Such patients have digestive fermentations to torment them, resulting in flatulent distension which encroaches on the cavity of the chest, which in excessive cases may cause short and rapid breathing, irregular heart action, disturbed circulation in the brain, with vertigo and headache. An over-distended cæcum, or sigmoid flexure, from pressure, may produce dropsy, numbness or cramps in the right or left lower extremity. The reports of the _post-mortem_ examination of the colons of hundreds of subjects reveals a series of horrors more weird and ghastly than were ever penned by Eugene Sue, or Emile Zola. The mind shrinks in dismay at the appalling revelations, and shudders at the possibility of the “human form divine” becoming such a peripatetic charnel house. Is it any wonder that the average human system, being thus saturated with impurities, should succumb to the first exciting cause? Is it not, in fact, a greater marvel that the rate of mortality is not even higher than at present? My object in publishing this book is to point out the true cause of disease, together with the means for its prevention and cure, and that, too, by a simple and inexpensive method of hygienic treatment, which has proved eminently successful in tens of thousands of cases, which is perfectly harmless and natural in its action, and absolutely free from even the suspicion of a drug. PART III. RATIONAL HYGIENIC TREATMENT. Having striven to explain in an intelligible manner the true nature and cause of disease, and to point out the inadequacy of the drug system of treatment to combat pathological conditions successfully (not from any lack of intention on the part of the drug practitioners: but from the unreliability of their methods), I shall now proceed to lay before you the system of treatment which it is proposed to substitute in its stead, and I unhesitatingly affirm that it will be found so simple, so inexpensive and so obviously based on common sense and true hygienic principles, that the thoughtful reader cannot fail to give it his unqualified endorsement, and will be lost in wonder that any one should fail to adopt it, when made acquainted with its simplicity and its marvellous results.
