The Horn of the Indian Rhinoceros iJ/owatfe.— Interested, like very many others, 

 in the curious feat of self-mutilation performed by the male rbinoceros at the Zoo, I 

 paid him a visit on Saturday, August the 27lh, expecting to see the horn itself 

 adorned with a label notifying the paniculars of so extraordinary an event: in this I 

 was disappointed ; but I made an observation on the female rhinoceros which was so 

 new and interesting lo me that I think it worth recording. It has long been observed 

 by all who habitually frequent these gardens, that this horn topples forward over the 

 creature's mouth, and has thus assumed a very extraordinary appearance; but it has 

 not been recorded, or I should perhaps say that I have seen no record, of the horn 

 being moveable, not perhaps at the will of the animal, or by the assistance of any 

 muscles connected with the horn, but by the application of some external power, such, 

 for instance, as that of a man's hand. I saw this phenomenon exhibited several times 

 hy a visitor at the gardens, and it was very evident that the horn was loose, ]nsi in the 

 same sense as we speak of a loose tooth. It is, I believe, an opinion now universally 

 received, that the material of which the horn is composed is exactly the same as hair, 

 that It IS in fact neither more nor less than conglomerate hair ; but there is nothing in 

 this to induce the belief that it could be moved independently of the head, and indeed 

 independently of the skin, for as the operator rocked the horn very gently lo and fro 

 a slight fissure became evident between the base of the horn and the skin immediately 

 surrounding ,t, so that it not only seems probable that this creature may shortly 

 become hornless, like its mate, but it suggests the idea that the horn of the rhinoceros, 

 like that of the stag, may be deciduous and renewable. In connection with this subject 

 the lollowing note by a well-known zoologist will be found highly interesting: it is 

 extracted from the ' Field' newspaper of the 10th of Scptember.-^rf.rarrf Newman.
