The ' Diariode los nuevos Descu- 

 brimientos de todas las Ciencias 

 fisicas,' volume ill. pages 56, 200,

 resting meteorologicalobservations, 



" The following is a table of the 

 variations of the pressure of the air 

 in the nine first months of the year 

 1793— 



" The mean height of the baro- 

 meter at Madrid, observed by Don 

 Felipe Bauza, shows that capital 

 to be elevated three hundred and 

 nine fathoms three-fifths above the 

 level of the ocean, according to 

 M. de Laplace and the new co-er- 

 ficient of M. llamond, allowing 

 the barometer on the coasts, with 

 Shuckburghand Fleurieu Bellevue, 

 to be at three hundred and thirty- 

 eight and twenty-four lines. Ma- 

 drid consequently stands as high 

 as the town of Inspruck, 

 which is situated in one of the 

 very high defiles of the Tyrol. 

 The elevation of Madrid is fifteen 

 times greater than that of Paris, 

 three times greater than that of 

 Mount Valerian, and also three 

 limes greater than that of Geneva. 



" Lalande was the first who 

 made known the elevation of Ma- 



drid, according to the observations 

 which were communicated to him 

 by the celebrated geometrician, 

 Don George Juan ("Memoiresde 

 I'Academie des Sciences de Paris," 

 for the year 1776, page 148.) 

 He says, that in the street of los 

 Presiados, near the portijo de San 

 Martin, the town is two hundred 

 and ninety-four fathoms higher 

 than Paris ; which makes it three 

 hundred and fourteen fathoms 

 above the level of the ocean. Ac- 

 cording to M. Thalacker, the mi- 

 neralogist, who has taken several 

 heights with the barometer in the 

 environs of Madrid, the king's pa- 

 lace at St. Ildefonso is five hundred 

 and ninety-three fathoms, which is 

 higher than the edge of the crater 

 of Mount Vesuvius. No other 

 monarch in Europe is possessed of 

 a palace in the regions of the
