Dynamic Theory

a hypothesis broached by Kant that all matter originated from the action of two mutually antagonistic forces-attraction and repulsion. All the predicates of these two forces are attributed by Kant to motion. As applied to heat, it is a theory or hypothesis that now is generally accepted as the correct one-which represents a heated body as being simply a body the particles of which are in a state of vibration. This vibratory movement increases as the body is still more heated, and diminishes proportionately as it more or less rapidly cools. It is called also the mechanical theory of heat.

Dysentery

a febrile, infectious tropical disease, not common in this country. It may be acute or chronic, or again complex, and is very intractable and highly dangerous. It is seated in the large intestine, the lower part of the bowel, but sometimes extends upward into the small intestine above the ileocæcal valve. Dysentery is accompanied by straining, and scanty mucous and bloody stools, containing little or no fæces. The most frequent complication is with the liver and disease of the kidney. There is feverishness throughout, dry skin, furred tongue, thirst, sleeplessness, quick pulse, despondency, y, etc., slow convalescence, rarely complete, leaving the patient frequently a complete wreck. Ipecacuanha is the chief remedy, especially in the acute cases. In the scorbutic form, the Bael fruit is the best remedy. Dysentery usually commences with griping diarrhea, and shooting or cutting pains. In favorable cases recovery may take place in from three to four weeks, but death sometimes occurs in 10 or 12 days, or the case may extend over months or years.

Dyspepsia

difficulty of digestion. The action of the stomach on the food is that usually designated as digestion, and it is the derangement of this process that is usually expressed by the term dyspepsia. The sub-acute and chronic forms of gastric irritation and inflammation are the most common forms of dyspepsia, and are often caused by too highly seasoned or too abundant food and stimulant drinks. Another class of dyspeptic diseases is connected with irritation of the mucous membrane of the duodenum, causing perversion of secretions and disorder of functions. A third class of dyspeptic diseases depends on the nerves connected with the digestive viscera. Hence arises an order of dyspeptic symptoms independent of any immediate affection of the stomach. The most common causes of dyspepsia are excesses of various kinds, especially in the quantity of food eaten. The quality must also be considered, while good cooking is also a preservative against dyspepsia. Linnæan genus of
