I was told by an Englishman who had resided long in Egypt of one who had become the owner of a farm, well stocked, and possessing some of the latest improve ments. Among other things, he had a steam-engine, which he used for some work on his farm. Having gone to visit it, he found occasion to speak sharply to the raau who was in charge of it. Although an Egyptian, this engi neer acquired some notions Avhich were too independent to suit the taste of this pampered favourite, and he replied rather saucily to his master. This so enraged him that he wont quickly into his house, seized a sword, and returning to the engineer, wreaked his vengeance on him by smiting him to the ground.

scientific men collected tho facts, co-ordi nated them, and reduced them to the domain of law. We owe much of the beauty of our gardens to the practical skill of the florist in perpetrating varieties. The many hun dred fuchsias, for instance, have been pro duced from the siugle type almost within the memory of men now Hying. The Gipsy pigeon fanciers of tho suburbs of London were at work long before Darwin or Wallace was born. Bakewcll produced his improved short horns at a period quite as early. He observed that cattle of a certain form, which he called "ribbed-horn" (that is as exhibit ing the greatest departure from the form of the greyhound or the race-horse) had a tendency to fatten and to early maturity. In all these cases tho breeder takes advantage of the laws of Nature. Darwin dili gently collected all the known facts observed by others, because a most patient and diligent observer of facts him self, and <xt length geiieraJised them into his -well -known essay on the " Origin of Species." Even in his more recent work on the " Descent of Man," he does not push his conclusion beyond species. But Hackel goes far beyond this.
