from the stomach and intestines. Also along the intestines there are little projections (villi), through which the food passes into a blood stream leading to the liver, where the blood is then purified. These projections also contain lacteals or little vessels containing blood without its red corpuscles. A duct carries this colourless blood mixed with absorbed food to the left side of the neck, where it empties into the blood stream. These lacteals have a special affinity for the fat of the food. Most of the rest of the food, including the proteid and the carbohydrate or starchy portion now in the form of sugar, passes into the capillaries, and then is led to the liver.
The liver will not let through more sugar than is required, storing it up for future use. It also acts as a careful guardian, by arresting many poisons which would otherwise pass into the general circulation. The liver requires for the proper performance of its functions plenty of pure blood, hence the necessity for fresh air and exercise, that the lungs may work well. The liver is easily influenced by alcoholic beverages, and by getting too hard work to do through eating rich foods. A consideration of this delicate and intricate process, whereby the digested food is absorbed, will show that badly-digested food can not hope to be well assimilated, consequently attention should be paid to the quantity and quality of the food we eat (see Digestion; Diet).

Whatever thus makes living substance is nourishment; whatever fails to do so is not. If food be taken, and even digested, without being thus assimilated, it becomes an injury to a patient instead of a help. In cases of fever, inflammatory disease, or wasting sores, much rich food feeds the fire. It is like laying rafters on the roof of a burning house for purposes of repair. In such a case small quantities of milk, or milk and hot water (see Digestion), represent the total food which can be effectively used in the body. We write on this subject that in treatment our friends may watch not to injure by making the blood too rich in elements which the system cannot usefully assimilate. Such foods as oatmeal jelly and wheaten porridge will often furnish more real nourishment than pounds of bread, beef, and potatoes. A little careful thought will guide to correct treatment in this matter. An easily assimilated diet is found in Saltcoats biscuits and hot water; many inveterate stomach troubles have yielded to this, when taken as sole diet for some weeks (see Biscuits and Water).
Treatment may also be given for lack of assimilative power. The back, especially on either side of the spine, is rubbed with gentle pressure and hot olive oil. This pressure is so applied that a genial heat arises along the whole spinal column. This done twice a day, for half-an-hour at a time, and continued for several weeks, will markedly restore assimilative power. Cases which have been perfectly helpless for eight and even ten years are cured by this simple method, sufficiently and carefully followed.
We had a patient who was stout, but weak and weary, with the muscles slack and showing loss of power. The effect of back-rubbing, accompanied by easily assimilated food in small quantities and often, was to lessen his weight by a considerable amount. But the muscular power at once began to increase, and the man was soon like one made anew. Digestion had not been impaired in this case, but the blood formed by it was not converted into good living substance. Sight and hearing have even been restored by these means when the failure in eye or ear has been due to waste material accumulating, as frequently is the case.
In connection with many troubles, what may be called local assimilation has to be considered. A foot, say, with a bad abscess or diseased bone (see Pain, Severe) is cured by hot bathing and pressure. From a shrunken and feeble limb, the leg grows to a healthy and strong one. This occurs because the heat and pressure have so stimulated its vitality that the material supplied by the blood can be utilised in the leg for purposes of healthy growth. So with any other part of the body. Such diet as we have indicated supplies easily assimilated substance. The local heating, pressure, and bathing enable this substance to be utilised where it is needed. A little careful thought on this line will guide to proper treatment of almost any case where assimilation has failed, either locally or generally, and will lead the way to a method of cure.
Asthma exists in various forms, having equally
