Professor Gravenhorst, the author of a great monograph on 

 the Ichneumon Flies (' Ichneumonologia Europsea'), one of the 

 most difficult and extensive groups of insects, was born at 

 Brunswick in 1777, and died in 1857 at Breslau, as Professor of 

 Natural History, and Director of the Zoological Museum of the 

 University ; in addition to which he held the rank of Privy 

 Councillor. He studied at Helmstadt and Gottingen, and took 

 his Doctor's degree at the former place in 1801 ; and in 1811 he 

 was appointed Professor of Natural History at the University of 

 Frankfort-on-Oder, which, however, was transferred to Breslau 

 in the same year, where he continued his scientific work for the 

 rest of his life. 



On August 7th, 1851, the fiftieth anniversary of his doctorate 

 was celebrated at Breslau. The Curator of the University, 

 Upper Privy Councillor Heinke, and deputations from the 

 Senate, and from the Philosophical and Medical Faculties, 

 assembled at Prof. Gravenhorst's house, where Herr Heinke 

 invested him with the Order of the Bed Eagle of the third class, 

 with the sash, on behalf of the King of Prussia. The deputations 

 then congratulated the Professor on the occasion ; and he received 

 a renewal of his Doctor's diploma from the Philosophical Faculty 

 of the University of Gottingen, and the honorary degree of Doctor 

 of Medicine from the Medical Faculty of the University of Breslau. 

 Eector Barkow presented Prof. Gravenhorst with a congratulatory 

 address, and with a new work, ' ZootomischeBemerkungen,' which 

 he had just dedicated to him in honour of the occasion. Other 

 addresses were then presented from the students of the University, 

 the Silesian Society for National Culture, and the Entomological 

 Society of Stettin. 



In the afternoon the festivities terminated with a banquet, at 

 which several congratulatory poems were recited. One of these,
