The slight falcon takes up his abode every year, from October and November until the spring, upon Westminster Abbey, and other churches in the metropolis. This is well known to the London pigeon-fanciers, from the great havoc they make in their flight.--_Sir John Sebright_ _Technicalities of Science_. The inutility of science, written in a merely technical form, is well exemplified in the instance of Cicero. He was advised by his friends not to write his works on Greek Philosophy in Latin; because those who cared for it would prefer his work in Greek, and those who did not would read neither Greek nor Latin. The splendid success of his _De Officiis_, his _De Finibus_, his _De Natura Deorum_, &c., showed that his friends were wrong. He persevered in the popular style, and led the fashion.--_Mag. Nat. Hist._ _Doubtful Discoveries_. It may serve, in some measure, to confirm M. Dutroehet's recent opinion of the non-existence of miscroscopic animalcula, that the celebrated Spallanzani persuaded himself that he could see Animálcula infusòria which could be seen by nobody else. He attributed his own superiority of vision, in this respect, to long practice in using the microscope. The philosopher exulted in his enviable distinction, when a peasant, to whom he showed his animalcula, could perceive nothing but muddy water.--_Ibid._ _Faculties of Brutes_. The dog is the only animal that dreams; and he and the elephant the only animals that understand looks; the elephant is the only animal that, besides man, feels _ennui_; the dog, the only quadruped that has been brought to speak. Leibnitz bears witness to a hound in Saxony, that could speak distinctly thirty words.--_Medical Gazette._ _Sea Air_. The atmosphere, in the vicinity of the sea, usually contains a portion of the muriates over which it has been wafted. It is a curious fact, but well ascertained, that the air best adapted to vegetables is pernicious to animal life, and _vice versa._ Now, upon the sea-coast, accordingly, animals thrive, and vegetables decline.--_Hurwood's Southern Coast._ * * * * * Chingford Church.
