74 NATURAL SCIENCE. July, 1894. 



experiments on an extensive scale, that, had they not been stopped 

 by his untimely death, would have been of great importance in settling 

 many obscure questions of inheritance. Certainly English science is 

 the poorer for the death of this worker, who gave so much time, 

 talent, and ability to the investigation of its more abstruse problems. 

 We are indebted to the courtesy of the Editor of the Illustrated 

 London News for the portrait here given. 



Dr. August von Klipstein, whose death, on the i6th of April 

 in this year, we recorded in our last number, was the son of the 

 mineralogist, Philipp Engel von Klipstein, of Darmstadt, and was 

 born on June 7, 1801, at Hohen-Solms, near Giessen. In 1836 he 

 was appointed Professor of Mineralogy at Giessen. He is perhaps 

 best known by his monograph on the geology and palaeontology 

 of the Eastern Alps, but has also made valuable communications on 

 the geology of the Kupferschiefergebirge, the Odenwald, the 

 Dukedom of Hesse, Upper Suabia, and the Vogelsgebirge. In 1837 

 he described, with J. J. Kaup, the Dinothcvium giganteiim from 

 Darmstadt. 



Dr. Jozsef Szabo de St. Miklos, who, as already announced, 

 died at Budapest on April 10, at the age of 73, was well-known 

 for his studies in mineralogy, of which science he held the chair in 

 the University of Budapest. He was also President of the 

 Hungarian Geological Society, and secretary to the Natural Science 

 section of the Hungarian Academy. Dr. Szabo was an enthusiastic 

 collector, and the University Museum owes much to his energy and 

 exertions. 



Dr. K. a. Fiedler, Privatdocent at the University of Zurich, 

 died on April 2, at the early age of 31. Dr. Fiedler had published, 

 among other things, some interesting experiments on the development 

 ■of Echinoderm eggs similar to the experiments of Driesch, Herbst, 

 and others. 



We have also to record the deaths of the algologist, Alphonse 

 DERBfes, Honorary Professor at the Faculty of Science at Marseilles ; 

 of Dr. Thomas Morong, Curator of Columbia College, who died on 

 Thursday, April 26. Dr. Morong was especially known for his 

 work on Potamogetons and other allied water plants ; he also 

 collected somewhat extensively in Paraguay. And of Knut Fredrik 

 Thedenius, at Stockholm, on March 4, aged 80. An apothecary 

 and a teacher of Natural History in the Stockholm Gymnasium, 

 Thedenius was the author of several works on Swedish local floras, 

 and also, in conjunction with N. J. Andersson, of a " Svensk Skol- 

 Botanik," containing 250 coloured plates and descriptions of Swedish 

 .plants.
