It will be seen from these tables that a large proportion of carbon, hydrogen, oxygen, nitrogen, and earthy matters are again returned to the soil. From this we infer that more of these matters being present in the food than were requisite for the purpose of assimilation, they were removed from the system in the form of excrement. Two suggestions here present themselves for the consideration of the farmer, viz., that the manure increases in value in proportion to the richness of food, and that more of the latter is often given to a cow than is necessary for the manufacture of healthy chyle.
