" The Royal Collection at Berlin having been recently re- 

 arranged, and the Royal Museum of Leyden, and the Museum 

 of the Senckenberg Society of Frankfort having been formed 

 within these few years, the greater part of the specimens are 

 quite fresh, and in the most perfect condition, and their history 

 is generally known, and accurately marked upon them. These 

 museums are the more valuable, as each of them is peculiar for 

 having the most complete collections from certain parts of the 

 world. That of Berlin excels in those of Buchara, of Mexico, 

 and of the Brazils ; while the Leyden Museum is richest in the 

 productions of the Dutch colonies, as the Islands of the Indian 

 Archipelago, the Cape, and Surinam. That of Frankfort con- 

 tains the most complete collections of the animals of Egypt, and 

 the rest of Northern Africa, that was ever brought together, 

 having been entirely formed by the exertions of Dr Riippell, 

 during his travels in those countries, and extended by specimens 

 received from other museums in exchange for his duplicates ; 

 yet this monument of the industry of an individual, must rank 

 very high amongst the museums of Europe. After having laid 

 before the scientific public the novelties which he has discovered, 

 Dr Riippell has again left Europe (at his own cost) to extend 

 still farther the empire of science. 



" I hardly know how sufficiently to express my thanks to 

 Herr Temminck and Herr Schlegell of Leyden ; to Professor 

 Lichtenstein, and Herr Deppe of Berlin ; to Drs Cretzrchmarr 

 and Riippell, and Senator Von Heyden of Frankfort for the 

 courtesy and attention which they shewed me during my visits 

 to the various museums under their direction; indeed with such 

 liberality, that it would be impossible, however desirable, to 

 imitate them in our more populous towns. In each of these 

 museums all the specimens were intrusted to me to describe, 

 draw, or examine them, as might best suit my purpose, without 

 any restraint, except that, at Leyden, Herr Temminck request- 

 ed that I would indicate in what museum I had seen it, and the 

 name under which it was described, — a rule which I hope I 

 have most faithfully kept. In Frankfort, some specimens were 

 even sent to my hotel, that they might be examined more at 

 leisure. I cannot here omit to mention the names of Sir James 

 MacGrigor, and Dr Burnet, for their kindness in allowing me
