 the system. The small tubes contract and expand ac' cording to the pressure of the blood.
 The vascular system Is closed cir culation system. The volume of blood remains constant The kidney secretes fluids as does the stomach, intestine, liver and the pancreas; the skin also secretes fluids We drink water ani tnvonntarily and automatically keep the total volume of circulating blood the same The blood pressure Is main tained by the pumping action of the heart and the elasticity of the ar teries The blood always fills the vascular system.
 Indeed the vascular system may be likened to a toy balloon filled with wa ter. When you squeeze it, it changes in shape, but the volume is always the same.
 There are a large number of people who experience difficulty in adapting themselves to existing conditions of life. We must all remember that man is part and parcel of the world. He may think himself the most important part. but actually, he is most de- pendent upon the outside world and the manifold forces around him.
 First, let us consider some of the forces of nature about us. The weight of the atmosphere in which we live is ever changing. A difference in the barometric pressure of half an inch is a tremendous force. If it becomes lighter, we have less pressure on our bodies, less pressure in our lungs, less oxygen held against us to breathe: we are, in fact, lighter. It is the same as if we suddenly went up into the air few hundred feet. Sometimes there is change in barometer reading from 29.5 to 3O.5 within short time. This is like going up high into the air above the earth. and then just as suddenly going down an equal distance below sea level Man involuntarily changes his inside workings and makes haste to adjust himself to these at. mospheric pressure changes. Rheu matics suffer pains, heart disease peo- pie have pain in the chest. and some people have digestive upsets.
 These sudden changes in atmos. pheric pressure are associated with winds and changes in temperature. In the Great Lakes basin region, we may go to work in a typical southern mild sunny morning and step out to lunch in northern Canada atmosphere. The air we breathe is the one physical force of Mother Nature that man has not changed in any way. The at mosphere is pulled and pushed over the earth's surface by physical forces that defy mans power to regulate.
 Industry has developed in the region of these storm paths. Civilization has advanced most rapidly where sudden changes in weather take place. As you and l make ourselves over and clean out the debris during these sud. den weather changes we emerge from the experience in much better cOndi tlon. We are stimulated and "peppeG up.' We feel like doing weeks work in one day. The highly strung, nerv. ous energetic person works like furnace under forced draft.
 Our circulatory system responds to ;hese weather changes. In many in, stances it is the first to show the strain. Attacks of spasm or uncon. trollable contractions of the muscle coats of these small arteries lead to various types of disturbed function
 The adult suffering from rheuma- tism, from heart disease, or from men, tai deformities are all examples of these maladjustments to atmospheric conditions.
 Scientists and engineers are now experimenting with indoor air condi tionlng. We hear of it being installed In trains, in hotels and theaters, in school rooms, in office buildings and factories, and in private homes. Sci ence has still 10 do great deal of re- search before we can determine how much benefit the patient with circu. atory abnormality can derive from living in place in which the tempera- ture and moisture can be regulated as nearly as possible to ideal conditions For him. Air conditioning Is an in. fant industry. The medical profes- sion waits its development with eager interest.
