singular habitation is composed of about twenty thorns, for the 

 exterior, lined with a coat of silk, similar to the cone of the silk- 

 worm, suspended to the tree by a strong ligament of the same 

 material. In this asylum the baubul caterpillar retires to its long 

 repose; and, armed with such formidable weapons, bids defiance 

 to birds, beasts, and serpents, which might otherwise devour it. 

 When the season of emancipation arrives, and the chrysalis is to 

 assume a new character in the papilis tribe, the insect emerges 

 from the fortress, expands its beautiful wings, and with thousands 

 of fluttering companions, released at the same season from captivity, 

 sallies forth to enjoy its shorted-lived pleasures. Paley has hap-

The baubul trees are also covered by pensile nests of the bay a, 

 or bottle-nested sparrow, which I have formerly described. These 

 birds seem to have formed immense colonies in the wilds of Tur- 

 caseer, and most of the Acacia forests in Guzerat; from fifty to
