Felis tigris Buff. Bengal Tiger. The music had a peculiar effect on the 
pair of animals in this cage. The male paid absolutely no attention to it, 
save glancing in the direction of the player and giving a vicious snarl. 
‘The female, however, acted as though she liked it, for she jumped upon 
a shelf and placed her paws and nose through the bars as described 
under the last species. A second experiment with the male, later, when 
he was stretched out upon the floor of the cage, caused him simply to 
look at the player, twitch his ears, and viciously spit and snarl at him. 
The female, however, on all occasions showed that music was not dis- 
tasteful to her and that it was, on the whole, pleasing. 
Hyena vulgaris Buff. Hyena. This animal is probably the most 
cowardly of all the mammals, and the only effect which music had upon 
two individuals was to cause them to retreat to the farther end of the 
cage and try to squeeze out between the bars. A lively jig frightened 
them nearly to death, and made them tremble in every limb. Strange 
to say, however, they did not howl or make the least noise. 
Quadrumana. The Monkeys. (Genus Cynocephalus.) The mon- 
keys evidenced great curiosity at the music, but did not seem to show 
either pleasure or displeasure at the sounds. A South American Sooty 
Mangabey, however, seemed to be rather pleased with the strains, par- 
ticularly the jigs. This animal is of a quarrelsome disposition, and is 
therefore kept separate from the other monkeys. It was thought by Mr. 
Sweeney, the keeper, that the sounds might awaken a feeling of anger 
in him, but such was not the vase. As the violinist drew away, he fol- 
lowed as far as his cage would allow. A spark of reason was observed 
in this animal. His cage is of glass all around, and in order to hear the 
music better he placed his ear to a crack inthe door. ‘This he did sev- 
eral times as the player drew near or went farther from the cage. The 
monkeys confined in the larger cage, also of glass, formed themselves in 
a broken semi-circle about that part of the cage nearest the violinist, 
and looked at him in apparent wonder. As he moved away from them, 
they arose from their sitting posture with one accord and followed him 
along the side of the cage. This was probably simply curiosity, although 
the music may have given them some pleasurable sensations. On the 
whole, the monkeys did not show as much intelligence as might have 
been expected from their high position in the scale of nature. 
Pilecanus fuscus Linné and P. erythrorhynchus Gm. Brown and 
White Pelicans. The pen containing these birds is situated next to the 
monkey cage, and the music was next tried upon them. The effect was 
somewhat startling, for they all began to jump about, flap their wings, 
and snap their huge beaks; this might, perhaps, be called dancing.
