50 REMARKABLE EFFECTS OF SOL-LUNAR 



The cause, however, that produces tliese re- 

 markable ettects, and determines the paroxysms of 

 fevers to appear in (hfferent cases in various order 

 and succession, constituting fevers of diiftrent 

 types ; and that again whicii determines different 

 types to come to an end after certain intervals of 

 time, forming these into fevers of different dura- 

 tions, are questions which have hitherto defied the 

 research of physicians ; and cannot be explained, 

 except by the laws of sol-lunar influence. 



TABLE I. 



Explains the Types cf Fevers. 



The different types that occur in fevers are form- 

 ed by febrile paroxysms continuing to return in 

 succession for a certain number of days, at an in- 

 terval of twelve, twenty-four, and forty-eight 

 houis ; or some other larger multiple of twelve 

 hours ; and almost invariably in coincidence with 

 the period of the tides. The types of fevers, there- 

 fore, are formed by the action of sol-lunar influ- 

 ence producing paroxysms in coincidence with the 

 periods of the tides, at the intervals I have describ- 

 ed:, and difiier from each other, only in so far as 

 their paroxysms return in succession at intervals 

 formed by different multiples of twelve hours. 



To convey a general idea of this discovery, I 

 have constructed Table I, observing that it applies 

 to explain all the types that I have ever met with 

 in India; and agrees perfectly with the types that 

 are described by other authors. The first of these 

 examjjles, fiom the perfect coincidence of its pa- 

 roxysms with the pej.iod of the tides, I have 

 called 2i perfect type ; and all the others, from their 

 imperfect coincidence with those periods, iniper-
