INFLUENCE IN THE FEVERS OF INDIA, &C. 25 



The existence of a dimiial flux and lefliix in the 

 mercury of the barometer, is now sufficiently 

 estabhshed by the observations of Father Boudier,* 

 at Chandernagore ; of Mr. Trail, Mr. Farquhar, 

 and Colonel Peirce, at Calcutta; and those which 

 appear in my treatise, on the barometer, inserted 

 in the fourth volume of the Asiatic Researches; 

 and on the Coast of Coromajidel, by the observa- 

 tions of Doctor Roxburgh f. On the other side 

 of the globe, they have been observed in South 

 America'^, and the IFest Indies \\; and also at dif- 

 ferent places in Europe §. 



The proofs of a septenary flux and reflux, in tlie 

 mercury of the barometer, is confirmed by the ob- 

 servations of J\Ir. ToALDO, Father Cotte, and 

 others ; but still more pointedly by those lately 

 made in England by Mr. Howard, to be found in 

 a paper read before the Askesian Society in Loudon^ 

 and published in the seventh volume of the Philo- 

 sophical Magazine. 



Such is the support and security which the doc- 

 trine of sol-lunar influence in fevers derives from 

 evidence direct and analogical From the sublime 

 discoveries of Lavoisier respecting the composi- 

 tion of the atmosphere it receives protection of ano- 

 ther kind. In the present imperfect state of our 

 knowledge regarding the component parts of at-
