the memory of the Naumann family by the erection of a 

 Museum in Cothen, wherein are to be deposited the Nau- 

 mann collection of birds with manuscripts, letters, pictures 

 and other relics. 



There were three ornithologists of this name. The father, 

 Johann Andreas Naumann (1744-1826), was born at Ziebigk 

 near Cothen, and was a landed proprietor, who devoted the 

 greater part of his life to the study of birds. 



His son, Johann Friedrich Naumann (1780-1857), also 

 born at Ziebigk, followed in his father's footsteps, and was 

 Professor and Inspector of the Ornithological Museum of 

 the Duke of Anhalt-Cothen. 



Another son of Johann Andreas — Karl Andreas — Was a 

 good field-ornithologist, but himself wrote but little. 



The elder Naumann's work has the following title : 

 " Naturgeschichte der Land- und Wasser-Yogel des nord- 

 lichen Deutschlands und angranzender Lander, nach eigenen 

 Erfahrungen entworfen und nach den Leben gezeichnet. 

 4 vols. Kothen, 1797-1803. 8vo. 



The plates for this work were drawn by Johann Friedrich. 



The work of the younger Naumann is entitled: — "Natur-
