against that rule of philosophy, which teaches us to ascribe like effects to like causes, should we impute this diminution of size in America to any imbecility or want of uniformity in the operations of Nature. It may be affirmed with truth that, in those countries, and with those individuals of America, where necessity or curiosity has produced equal attention as in Europe to the nourishment of animals, the horses, cattle, sheep and hogs of the one continent are as large as those of the other. There are particular instances, well attested, where individuals of this country have imported good breeders from England, and have improved their size by care in the course of some years. To make a fair comparison between the two countries, it will not answer to bring together animals of what might be deemed the middle or ordinary size of their species; because an error in judging of that middle or ordinary size would vary the result of the comparison. Thus Monsieur D'Aubenton considers a horse of 4 feet 5 inches high, and 400 ℔ weight, French, equal to 4 feet 8.6 inches, and 436 ℔ English, as a middle-sized horse.[1] Such a one is deemed a small horse in America. The extremes must therefore be resorted to. The same anatomist dissected a horse of 5 feet 9 inches height, French measure, equal to 6 feet 1.7 English.[2] This is near 6 inches higher than any horse I have seen; and could it be supposed that I had seen the largest horses in America, the conclusion would be, that ours have diminished, or that we have bred from a smaller stock. In Connecticut and Rhode Island, where the climate is favorable to the production of grass, bullocks have been slaughtered which weighed 2,500, 2,200, and 2,100 ℔ nett; and those of 1,800 ℔ have been frequent. I have seen a hog[3] weigh 1,050 ℔ after the blood, bowels and hair had been taken from him. Before he was killed an attempt was made to weigh him with a pair of steelyards, graduated to 1,200 ℔, but he weighed more. Yet this hog was probably not within fifty generations of the European stock. I am well informed of another which weighed 1,100 ℔ gross. Asses
