succeeded by Dr. Isaac Hays 19 whose early services to the society, 

 especially as Curator and Chairman of the Publication Com- 

 mittee, established the propriety of his election, for there is no 

 doubt that to his zeal and ability alone was due the continuation 

 of the first series of the Journal. He presided with dignity and 

 efficiency for four years, and was then succeeded by Dr. William S. 

 W. Euschenberger. 



Notwithstanding the space provided by the additional story 

 completed in 1855, the need of more room for the arrangement of 

 the collections was again becoming urgent. A committee of 

 forty was appointed in December, 1865, to solicit subscriptions for 

 the erection of a fire-proof building on a lot of ground not less 

 than three times the size of the one then occupied and as close 

 to it as possible. In January, 1867, a Board of Trustees of the 

 Building Fund was elected by the subscribers, Dr. Euschenberger 

 being made Chairman, George W. Tryon, Jr., Secretary, and 

 William S. Vaux, Treasurer. Without the least forgetfulness of 

 the loyal service and the courageous perseverance in the face of 

 many discouragements of the other members of the Board, it may 

 be claimed with justice that to these three men was due the suc- 

 cess of the undertaking. 



After an ineffectual attempt to secure possession of one of 

 the four Penn Squares at the intersection of Broad and Market 

 Streets, and the rejection of propositions to move to Fairmount 

 Park and elsewhere equally undesirable, a lot of ground of 

 adequate size on the southwest corner of Nineteenth and Eace 

 Streets, was purchased in 1868 for $65,298. A plan submitted by 

 James H. Windrim, in competition with Messrs. Frazer, Furness 

 and Hewit, and John C. Trautwine, was adopted, and Mr. Wind- 

 rim was appointed architect. It was not, however, until May, 

 1872, that the Building Committee was authorized to commence 

 the edifice. The cornerstone was laid at noon on Wednesday, 

 October 30, addresses being delivered by Dr. Euschenberger, Eev. 

 Elias E. Beadle, Dr. J. Aitken Meigs, Dr. Horatio C. Wood and 

 Eev. George Dana Boardman. 



So untiring had Dr. Euschenberger been in the fulfillment 

 of the trust confided to him as Chairman of the Board of Trustees
