FLIGHT OF UKANIA LEILUS AT PANAMA. 



The Panama Stm' and Herald of June 25 announces the 

 usual migration of the brilliant butterfly Urania leilus, and 

 which were so abundant as to appear in their flight like dried 

 leaves driven by the wind. As usual, their course was from 

 wxst to east ; but whence they came and whither bound has 

 not been ascertained. All the females caught were nearly 

 full of eggs. Panama Star and Herald^ June 25, 1873. 



AX AQUARIUM FOR CENTRAL PARK. 



The New York papers have contained quite a number of 

 articles urging the propriety of establishing an aquarium in 

 Central Park, equal to that of Brighton, in England. It is 

 much to be hoped that measures will be taken at an early 

 day for accomplishing this object. There is nothing more at- 

 tractive to the public than a well-arranged establishment, 

 where the diflerent marine objects may be seen in their na- 

 tive element. Distorted stuffed skins, or shriveled and offen- 

 sive preparations in alcohol, give but a very inadequate idea 

 of the appearance of the living objects which they attempt 

 to represent. If the Central Park authorities are unwilling 

 to go to the expense of erecting an establishment of this kind, 

 it may not be amiss for them to authorize it to be done by 

 private enterprise, a small fee being charged for admission. 

 The Brighton Aquarium, the largest and most elaborate yet 

 erected, is a pecuniary success, and there is no doubt that, in 

 a city like Xew York, the number of persons who w^ould visit 

 such a collection would be ample to support it on a large 

 scale, as it would be especially attractive to children, and a 

 means of education, by object-teaching, of the greatest value. 

 New York is favorably situated for securing all the varieties 

 of animal life belons-ino: to the sea. An abundance of water 

 can, of course, be readily obtained, while the fishing vessels 

 could easily be engaged to bring in some of their most inter- 

 esting captures, these to be supplemented by the results of a 

 special mission for the same object. The services of the
