dually associated with a large number of scientific Societies through- 

 out the world. His election as a Foreign Member of the Linnean 

 Society took place in 1824, and he died on the 19th of June 1844. 

 A mere list of his zoological writings would occupy a considerable 

 space. Besides a number of important papers in the ' Annales ' and 

 • Memoires du Museum d'Histoire Naturelle,' in the ' Bulletin de la 

 Societe Philomathique,' in the ' Annales des Sciences Naturelles/ in 

 the ' Dictionnaire des Sciences Naturelles,' and in other scientific 

 miscellanies, he published separately several works which have con- 

 tributed in no small degree to the progress of zoological and anato- 

 mical science. Among these the most important is his ' Philosophic 

 Anatomique,' in two vols., published in 1818 and 1823 ; the first en- 

 titled ' Des Organes Respiratoires sous le rapport de la determina- 

 tion et de I'identite de leurs pieces osseuses,' the second ' Des Mon- 

 struosites Humaines.' In this work he endeavours to demonstrate 

 throughout the animal kingdom a uniform plan of organization, re- 

 cognizable by the existence, not of the same organs, but of the mate- 

 rials of the same organs in all. From the period of the publication 

 of his ' Philosophic Anatomique,' this " unity of composition " be- 

 came the leading idea of all his writings. It was the subject of a 

 lengthened discussion between him and Cuvier ; and presides over 

 his ' Systeme Dentaire des Maminiferes et des Oiseaux,' published 

 in 1824, his ' Considerations Generales sur les Monstres,' in 1826, 

 his ' Cours de I'Histoire Naturelle des Mammiferes,' of which only 

 one volume appeared in 1829, as well as over numerous notes and 

 memoirs on the structure of Marsupialia and Monotremata, published 

 at various times. To him, conjointly with Cuvier, France is indebted 

 for the elevated position in zoology which she has occupied for the 

 last half century. Following up with equal zeal and success the 

 career of anatomical investigation opened for them by Daubenton, 

 Vicq d'Azyr and others, and adding to the habits of minute inves- 

 tigation of those excellent observers a spirit of philosophical genera- 

 lization, these two great zoologists created a school in which the 

 study assumed a really scientific character. From this school have 

 emanated the most valuable contributions that zoology has received 

 in our times, and it will long continue to exercise a salutary influ- 

 ence over the labours of succeeding generations. 



Karl Bernhard von Trinius was born at Eisleben on the 7th of 

 March 1778. He devoted himself at an early age to the study of 

 botany, and especially of the grasses, on which he published nume- 

 rous highly important works. Of these the principal separate pub- 

 lications are : ' Fundamenta Agrostographiae, sive Theoria construe-
