Eggs, when not fresh, are more or less liable to disease. I might even say more. When not fresh, they _are_ diseased. On this point we have the testimony of Drs. Willich and Dunglison. The truth is, that the yolk of the egg has a strong tendency to decomposition, and this decomposing or putrefying process _begins_ long before it is perceived, or even suspected, by most people. There is much reason for believing that a large proportion of the eggs eaten in civic life,--except when we keep the poultry ourselves,--are, when used, more or less in a state of decomposition. And yet, into how many hundred forms of food do they enter in fashionable life, or in truth, in almost every condition of society! The French cooks are said to have six hundred and eighty-five methods of cooking the egg, including all the various sorts of pastry, etc., of which it forms a component part. One of the grand objections against animal food, of almost all sorts, is, that it tends with such comparative rapidity to decomposition. Such is at least the case with eggs, flesh, and fish of every kind. The usual way of preventing the decomposition is by processes scarcely less hurtful--by the addition of salt, pyroligneous acid, saltpetre, lime, etc. These, to be sure, prevent putrefaction; but they render every thing to which they are applied, unless it is the egg, the more indigestible. It is a strange taste in mankind, by the way, which leads them to prefer things in a state of incipient decomposition. And yet such a taste certainly prevails widely. Many like the flesh beaten; hence the origin of the cruel practice of the East of whipping animals to death.[22] And most persons like fresh meat kept till it begins to be _tender_; that is, begins to putrefy. So most persons like fermented beer better than that which is unfermented, although fermentation is a step toward putrefaction; and they like vinegar, too, which is also far advanced in the same road. That diseased food causes diseases in the persons who use it, needs not, one would think, a single testimony; and yet, I will name a few.
