238 Obituary— Professor Neumayr. 



The " Petrefactenkunde Deutschlands " was Quenstedt's greatest 

 work ; the first volume was issued in 1849, and the eighth and last 

 in 1884: it has been calculated that there are no less than 19.029 

 specimens figured and described in this work. Jurassic palaeontology 

 is especially well treated in the Petrefacta, and also in Quenstedt's 

 '•' Handbuch der Petrefaktenkunde," the three editions of which 

 appeared in 1852, 1867, and 1885 respectively ; he made further 

 contributions to the knowledge of the fauna of the same system in 

 an extensive series of memoirs. The Cephalopoda was his favourite 

 group : it formed the subject of both his first and last paleeonto- 

 logical works, viz. his doctoral thesis in 1836, "De notis nautileaiuim 

 primariis," and " Die Ammoniten des schwabischen Jura," concluded 

 a few months before his death. But though palaeontology became 

 the chief woidc of his life, as was naturally the case with a geologist 

 living among the rich Jurassic rocks of Wurtemberg, Quenstedt did 

 not neglect his first love, mineralogy, and his " Methode der 

 Krystallographie" (1840), his well-known " Handbuch der Miner- 

 alogie" (1854, 1863, and 1877), and his "Grundriss der bestimmen- 

 den und rechnendeu Krystallographie" (1873), were his principal 

 publications upon this subject. Probably no German geologist 

 was more prolific of big books than Prof. Quenstedt, and the fact 

 that he accomplished so much is no doubt to be explained by his 

 retention in after-life of the indefatigable energy, the simple life, 

 and abstemious habits, which characterized him in his student 

 days. Born of the people, he was always in touch with them, 

 and he never used the title " von," which had been granted him ; 

 his popular works, " Sonst und Jetzt " (1856), " Epochen der 

 Natur " (1861), and " Klar and Wahr " (1872), showed how deeply 

 he felt the need of the popularization of scientific education. His 

 success in forming so valuable a collection from the Wurtemberg 

 Jura is probably as much due to the interest in geology spread by 

 his writings as to his own personal popularity with the people 

 among whom he lived so long and laboured so well. 



MELCHIOR NEUMAYR. 



Born 24th October, 1845; died 29th January, 1890. 



Melchior Neumayr was born in Munich on 24th October, 1845, 

 but spent most of his childhood in Stuttgart, where his father was 

 the Bavarian Ambassador. As the son of a family that has borne 

 an honoured name in the annals of Bavarian history, Neumayr was 

 destined for political service, and after leaving the Gymnasium 

 of Munich, he commenced a course of legal studies in the Uni- 

 versity of that city. Here, however, his enthusiasm for science 

 manifested itself, and led him to abandon law for geology and 

 palaeontology, the better to study which he proceeded to Heidelberg. 

 After gaining his Ph.D. at this University, he returned to Bavaria, 

 and worked under Giimbel on the geological survey of that state. 

 After a few months' training he joined in 1868 the service of the 

 Austrian Geologische Keichsanstalt as a volunteer ; in the same year
