of view, and it anticipated much that has since been written. The 

 last important paper he published was on a Cretinoid Condition in 

 Adult Women. It announced in succinct and modest fashion the 

 discovery of a remarkable form of disease, up to that time quite 

 unrecognised, and the accuracy of its description as well as the 

 justice of its pathological views have since been entirely confirmed. 



Foremost among clinical physicians of his time, and eminent 

 among the pathologists, remarkable for the breadth of his views, the 

 liberality of his conduct, and the native force of his character, Sir 

 William Gull occupied an eminent position during his life, and has left 

 a record of work which worthily answers to his great reputation.

STEPHEN JOSEPH PERRY was born in London on August 26th, 1833. 

 His early education was received at Gifford Hall School, from whence 

 he went to the Benedictine College at Douay, and then to Rome to 

 study for the priesthood. Resolving to join the Society of Jesus, he 

 returned to England, and on November 14th, 1853, entered on his 

 novitiate, and after two years went to France, where he stayed for a 

 year, returning to Stonyhurst to enter upon a course of mental 

 philosophy and physical science. His great ability in mathematical 

 studies decided his superiors in the Order to allow him to devote 

 himself specially to this branch of study, with the result that he 

 stood sixth on the Mathematical Honours List of London University in 

 1858, during which year he attended lectures by De Morgan at 

 London, and by M. Bertrand and others at Paris. On his return to 

 Stonyhurst in 1860 he was appointed Professor of Mathematics and 

 Director of the Observatory, which posts he filled for three years, 

 when he went to St. Beuno's College, North Wales, to complete his 

 theological studies previous to his ordination as priest, in 1866. 



In 1868 he resumed his work at Stonyhurst as Professor and 

 Director of the Observatory, and continued there until his death, only 

 leaving the College to take part in scientific expeditions. 



Previous to the appointment of Father Perry to the directorship, 

 the work done at Stonyhurst Observatory had been chiefly meteoro- 

 logical and magnetic ; it was selected as a first-class meteorological 

 station in 1866. 



In 1867 the astronomical department was much extended, more 

 powerful instruments were acquired, and the work undertaken very 

 much increased. Spectroscopy was commenced at Stonyhurst in 

 1870, and since then has formed a large portion of the astronomical 

 work carried on there. In 1872 regular observations of the phenomena 

 of Jupiter's satellites were begun with the 8-inch Troughton and 

 Simms equatorial, and with one considerable break, 1875 77, have 

 been continued up to the present time.
