GEOEGE STEWARDSON BRADY, 1832—1921. 



G. S. Brady, M.D., M.R.C.S., D.Sc, LL.D., F.R.S., C.M.Z.S., Professor of 

 Natural History, Armstrong College, Newcastle-upon-Tyne, and Consulting 

 Physician to the Sunderland Infirmary, was born, he told me, April 18th, 

 1832. Presumably also on his authority we learn that the event occurred 

 at Gateshead, and that he was the eldest son of Henry Brady, surgeon. 



As his childish education began at the Friends' School, Ackworth, it is not 

 improbable that he owed the name Stewardson to his parents' acquaintance 

 with the Quaker family which gave the popular portrait-painter of that name 

 to the early part of the nineteenth century. Certainly the whole tenor of 

 Brady's life seems to have been in tune with the principles of that peace- 

 loving community, and even on the scientific side there are many indications 

 that friendship was his delight. It has been already explained in ' Nature ' 

 (January 5th, 1922), among other details, that he became a member of the 

 Tyneside Naturalists' Field Club in 1849. At that early period it is said that 

 his interest was " with algae and other plant groups." Much later on he 

 referred to these studies when pointing out in correspondence (November, 

 1902), that the organisms which I had described as gland-cells in the amphipod 

 genus Urothoz, were, in fact, " parasites, probably algae." 



With the Natural History Society of Northumberland, Durham, and 

 Newcastle-upon-Tyne, of which the Tyneside Field Club was a branch, Brady 

 had a long and distinguished connexion, both as a frequent contributor to its 

 ' Transactions,' and twice President of the Field Club. The respect felt for him 

 by fellow- workers in systematic zoology may be partially traced by the use of 

 his name in classification. Thus among Copepoda Axel. Boeck names a genus 

 Bradya in 1872, Thomas Scott supplies Neobradya in 1892, Giesbrecht 

 Bradypontius in 1895, and Bradyidius in 1897, Vanhoffen Bradyanv.s in the 

 same year, and G. 0. Sars Pseudobradya in 1904. Sars had named a genus 

 Bradycinetus in 1865. But this suggests a curious need for caution in that 

 many generic names owe the commencing syllables Brady-, not to eminent 

 zoologists, but to the Greek /3paSv, indicating some organic slowness, and 

 very inappropriate to the scientific activities of George Brady and his 

 brother Henry. For the use of the former's name in identifying species, his 

 friend A. M. Norman led the way with the Ostracode Cylhere Bradii in 1864. 

 But this, for technical reasons, gave way to another species, the Marquis de 

 Folin's Cythere Bradii in 1869. Norman, in 1878, named a Copepod 

 Cervinia Bradyi, Sars in 1884 another of that group Undinopsis Bradyi, and 

 Thomas Scott a third in 1892 as Tetragoniceps Bradyi, but this, later on, he 

 found reason to place in a new genus with the long-flowing name of 

 Phyllopodopsyllus, strictly meaning " a leaf-footed flea," the species being 

 notable for " the large size and leaf-like form of the fifth pair of thoracic feet 

 of the female." In a footnote to Tetragoniceps Bradyi, Dr. Thomas Scott
