rotation. That is, the machine instead of exciting itself, demagnetized itself until the connections were reversed. This was quite a common error a long time after.

THE PRESIDENT:-I take great pleasure on behalf of the Institute in accepting from Mrs. Seeley this very interesting machine, a forerunner of a large part of the electrical development of this country. I think it proper that a committee should draw up a resolution to be transmitted to Mrs. Seeley thanking her for her kindness in making this donation. I appoint for this purpose Mr. Martin, Chairman, and Mr. Kennelly and Mr. Birdsall as members. The sentiment of this meeting will be unanimous in favor of this action, so that it is unnecessary to put the motion.

THE CHAIRMAN [W. J. Hammer]:-The Chair wishes to announce that at the meeting of the Council this afternoon the certificate of membership which, doubtless, you have all seen in the adjoining room, was adopted with one or two slight changes.

This certificate will be issued to full members only. It will be a compliment from the Institute to those who have attained a high rank professionally, and whose work in their profession and for the Institute entitles them to receive it. These certificates will probably be ready within two or three weeks and will be printed upon heavy parchment paper at about cost, namely, one dollar. The Secretary has been instructed to send out a notice, stating the conditions under which this certificate is given and other matters pertaining thereto, as soon as they are ready for distribution. The American Institute of Electrical Engineers desires to raise its status as a scientific organization in every way possible, and it is believed that by issuing this certificate to full members only, the honor conferred will be more highly appreciated and it will result in a desire upon the part of many of our associate members to apply for and to secure full membership in the Institute. While in some of the engineering societies the majority of the members are active or full members, and there are comparatively few associate members, in the Institute of Electrical Engineers the opposite is the case, and the issuing of this certificate under the conditions as recommended by the Special Committee will prove advantageous to the interests of the Institute as well as to the members receiving the same.

I will refer to the subject of badges as several members have asked me about them to-night. Some of the badges were delivered to-day, and I might say that within the next week or ten days the first fifty will be ready. Five or six moulds have been made and a great deal of trouble has been taken to make them

correct. Those who apply to the Secretary first will naturally receive the badges first. The price is $3.00.

There is one other point to which I would like to call the attention of the Institute before taking up the paper. On behalf of the Ways and Means Committee of the Institute in charge of the World's Fair matters I would like to state, as you have already heard, that headquarters have been secured at the Columbian Exposition. The authorities there have given us two excellent rooms adjoining the official headquarters in the Electricity Building. They have promised to give us excellent facilities therelong-distance telephone service, electric light, telegraph service, fire protection and police patrol. The Council has instructed its Secretary to go there' and represent the Institute during the meeting of the International Electrical Congress and largely during the season. We have extended invitations to our foreign electrical friends to make use of our headquarters, to have their mail addressed there, to write their letters there and to see their friends there, and it is very desirable that we should make those headquarters interesting, and with that end in view, the Committee is endeavoring to secure a large number of exhibits of great historical interest. We want letters, books, small models and things of that character, autographs, photographs, etc., which

will be of interest to our friends and to our members. We would like to make our headquarters the most attractive spot in the Electrical Building. You have doubtless noticed in the other room small reproductions of photographs of a great many eminent men. Those are largely based on a number of photographs that I have been collecting for many years, and there will probably be four or five of those large frames of photographs sent out there. The Committee has been promised some of the things that belonged to Professor Morse and to Franklin, and has already received some of them. The Secretary placed in the Committee's hands to-day the original list of the members who signed the call for the organization of the American Institute of Electrical Engineers. That will be placed in the exhibition. These and many other things which we shall have, will make the Institute headquarters very interesting to all our members and our visiting friends. I might state that one of the large publishers, Van Nostrand, has promised me to place in a few days a complete electrical library at the headquarters, and that this library, under the care of the Secretary will be at the disposal of our members. It will be a very complete and doubtless interesting exhibit. I trust that members who have interesting things will send them to the Secretary or to myself as Chairman of the Committee, and if they know of some particular feature which would be of interest and value that they would kindly communicate with the Secretary or the Committee.

We will now have the pleasure of listening to Mr. A. E. Kennelly's paper upon "Impedance."
