of the Museum to the Science and Art Department, held the post of 

 Director till his death in September, 1881, his services thus extending 

 over thirty years. His assiduity in performing the duties entailed on 

 him in that office was not more remarkable than his care and skill as 

 a naturalist. His Paper in the Philosophical Transactions on the ana- 

 tomy of BalcBnoptera rostrata, written in conjunction with Professor 

 Macalister, the present Secretary of the Academy, is probably the 

 best known of his contributions to Biological Science. To the 

 Proceedings of the Academy he contributed, in conjunction with Mr. 

 E. J. Moss, M.E.i.A., a Eeport on the Animal Eemains found in the 

 Bog of Ballybetagh, near Dublin ; and to the Journal of the Eoyal 

 Dublin Society, papers on the Extinct Cave Animals of Ireland. By 

 the surgical profession, Dr. Carte will be remembered as the ingenious 

 inventor of an elastic compress for aneurism. 



Another valued Member of Council, and former Vice-President of 

 the Academy, has been lost to the Academy, in Dr. Thomas Hayden. 

 Dr. Hayden was appointed in 1854 to the Chair of Anatomy and 

 Physiology in the Faculty of Medicine of the Catholic University, 

 which post he continued to hold until his death. In 1866 Dr. Hayden 

 read before the Academy a Paper on " The Physiology of the Protrusion 

 of the Tongue ;" and, in 1871, a Paper discussing the effects of " The 

 Eespiration of Compressed Air." His attention subsequently was more 

 devoted to pathological than to physiological studies, and the result of 

 his researches in this direction became manifest, in 1875, in the publi- 

 cation of his work on *' Diseases of the Heart and Aorta." 



Eeuben J. Harvey (son of Joshua E. Harvey, m.d.. Professor of 

 Midwifery in Queen's College, Cork), was born in 1845, and educated 

 in Trinity College, Dublin, where he took high mathematical honors, 

 graduating as Gold Medallist and Senior Moderator in Mathematics. 

 Having studied Medicine in Trinity College, where he took the first 

 Medical Scholarship (1868), he proceeded to his m.b. degree in 1870 ; 

 and subsequently, after studying at Wiirzburg, he became Demon- 

 strator of Anatomy in the Dublin University Medical School. In 

 1872 he was made Lecturer in Physiology in the Carmichael Medical 

 School. He was the author of several Papers on Physiology, one of 

 which " On the Intertubular Tissue of the Mammalian Testis," will 

 be found in our Transactions, vol, xxvi.. Science, part 2.
