On Some Specific Febrile Diseases of Malarious Origin, and on the Necessity of the Existence of Germs for Their Production

ion of blood tolerated. Albuminous urine the exception. Liver not affected. Spleen invariably affected. Suppression of urine the exception. Haemorrhages from stomach in bad cases the exception. Antagonistic power of quinine J)eyond the reach of question. Death seldom occurs before the seventh day. Remittent merges into intermittent. One attack affords no immunity from future ones. No immunity obtained by any length of residence. Convalescence protracted. Though a smell is observable in remittent fever, it is different and less pronounced than in yellow fever. irom the above sketch we may conclude: 1. 1 hat the various specific febrile diseases of malarious origin are possessed each of a distinct and separate individuality, and are dependent upon some principle, element, or germ which ?implanted within the system, and developing?marks each with characteristic pathognomonic symptoms. 2. That the germs producing these specific febrile diseases are many and diverse, each limited to a habitat, each exhibiting a special modus operandi producing its like, and in its following marked by a precise and determined conformity, never AND THEIR CAUSES. 109 undergoing transmutation, but persisting in a unity of action, and perpetuating its specific qualities to the end of time. 3. That epidemics are simply an intensified state, an aggravation of the natural conditions, arising either from a multiplication of germs, or from a greater degree of virulence of these germs.
