INFLUENCE IN THE FEVERS OF INDIA, &C. 5 



inon, it IS well established by expeiience, that the 

 fever being once commenced, tlie paroxysms are 

 very rarely disposed to cease in less than four days, 

 and seldom so soon ; and are not in general in- 

 clined to continue more than twenty-one. 



Th.e laws that regulate the progress and matura- 

 tion of the critical disposition, in that constitution 

 which prevails in remitting and intermitting fevers, 

 which are generally attended with large secretions 

 of bile, and are the endemic fe\'ers of warm cli- 

 mates, have not been as yet ascertained by any- 

 precise rules respecting their duration. Rut it ap* 

 pears to me that, whenever there are free dis- 

 charges of bile, there is always a greater tendency 

 towards a crisis or solution of the fe^'er, than when 

 there appears but little or none, which is gene- 

 rally the case during the height of the typhus ; and 

 until some approach towards a crisis either perfect 

 or imperPect has taken place : and .the peculiar pa- 

 roxysmal, as well as the critical disposition in the 

 typhus, and in remitting and intermitting fevers, 

 giving occasion to forms of different type and du- 

 ration, may perhaps be connected v/ith different 

 states of tlie liver peculiar to each.

 those positions of the sun and moon that regulate 

 the rising and falling of the tides.
