The table on page 39 shows the results of the meteorological ob- 

 servations taken in the principal cities of Mexico during the year 1896. 



Professor Mariano Barcena, director of our National Meteorological 

 Observatory or Weather Bureau, furnished me the following data about 

 the maximum and minimum of temperature and greatest oscillation 

 both in summer and winter of several cities in Mexico, located both at 

 the sea-level like Merida and Mazatlan, at different altitudes like Jalapa, 

 San Luis Potosi, Oaxaca, and at the highest level like the cities of 

 Mexico, Pachuca, and Zacatecas, showing the mildness of the Mexi- 

 can climate.
