12 REMARKABLE EFFECTS OF SOL-LUNAR 



observe their course with attention in future, when 

 the laws that directs it are explained and under- 

 stood, and I have no doubt that any physician 

 who will carefully attend to the diurnal and noctur- 

 nal returns of the tides, and will constantly hold 

 before him the prevailing tendency of fevers to ap- 

 pear at the commencement, and during the period 

 of the springs ; and on the other hand their pre- 

 vailing tendency to subside and terminate at the 

 commencement and during the period ot" the neaps ; 

 together with the observations that have been made 

 respecting the propensity of the paroxysmal, and the 

 maturity of the critical disposition, will soon obtain 

 more infovination respecting the phenomena of fe- 

 vers ; and be ^ble to form more just and certain 

 judgments and pi; j:;ostics respecting every event, 

 than if he were to study the history of medicine, 

 as it is now written, for a thousand years. In 

 short there is no revolution or change in thf course 

 of fevers that may not be explained bv these gene- 

 ral principles, in a manner that is consistent with 

 the laws of the human constitution, and those of 

 the great system of revolving bodies, which unite 

 together in producing them. 



Before I conclude this article, I must also re- 

 commend to every practitioner who wishes to eman- 

 cipate himself from the beaten track, to attend 

 carefully to the appearance of the urine ; for I can 

 assure them., from the experience of many years 

 attentive observation, that there is to be observed, 

 in the fevers of India, a constant and regular fluc- 

 tuation in the colour and consistence of the urine 

 in fevers. That is to say, regular diurnal and sep- 

 tenary changes in its character, coincident and 

 correspondent with the exacerbations and remis- 

 sions of sol-lunar influence.
