The greaterpart of the gas-lamps were ornamented by frozen stalac-tites, which continually attracted the attention of passers-by. The formation of these stalactites, of which we givea specimen, is easy of explanation. The snow falling onthe glass of the lamp became heated by the flame of gas, ICICLES ON THE LAMP. 29 melted, and trickled down, freezing anew into the shapeof a stalactite below the lamp, at a temperature of 0°centigrade. Not only can meteorology be studied intowns, but certain other branches of natural science—entomology, for example. We will quote what a young. Icicles on gas lamp. student in science, M. A. Dubois, says on this verysubject : Coleoptera, he declares, are to be met witheverywhere, and I think it may be useful to notice thisfact, supporting it by examples. I desire to prove thatthere are in the midst of our large towns spots thatremain unexplored, where some fine captures are to be 30 OPEN-AIR SCIENCE. made. Let us visit, at certain times, the approaches tothe quays, even at low tide, and we shall be surprisedto find there species which we have searched for far andnear. This opinion is confirmed by the enumerationof several interesting captures. Was not the great Bacon right when he said, For thekeen observer, nothing in Nature is mute ?
