II. — Notices of Fellows, Honorary and Ordinary, recently 
deceased. By The General Secretary. 
Emile-Hilaire Amagat was born in 1840. When Professor of Physics 
at l’Ecole Normale at Cluny, he began in 1867 his investigations of gases 
under high pressures. Later at Lyons, where he was Professor at the 
Catholic University, he utilised the tower of one of the churches as the 
site for a manometer giving pressures up to 80 atmospheres, and later 
constructed in one of the coal mines of St Etienne a Boylean tube measur- 
ing up to 430 atmospheres. In some of his experiments he applied with 
great success a suggestion of Tait’s for recording volumes by means of 
mercury coming in contact with platinum wires at different heights in the 
tube. His results in the gaseous laws for hydrogen, nitrogen, and carbonic 
acid and other vapours are recognised as the most authoritative we have. 
He was elected an Honorary Fellow of the Royal Society of Edinburgh 
in 1897, and died at his country estate at St Satur in the Departement of 
Cher in March 1915. 
George Friedrich Julius Arthur Auwers was born at Gottingen on 
September 12, 1838. He began his astronomical career at the Observatory 
of Gottingen, and in 1859 became assistant at Konigsberg. In 1862 he 
was transferred to Gotha, and finally in 1866 was appointed to Berlin. 
In his early days he made many excellent observations of variable stars 
and of double stars, and investigated very fully the irregularities in the 
proper motions of Sirius and Procyon. His re-reduction of Bradley’s 
observations occupied him ten years, and formed the foundation for his 
great catalogues of stars, for which he was awarded the gold medal of the 
Royal Astronomical Society in 1888. 
Auwers took a large share in the observations of the transit of Venus 
in 1874 and 1882, and visited South Africa in 1889, when he shared with 
Gill the observations of Victoria for the determination of the solar parallax. 
He was elected an Honorary Fellow of the Royal Society of Edinburgh 
in 1900, and died on January 24, 1915. 
Paul Ehrlich was born on March 14, 1854, at Strehlen, in Silesia, 
and was educated at Breslau and at Strasburg, where he graduated in 
medicine. . Since 1896 he has been Director of the “ K. Institut fur Experi- 
mentelle Therapie ” in Frankfurt-am-Main. Throughout his early career 
he took the deepest interest in the chemical relationships of living matter
