 who was born in that city in 1823 and died

 eminence, and as president of the Academy 

 of Natural Sciences, professor of human and 

 comparative anatomy and zoology in the Uni- 

 versity of Pennsylvania, and president of the 

 Wagner Free Institute of Science, accom- 

 plished much for these institutions. The sum 

 of $10,000 is being collected for the memorial. 

 Contributions may be sent to Mr. Edward B. 

 Smith, treasurer of the Leidy Memorial Com- 

 mittee, 511 Chestnut Street, Philadelphia, Pa. 



We learn from The British Medical Journal 

 that in . connection with the centenary of the 



birth of Joseph Skoda the Vienna Medical 

 Society has decided to issue a complete edition 

 of the famous physician's writings. A com- 

 mittee has been formed for the purpose of 

 carrying this scheme into execution; it con- 

 sists of Professors Chrobak, von Schrotter, von 

 Neusser, Benedikt and Heitler, with Pro- 

 fessors Neuburger and Toply as representa- 

 tives of the historical sciences. In this edi- 

 tion will be collected Skoda's lectures in the 

 University of Vienna, the articles contributed 

 by him to medical journals, and the special 

 scientific opinions and judgments often deliv- 

 ered by him, together with the other published 

 works of the great clinician. 



We learn from Nature that a memorial to 

 the late Dr. George Salmon, F.R.S., provost 

 of Trinity College, Dublin, was unveiled on 

 Friday, Janiiary 5, in the national cathedral 

 of St. Patrick's, with which Dr. Salmon was 

 officially associated during the best years of 

 his life. An account of the ceremony ap- 

 peared in the Kensington Express of January 

 5, from which we learn that the memorial con- 

 sists of two windows in St. Peter's Chapel, the 

 work of Mr. C. E. Kempe, depicting scenes 

 in the career of St. Peter, and a medallion of 

 Dr. Salmon, by Mr. A. Bruce-Joy, with a 

 Latin inscription of which the following is a 

 translation : "That the name of George Sal- 

 mon may abide in the memory of mankind 

 this monument has been erected by his faith- 

 ful friends and grateful pupils. Fellow of 

 Trinity College, Dublin — afterwards regius 

 professor of divinity, and finally provost, he 

 was for thirty-three years chancellor of this 

 cathedral church. A mathematician both 

 adroit and powerful, he probed with keen in- 

 sight the beginnings of christian history, and 

 specially the origin of the New Testament 

 Books; as teacher and councillor he was un- 

 wearied in the serviiie of the Irish church. 

 Shrewd, courteous, serious, kindly. He was 

 born in 1819, and died in 1904. The fear of 

 the Lord is the distinction of wisdom, and be- 

 fore honor is humility." 



Dr. H. J. P. Sprengel, F.E.S., the inventor 

 of the mercury air-pump, died on January 14, 

 aged seventy-two years.
