are recorded in the inovements of the barometer, it necessarily follows that the 

 climate of different countries must vary as regards tirne very much after the mauner 

 of the climate of London, that is, it will he found to move in the cycles I have 

 mentioned. If we could only 90 back — but unfortunately there are no records — 

 to a curve similar to that which the barometer is forming now, we could foretell 

 the coming weather exactly. But as it is possible to calculate astronomically "when 

 the perihelion-curve, through which the earth is now passing, last recurred, we are fortu- 

 nately enabled to go back to the year which had weather identical with that of this year.

a is perihelion-curTe. — 6 is "barometric-curve. 

 c is mean pressure. 



« It is a matter for further investigation, but I believe that as the movement 

 of the earth about perihelion forecasts the yearly weather, so the monthly, weekly, 

 and daily disturbances in the movement of the earth may be found to forecast 

 monthly, weekly, and daily weather. I may bere remark that as the height of the 

 barometer every four years and every six years indicates generally what the height 

 will be in the succeeding four and six years respectively, so the barometer in one 

 set of six months indicates the barometer in the next set. I have already examined 

 this point for two or three years and have been astonished at the wonderful sym- 

 metry presented. 



« So that is we should never arrive at that perfection in forecasting which 

 I anticipate — to be able to teli with certainty what the weather next week will 

 be — we have it now in our power to know, when we sow our seed, whether we 

 shall have a good or bad harvest. The importance of such knowledge is inestimable».
