8 REMARKABLE EFFECTS OF SOL-LUNAR 



An application of these principles enables iis to 

 explain in a similar and consistent manner the 

 formation of crises that have been called hnperfect. 

 It is obvious that whenever the remission in rhe 

 power of sol-lunar influence at the commencement 

 of the nepps acting equally on all, produces in 

 some c'dses perfect crises, and in others crises that 

 are imperfect, that the latter must be referred to 

 the immature and unprepared state of the critical 

 disposition to concur completely in that e\cnt. 

 And although perfect crises, owing to the cause 

 which I now mention, do not always take place at 

 such junctuies, yet no fextr, as far as my experi- 

 ence goes, ever passes the comn>encen".ent of the 

 neaps without some evident abatenent or remis- 

 sion in the degree of ics violence; or without ex- 

 hibiting some evident approaches towards a solu- 

 tion or crisis; and they are approaches such as 

 these, in which the critical disposition concurs 

 only partially and incompletely with the remission 

 of sol-lunar power, that constitu'^e those changes 

 in the state of fevers that have been hitherto deno- 

 minated imperject crises. 



This explanation respecting the nature of imper- 

 fect crisis being premised, I have now to observe, 

 that although Table II, exhibits only such forms of 

 perfect types as terminate by a linal and perfect 

 crisis on the commencement of the neaps, it will 

 now be well understood, that all fevers do not 

 terminate finally and completely at this jimctiue; 

 but that in many cases; tlie crises being imperfect^ ■ 

 the paroxysms continue to return for some time in 

 a more moderate degree:, and generally postponing 

 with the periods of the tides, subside, and at last 

 disappear gradually and imperceptibly. The ini- 

 perject crises of perfect types, such as these which 

 I have last described, being less distinctly marked
