Mouth treatment of food, which permits, aids, and includes insalivation (mixing with saliva), and which is both actively digestive in its functions and preparatory to final digestion, is the only actual mechanical responsibility we have in our nutrition; and, in connection with favourable A conditions, insures perfect digestion. It has been so fully and clearly explained in some recent articles, "Observations on Mastication," by Dr. Harry Campbell, F.R.C.P., physician to the Northwest London Hospital, printed in the "Lancet" of July nth, 18th, 25th, and August 8th, 1903, that reference to the articles, reprinted herewith, is all that is necessary here.

In giving attention to careful mouth-treatment of soft or liquid foods until they are absorbed by the Swallowing Impulse the best health and economic results are obtained. It should, at least, be tried.

This will not be found to be a tedious operation after a little practice, when the habit of attention and care has been formed. On the contrary, a new appreciation and enjoyment of taste will be acquired, the delight of which has to be experienced to be understood.

Some hints on learning how to read the appetite, command the attention, and masticate and swallow food material properly follow.

Method. First; Last; And All The Time

Be sure that you are really hungry and are not pampering False Appetite. If true appetite that will relish plain bread alone is not present, wait for it. Especially beware of the early-morning habit-craving. Wait for an earned appetite, if you have to wait till noon. Then: "Chew," "Masticate," " Munch," "Bite," " Taste" everything you take in your mouth (except water, which has no taste), until it is not only thoroughly liquefied and made neutral or alkaline by saliva, but until the reduced substance all settles back in the (glosso-epiglottidean) folds at the back of the mouth and excites the Swallowing Impulse into a strong inclination to swallow. Then swallow what has collected and has excited the impulse, and continue to chew at the remainder, liquid though it be, until the last morsel disappears in response to the Swallowing Impulse. Never forcibly swallow anything that the instincts connected with the mouth show any disposition to reject. It is safer to get rid of it beforehand than to risk putting it into the stomach.

Sip and taste milk and all liquids that have taste as the wine-tasters do. They never drink wine and yet they get all the enjoyment there is in it and waste none. In a very short time sipping and tasting liquids and masticating and tasting solid food for " all they are worth " will become an agreeable and profitable fixed habit. Whether We "Eat to Live or Live to Eat," why not do as Above?
