INFLUENCE IN THE FEVERS OF INDIA, Bzc. 27 



in the paroxysms of fevers ; remembering, at the 

 same tim.e, that those are occasionally subject to 

 certain perturbations of inferior consequence, from 

 the attractions of the planets. To conceive this, 

 is all that is required. 



3d/.i/. To render Q.ur knowledge of this principle 

 sufficiently perfect, by giving it all the advantages 

 o^ numerical precismi, without wiiicli no physical 

 principle can ever acquire the form and efficiency 

 of science, it is necessarj^ that all the various de- 

 grees of increase or decrease that sol-lunar influence 

 is liable to undergo at various hours of the day 

 and night, should be accurately ascertained, and 

 expressed in number s. 



It is to attain this end that I am now led to pro- 

 pose the scheme of an astronomical Epheriitris for 

 the purposes of medicine and meteorology, con- 

 taining a column for the horal "cariations of sol- 

 lunar power both day and night, ascertained and 

 expressed with all the precision that can be ob- 

 tained. 



The perturbing force of the moon being found 

 by De La Place to be three, and that of the sun 

 one; and four, therefore, being the wnole of the 

 perturbing power with which they can act upon 

 this globe, we shall obtain by dividing this sum 

 into forty parts or degrees, a scale sufficiently ex- 

 tensive and minute for expressing all the difierent 

 degrees that can possibly occur. 



By means of this Ephemeris, every phenomenon 

 that appears being instantly and easily compared 

 with the existing corresponding degree of sol-lunar 

 power, certain general truths will at length be ob- 

 tained, respecting its agency and interference in
