If, on the contrary, one takes the cows raised on a poor soil, transfers them to rich pastures, the milk produce of these same cows will be superior to that they gave in their original lands.

My readers should well understand that in the valuations of my classifications that I have not pretended to assign a rigorous and absolute amount. I have been only able to give an approximate figure to each class and to each order, adopting the medium limit of the ordinary amount of the different breeds of various localities.

The atmosphere, the care, and the different foods of each country, all these different things exercise upon the animal, an influence favorable or unfavorable, according to the nature of the soil.

There are many other circumstances which should be considered, and which would disturb the harmony of the figures of my valuation and the normal quantity. Such are, for example, the case of sickness, accidents, &c. That is the reason I have adopted, in determining the quantity of cows of each order, a medium figure, such as is shown in the classification.

I will also observe, relative to those animals to which I assign approximate weight in the course of this work, that, following the customs of commerce, of sale, and of butchers, this weight is dead weight, the animal being deprived of the skin, intestines, head, feet, &c.

If, contrary to custom, I had acted otherwise, and had made the calculation for the animal on the hoof, the figures given by me would present a great difference, which would increase according to the amount of fat, sometimes to double the weight.

The discovery which I have made of the value of the escutcheon is designated by the contrary direction of the hair, and which had escaped the attention of every one, even those most interested in gaining the knowledge of it. It is necessary also to avow the effect produced by the change of direction of the hair is not glaring on the animal. It is merely a difference of luster, and the gloss on the surface of the escutcheon and the part of the skin surrounding it. The hair of the escutcheon is finer, shorter, more furry, and more silky. Its appearance, at the first glance, makes one think this part of the animal has been shaved. Compared with the ordinary hair, the skin of the udder appears to be more designed to be quicker seen on the part where appears the escutcheon.

All animals of the bovine species, without excepting even wild animals, are marked with an escutcheon, large, small, or medium, regular or irregular. Their characteristic sign is transmitted with the generating germ.

I have not thought it necessary to say much on that portion of the escutcheon which extends on the stomach of the beast towards the navel. This addition has been thought useless. Enough is shown of the escutcheon when she is standing.
