[Jour. Frank. Inst.,
A t the close of the debate, the following resolution was unanimously adopted : Resolved, That the thanks of the meeting be given to Col. LUDLOW for his interesting and valuable remarks, and that the FRA~*KLIN INSTITUTE is in full s y m p a t h y with h im in his efforts to improve the quality of the W a ter Supply of the City of Philadelphia. The Secretary's report embraced an account of progress made ill the work of preparing for the forthcoming "NOVELTIES" E x h i b i t i o n of the Institute ; a technical description of the principle and operation of the Phelps System of Telegraphing to and from Railway Trains in motion and some descriptive remarks (illustrated by photographic views from E. L. WILSON~S Collection) upon the N e w Orleans E x h i b i ti o n . T h e Secretary stated that the Institute had been invited by the Society for the E n c o u r a g e m e n t of the Arts, Manufactures and Commerce, of London, England, to nominate a suitable person, or persons, to receive the award of the " ALnERT MEDAl. '~ of the Society, w hi ch is awarded annually for " d i s t i n g u i s h e d m e r i t for promoting arts, manufactures or commerce." The Secretary added that the Committee to w h i ch this agreeable duty had been confided would be pleased to receive suggestions from members of the Institute. Adjourned. ~VII~LIA~I H.
