There is a critical period, if the treatment is persevered in: it is when Nature is about to resume her power over the disease, the latter having been attacked, and seeking to escape. It may be compared to a tiger which a man is tempting in his lair: for a time, it lies dormant, occasionally giving signs of existence, when suddenly the animal rouses, and a violent struggle ensues. The man however proves the strongest of the two. In all future attacks too, which are less vigorous, the tiger is defeated, until he finally quits his lair, and flies from his human conqueror. Thus at last are old diseases eradicated. In acute cases, the first rencontre often settles the affair. Under the Water-cure it frequently happens that every evil and pain is increased in intensity from the fact of the strength being always progressing. The weak and debilitated feel little pain; feebleness has produced insensibility. As the vital force diminishes, in the same proportion are the symptoms less violent; but when strength and vigour are daily gaining ground, so do the symptoms become more vigorous and intense. Nature is in a state of revolution; and, by being reinstated in her rights, she has declared war with all foreign powers that ventured to invest her citadel, and trample upon her rights and laws during the period of her prostration. An officer in the Prussian army, author of the most concise and best-written work on the Water-cure, told me that at Gräfenberg six years ago he was radically cured of a complication of diseases: that he had the so-called crisis; the first attack was painful and distressing in the extreme; rheumatism returned to each part where he had previously felt it; his foot, which some years before had been trodden upon by a horse, became exceedingly painful; his hands and feet swelled to double their ordinary size, and there was a discharge of an offensive nature from them. This lasted for about ten days. In the course of his cure he had two other attacks, each inferior in intensity to the preceding one. After the last, he found his hearing, of which he had been deprived two years, restored; he could walk as well as ever he did, a necessary pleasure of which rheumatism had deprived him; in fact, he left Gräfenberg a new man, and has ever since been perfectly well. This gentleman said that, whilst in a fortress, with his regiment, almost all the officers, except himself, suffered from influenza, whilst he escaped, from drinking cold water and taking several ablutions a day. When a crisis is expected, Priessnitz increases the treatment, as he also does when it has made its appearance: instead of discouraging the crisis to proceed, he encourages it by all the means in his power. So that eruptions, boils, fever, diarrhœa, inflammation, or aught else brought out by the treatment, may be gradually reduced by it. In this stage of the Water-cure, no compromise can be made; the fight must be continued until the enemy quits the field.
