ZOOLOGICAL GARDENS. 791 



ever, the entire quarterly report, as in it also will appear the en- 

 gravings and descriptions of hitherto unfigured animals, and a 

 general account of the quarterly proceedings of the entire estab- 

 lishment, and other matters of interest. 



Thus it will be seen that the prosectorial department is one 

 of the most important connected with the institution, and in due 

 time will contribute to the common stock of scientific knowledge 

 a mass of information of a peculiarly valuable character, and of 

 a kind, as a rule, not easily obtainable in any other way. 



Taken, then, in its entirety, a zoological garden, such as I 

 have attempted to outline in this paper, has within its means to 

 powerfully aid, encourage, and stimulate human progress, educa- 

 tion, and science in an infinite variety of ways ; and such an insti- 

 tution stands among the very best of investments to be made 

 either on the part of State or city. Here are library, lecture, art, 

 design, and interest for the multitude, and yet how rarely does it 

 occur to the mind of the philanthropist to make an endowment 

 in such a direction ! Moneys diverted into such channels not 

 only are given to the cause of education and learning and art, 

 but to the embellishment of the city where the garden is founded, 

 to the interest of its people, and the perpetuation of the name of 

 the donor. Zoological gardens, again, even exert a far more pow- 

 erful influence toward luring those of certain classes and con- 

 ditions away from the vices of a city than does the museum or the 

 library ; while, with others, it leads to a greater interest and appre- 

 ciation of the other establishments and their advantages. 



With respect to a nation as a whole that has arrived at a cer- 

 tain height of civilization, and can boast of a well-filled treasury, 

 it almost, if not quite, becomes her bounden duty to her people, 

 and to the common good, to endow such an institution at her 

 national capital, in connection with other scientific departments, 

 of which she is the supporter in chief. And it should be the 

 pride of every intelligent citizen of such a nation to see to it, as 

 far as he is individually able, that the capital of his country is 

 not backward in such matters, especially when he comes to look 

 about him and sees that the most distinguished and influential 

 nations of the earth are characterized by possessing just such 

 institutions at the seat of their national governments. 



The International Geological Congress map of northern Germany, which is 

 in proof, is to be printed in twenty-four different tints for the sedimentary forma- 

 tions, three for the archsean, and nine for the eruptive rocks, and will consist of 

 forty-nine sheets. One color is taken for each group — Cretaceous, green ; Juras- 

 sic, blue, etc. The subdivisions are shown by various modifications of these colors. 

 As a rule, the lower subdivisions are shown by the darker tints.
