of Berlin ; August von Pelzeln, of Vienna ; Leonhard Stej- 

 neger, of Washington ; J. V. Barboza du Bocage, of Lisbon, 

 Dr. M. Menzbier, of Moscow ; and others. As a member of 

 a museum one has often a good opportunity of making a scien- 

 tific voyage — compare the hfe-histories of Th. Von Heuglin, 

 Dr. J. Biittikofer, Meves, and the long series of travelers 

 who published reports on such voyages as those of the Coquille, 

 Beagle, Erebus and Terror, Astrolabe, Novara, Challenger, 

 Plankton, etc. We may add those travelers who made their 

 long voyages in the discovery of unknown countries, Voila — 

 a long list of African explorers, many of whom were 

 sacrificed to science: Edouard Riippell, Francois Levail- 

 lant, R. Vierthaler, Baron J. W. Von Miiller, Brehm, 

 Fischer, Emin Pasha, and others. Photographs of many of 

 these men are very rare, and I am the happy owner of the 

 only copy of a portrait which exists of poor Vierthaler, who 

 traveled with A. E. Brehm, and was drowned in the 

 cataracts of the Nile,

 in the cold meadows of Iceland, E. L. Layard among the 

 Boers of South Africa, F. H. Von Kittlitz circumnavigating 

 the globe, and Briiggemann mounting the unknown hills of 

 Jara. We admire the energy of Dr. Gustav Ferdinand 

 Radde and Schrenck on their explorations in Russia; of 

 John Wolley, who thrice left comfort and civilized life to 

 find the eggs of the Waxwing {Ampelis garrulus) in the 

 desert plains of Finland, and we are happy to accompany, 

 in reading their interesting sketches, the travelers, T. H. 

 Kriiper to the old God's home, Olympos ; Brehm to the 

 vast tundras ; Schauer to the retired Karpathian moun- 

 tains ; N. Severtzoff in the Transcaspian and Uralasian 

 countries ; and Pere David among the Chinese. Other 

 travelers are fortunate enough to be able to spend their
