A REMARKABLE ACCUMULATION OF BATS. 409 supposed to be grandfathers, of a reddish hue, which was thought to be from age. These vermin are generally more or less covered with a small-sized bug not very dissimilar to the common chinch, but of a different species. As previously stated, the bat has a very disagreeable odor, which also pertains to its ejection. The manure as well as the bodies of the slain was used to fertilize the flower. ing and vegetable garden, and thus, in some degree, they served to compensate us for the annoyance to which we had been subjected. The manure, however, required to be applied with caution, since, if used in too large a quantity, it appeared to burn the organism of the plants. To remove the very disagreeable odor which remained in the upper part of the house, various kinds of disinfectants were employed with some advantage; but the most effectual method resorted to was that of opening holes of about four inches square, two at each gable end, to permit a current of air to pass through. These holes were covered with iron gauze to prevent the re-entrance of any of the remainder of the army of the enemy which might hover around the premises. At the end of five years the odor has now nearly disappeared, being barely perceptible during a continuance of very damp weather. [The fact mentioned above of the numerous parasites infesting bats is perhaps the most revolting feature in these creatures. The enormous population of Acari found upon their bodies is due to the great generation of animal heat in their close haunts, a condition conducive to a rapid increase of all kinds of vermin. In this country the common bed-bug (Cimex lectularis) is frequently found upon their fur. The entrance of a bat, with its precious burden, into the open window of a farm-house is the solution of that frequently propounded question of the despairing housewife, "Where can the bugs come from?"] 1.00000 parts of gas at 32 F., 29.922 bar., (also at 32°,) become, at 60° F., bar. 30 inches, (also at 60°) 1.05720 parts.
