210 A TREATISE 



The Inference. 



XII, 



From the preceding statement or the coincidences 

 observed in these four portions of the day, it appears 

 that we may reasonably infer the following proposi- 

 tions, limited to Calcutta in the month of April 1794. 

 1 st, That, in the interval between ten at night 

 and six in the morning, there existed a prevailing 

 tendency in the Mercury to fall. 

 2d, That, in the interval between six and ten in 

 the morning, there existed a prevailing tendency in 

 the Mercury to rise, 

 3d, That, in the interval between ten in the 

 morning and six in the evening, there existed a 

 prevailing tendency in the Mercury to fa 

 qtli, That, in the interval between six and ten 

 in the evening, there existed a prevailing tendency 

 in the Mercury to rise. 

 These different prevailing tendencies to rise and 

 fall periodically at certain times of the day and night, 

 necessarily imply a proportionate corresponding cause 

 sufficient to produce them. . But here we stop, and 

 venture to proceed no farther than to say, with Mr. 

 Farquhar, that they seem to be connected with the 

 diurnal revolutions of the planet which we- inhabit.

By an attentive examination of the Synopsis, it will 

 appear that the general characters of the tendencies 

 which prevail at the different periods we have de- 

 scribed, are liable, within their respective limits, to 

 several remarkable variations^ Viz.
