the work according to the plan. It will be published by the Conch- 

 ological Section of the Academy, of which Mr. Pilsbry is the Con- 

 servator, 



Mr. Tryon published the first volume of Structural and System- 

 atic Conchology, in 1882 ; the second, in 1883, and the third and 

 last volume, in 1884. The three volumes contain 1195 octavo pages 

 of text, illustrated by 140 plates of 3,087 figures. 



During the last ten years of his life, Mr. Tryon wrote 5262 octavo 

 pages on conchology, illusti-ated by 1007 plates of 21,576 figures. 

 To the labor of composition the business cares of publication were 

 added : he was the publisher of his own works. 



Until his admission into the Friends' Central School, October 

 1850, whatever religious impressions he may have imbibed in child- 

 hood, if any, came from the Sunday School and the example and 

 teaching of his parents who w^re Lutherans. After leaving school, 

 June 1853, he became interested in the Society of Friends and reg- 

 ularly attended its meetings during several years. For reasons, no 

 doubt conclusive and satisfactory to himself, he left the meetings of 

 the Friends, and, from about the year 1876, he was usually present 

 at the stated services of the First Unitarian Church of Philadelphia. 

 When it was proposed, about 1883, to construct a new building for 

 the church Mr. Tryon was chosen one of its trustees. The work 

 interested him. He gave very generously ($1000) in aid of its com- 

 pletion. He was long chairman of the Society's committee on 

 music, and, until his death, was prominent among those who, in 

 various ways, actively promoted the interests of the church. 



He was not, however, rigidly sectarian. Knowing that there is 

 difference on every question that interests men, his natural spirit of 

 tolerance swayed his views and conduct relatively to those holding 

 opinions opposite to his own. 



He printed for private circulation, a pamphlet entitled. Church 

 and Stage, with the motto, Fiat justitia, mat ccelum. It contains 

 twelve octavo pages, and is dated March 15, 1880. 



The object of the paper is to uphold the drama as a proper means 

 of popular instruction in spite of its general condemnation by 

 clergymen. 



After stating substantially that, in western Europe as well as in 

 ancient Greece, the stage is the ofF-spring of the ceremonies of public 

 worship — that the mystery play, which followed the liturgical drama, 

 was the first form of the serious national stage in England, France,
