PAUL LEVERKUHN, M.D. 205 



Austria ; Gadamer for the melancholy plains of far Sweden ; 

 Hagerup for the snowy camps of Greenland ; Brusina for 

 the rich Slavonian morasses ; Mojsisovics for those of 

 Southern Hungary ; Baron Droste for the poetical island of 

 Barkum ; and the long company of untiring explorers of the 

 empire of India: Edward Blyth, W. E. Brooks, B. H. 

 Hodgson, John Gould, T. C. Terdon, Przwalski, Stoliczka, 

 and many others. 



I must say for my excuse that in this short article, written 

 in haste at a distant point of Bulgaria, without any books, 

 and only from memory, by no means all those are enumer- 

 ated who are represented in my gallery ; and on the other 

 hand, that there are many stars of whom either no portrait 

 exists, such as Gilbert White of Selborne, or who are not 

 yet represented in my collection, as for example many 

 American authors. I should be very glad indeed if any of 

 my transatlantic brethren would, when reading this modest 

 memoir, fill up the gap. 



At the end I give a list of all my portraits, except those 

 contained in Anatol Bogdanow's large work, Scriptores 

 Rerum Naturalium Rossici, printed for private circulation, 

 in the Russian language, in which not less than 300 Russian 

 naturalists figure.
