On the trees at Burpetah, great numbers of the Vampire or Fox-bats are to be seen hanging by their claws with their heads downwards. They are offensive looking objects, having a body eleven inches long, and each wing twenty-two inches in length. I have never heard a native assert that they suck the blood of cattle when sleeping, and if it were the case, such a circumstance would certainly be quickly verified; it may therefore justly be inferred, that this is a popular error. It is said that the food of the fox-bat consists entirely of jungle fruits; their flesh is esteemed a delicacy by many natives, and I have frequently shot them to gratify the appetites of my own servants. There is a strange superstition amongst the natives, that the bones of the fox-bat, worn as an amulet or charm, will cure any limb or part of the body affected with pain. One of the most curious members of the animal (query, vegetable?) world in Assam is the Leaf insect--so called from its very close resemblance in form, colour, and general structure (even to the fibre), to the leaf of the tree which it inhabits. In fact, until the insect moves, it is difficult to distinguish it from the leaf itself. The annexed drawing will convey an idea of this singular freak of nature; many attempts at transmitting a perfect specimen to Europe have been frustrated by the perishable character of the insect. Spirits are entirely inefficacious as preservatives, and camphor destroys the colour of the animal. In perambulating the district, I was particularly struck with the immense extent of high grass jungle between the Burrampooter river and the foot of the Bootan mountains. I frequently traversed a distance of eight and ten miles through a dense grass jungle twenty feet high, without meeting with a solitary hut or any cultivation; but suddenly, a village and an open cultivated space of a few hundred acres would burst upon the view and vary the monotony of the scene. This would be followed by a dreary waste extending to the next village, often five or six miles distant; while a solitary foot-path, forming the only communication between the small communities thus isolated, clearly showed that for many months in the year little intercourse, except by water, is kept up between them.
