It is these same ions that play a primordial role in the excitation of the vago-sympathetic system, which, with its modifications, determines that physiological syndrome that permits the forecast.
THE SCIENTIFIC VALIDATION
To demonstrate how no instrument constructed by man possesses that sensitivity of nervous reactions, we are going to relate what Dr. Jules Regnault⁵ writes about a colleague of his, Dr. Raphaël Dubois who, going to visit a sick woman who complained of pains related to meteorological influences, verified that she had bought a barometer and that, when he returned to visit her, she had bought a second barometer; and then the sick woman told him:
"The first one was no good, but the second is no better than the first, since both lag considerably behind my pains."
CLIMATE
We know that, from the medical point of view, climate is constituted by all that set of conditions, whether of air or of soil, that are in relation to vegetable and animal life, such as geographical position, altitude above sea level, nature of the terrain, hygrometric state, temperature of the different seasons of the year, direction of winds, nature of vegetation, etc.
Now then, climate, whether temperate, tropical, subtropical, polar or arctic, mountain, etc., exercises an indisputable influence over living beings. Thus Prof. Galeotti⁶ describes for us the influence of climatic variations on individuals:
"The organism of man and animals is capable, but only within certain limits, of adapting to changes in external conditions. The acclimatization of Europeans in tropical countries does not result easy; and, although an individual may succeed in adapting, his children are born weak and often sterile, as has been frequently observed in the British Indies. In the same manner, animals or men transferred from warm climates to temperate or cold climates, weaken and remain exposed to many diseases, especially of infectious nature.
"Passing from a temperate climate to a warm climate, the nervous system remains, in the first times, very excited, then depressed; the functions of the digestive apparatus become very slow. The secretion of sweat is almost always abundant, while the elimination of urine diminishes; cardiac activity grows, the pulse becomes frequent, the number of respirations increases. Thus, the organism, impoverished of blood, poorly nourished, weak, is exposed, not only to common infections, but also to all the special diseases of climate. Less harmful result the excessively cold climates."
THE DEEPER IMPLICATIONS
This scientific investigation of meteorological influences reveals principles that extend far beyond weather forecasting. It demonstrates the intimate connection between cosmic forces and biological systems, validating traditional knowledge through modern observation.
