than etiologists have hitherto believed, and that clinicians 

 will have, consequently, to alter their diagnosis and adapt 

 their treatment accordingly. 



Zymosis, or bacterial proliferation, may be confined to 

 the cerebro- spinal fluid, and may begin and end there, but 

 often it is attended by bacterial attack of its containing 

 vasculature and organic environment, when meningeo- 

 neurilemmar complications arise, or by neuronal implication, 

 when diseases of the proper nerve elements develop the 

 symptoms proper to disordered nerve substance and func- 

 tion, as may be witnessed in such diseases as tetanus, 

 hydrophobia, trypanosomiasis, "rheumatism of the brain," 

 " general paralysis of the insane," and many other familiar 

 central nervine affections. In such of these diseases, where 

 the neurons are attacked by the individual, or specific 

 bacteria belonging to a particular disease, the characteristic 

 symptoms of the particular disease then become manifest, 

 as its bacterial organisms grow and propagate themselves 

 according to their individual manner, whether they be 

 benign or malign and in such cases they are generally the 

 latter through the textures attacked being of such a 

 highly essential character, both in material and function, in 

 the economy of life and cerebration. In the neurono- 

 phagic processes indulged in by the individual bacterial 

 genus a manner of procedure and histological effect are 

 developed whereby, in many cases, the microscope can 

 distinguish the culprit and indicate the disease for the pro- 

 duction of which it is, by its specific action, pathologically 

 responsible. Thus, it becomes abundantly evident that a 

 wide field for the bacteriologist and clinician is here coming 

 into view, the exploration of which must yield abundant 

 information, both of a scientific, and practical, kind, for the 

 guidance of the future practitioner of medicine and the 

 satisfaction of the amour propre of pure science. 



The cerebro-spinal fluid thus becomes an incubative 

 medium and organic vehicular element of the greatest 

 moment to the scientist and clinician alike, inasmuch as it 

 possesses attributes the appraisement of which will require 

 the exercise both of their intelligence and the therapeutic 

 use of their united deductive and practical efforts. More- 

 over, according to that appraisement and practical use must
