“T beg leave to exhibit a drawing of the present state of the horn of our old female 
Rhinoceros, which has now been in the Gardens since 1850 (fig. 1). Instead of rising

been sent home as a present by Mr. A. Grote; the female was purchased for us by

Commissioner of that province. 
Having already a female R. wnicornis in the Menagerie, the Council determined to 
part with the second example of the same sex thus acquired, and, in 1865, exchanged 
her with the Jardin des Plantes, Paris, for an African Elephant. The male remains 
still in our Gardens in excellent health and condition, and is the original of the water-
