good fortune, whilst stationed in the north, to discover at Dur- 

 ness fossils that were the key to the geological age o£ the rocks 

 of the Highlands. 



A number of papers were communicated by Mr. Peach to the 

 British Association, the ' Annals and Magazine of Natural 

 History,' and to the publications of the three well-known County 

 Societies of Cornwall. Although he wrote comparatively little 

 himself, he was always ready to place bis knowledge and collec- 

 tions at the disposal of specialists ; and in this way furnished a 

 large amount of valuable material and information to many eminent 

 zoologists and palaeontologists, wliose cordial acknowledgments 

 are a lasting testimony to his zealous work and the service he 

 rendered to science. 



He was elected an Associate of this Society in 18G8. In 1859 

 the Council of the Greological Society awarded him the Wollaston 

 Fund in recognition of his discoveries in the rocks of Devonshire 

 and Cornwall ; and in 1875 the Eoyal Society of Edinburgh 

 gave him the Neill Medal, for his services in the cause of Natural 

 History. 



JoHANN" August Christian Eoeper was born in Germany, 

 some time in 1800 ; his first published work, on German Eu- 

 pho7'hicB, is dated 1S24, thus, as a botanical author, being senior 

 to Mr. Beutham by two years. In 1828 he was Director of the 

 Botanic Garden at Basel, and published his classical paper, " De 

 Organis Plantarum ; " his contribution to Seringe's ' Melanges 

 Botaniques,' on the Flower and Inflorescence, first put the 

 matter on a scientific basis, and established the present nomen- 

 clature. At that town he was Professor in 1830, the date of his 

 work on ' BMlsamine;e.' Some time before 1810 he was trans- 

 fei red to Rostock, where be remained professor for more than 40 

 years, without fulfilling the promise of his youth by any adccpiate 

 scientific work ; his latest productions seem to have been pub- 

 lished in 1859. He was elected Foreign Member, May 6, 1852, 

 and died at Kostock, March 17, 1884. 



Louis E£ne Tulasne was born at Azay-le-Eideau (Indre-et- 

 Loire), Sept. 12, 1815, received a classical education, and was 

 intended for the Bar; but he felt that he lacked the readiness for 

 public speaking which was indispensabie to his success as a bar- 

 rister, whilst a strong inclination towards biology drew him in 

 another direction. He studied botany under A. St.-Hilaire, who 

 named hun as his colleague in his work on the Brazilian flora, 

 which did not see the light. 



In 1842 he entered the Museum d'Histoire Naturelle as 

 Assistant, under Brongniart ; and then he began his researches 

 on the reproduction of Fungi, which so much contributed to the 

 existent knowledge of these forma. He published his researches 

 on UredmeiB in 1847, the Ustilaginea3 iu 1854, the Tremelliuese
