IXFLUEXCE IX THE FEVERS OF INDIA, 6:C. 7 



Fevers in which the paroxysms do not succeed 

 each other in twelve hours (and which have been 

 hitherto denominated intermitting fevers when the 

 remissions were complete, ar,d remitting fevers 

 when they were not) all bciong to the class of im- 

 perfect types. 



For the purpose of illustrating these explanations 

 respecting types, 1 have constructed Table I. 



3^. Of the Durations and Crises of Fevers. 



Of the duratiotis and crises of Fevers of a Perfect 



Type. 



Febrile paroxysms shew themselves more fre- 

 quently during the period of the spring tides than 

 at any other time, and as these advance become 

 more violent and obstinate ; and on the other hand, 

 tend no less invariably to subside and terminate 

 during the neaps. 



By the concurrence of the remarkable and sud- 

 den remmion in the power of sol-lunar influence at 

 the commencement of the neaps with critical dis- 

 positions in a state oj peifect maturity^ all the diife- 

 rent perfect types, produced in the manner I have 

 explained, are brought to a final termination or 

 perfect crms ; and are thus limited to fevers of 

 different durations. 



The operation of this law is explained in Table 

 II, which exhibiting examples of the different du- 

 rations of perfect types, with the manner in which 

 they are formed, unfolds at one glance, the dark 

 and once impenetrable secret of crisis ; and ac- 

 counts for all the diversities that may appear in 

 their duration at different times.
