"musk," from the queer little hornless musk deer, are 

 secretions of glands. It has been suggested that the 

 defenceless musk deer escapes many of its enemies by 

 the similarity of its secretion to the musky odour of croco- 

 diles. In many animals which live together in herds, such 

 as the antelope and deer, and which have neither bright 

 colours nor far-reaching calls to aid straying members to 

 regain the flock, there are large and active scent glands. 

 The next time you see a live antelope in a zoological park, 

 or even a stuffed specimen, look closely at the head, and 

 between the eye and the nostril a large opening will be 

 seen on each side, which, in the living animal, closes now 

 and then, a flap of skin shutting it tight. 



Among pigs the fierce peccary is a very social animal, 

 going in large packs; and on the back of each of these 

 creatures is found a large gland from which a clear watery 

 fluid is secreted. Dogs and wolves also have their odour- 

 secreting glands on the back, and the "wolf -pack" is 

 proverbial. 



The gland of the elephant is on the temple, and secretes 

 only when the animal is in a dangerous mood, a hint, 

 therefore, of opposite significance to that of the herding 

 animals, as this says, " Let me alone! stay away!" Certain 

 low species of monkeys, the lemurs, have a remarkable 

 bare patch on the forearm, which covers a gland serving 

 some use. 



If we marvel at the keenness of scent among animals, 

 how incredible seems the similar sense in insects similar 

 in function, however different the medium of structure 

 may be. Think of the scent from a female moth, so
