RANGE OF THE BAROMETER IN ECUADOR, appendix. 



de hauteur entre 8 et 10 heures du matin ; qu'il descend ensuite jusque vers 

 4 heures de I'apres-midi ; qu'il est a la hauteur minima entre 3 et 4 heures, 

 pour rem outer jusqu'a 11 heures du soir, sans arriver toutefois a la hauteur 

 a laquelle il etait a 9 heures du matin ; qu'il s'abaisse enfin jusqu'a 4 heures 

 du matin, sans toraber aussi bas qu' a 4 heures du soir ; qu'il recommence 

 alors son evolution. C'est la, du moins, ce qui a lieu generalement." 



The observations published in the Quito Bulletin do not always accord 

 with this statement. In some months, the means of the 2 p.m. observations 

 are higher instead of lower than the means of those at 6 a.m. and 10 p.m., 

 and it will be seen from the table at p. 000 -that the very highest reading of 

 the entire year is one at 2 p.m. The following observations, however, made 

 by myself at Machachi, so far as they go, follow the law as stated by 

 Boussingault.

The smallness of the differences in pressure in Ecuador, and the regu- 

 larity of the variations, render that country particularly suitable for carry- 

 ing out such experiments as it is still desirable to make with the baro- 

 meter ; and there is probably no other region on or near to the Equator 

 where observations can be made with such facility between the heights of 

 7000 to 16,000 feet.
