Jan. 20 - continued 
gases that trouble one and attack the chest until one can not breathe. 
These latter issue from the cracks formed by the slumping of the walls. 
These fissures are numerous about the circular crater. Sr. Ordonez, 
whose age prevented him ascending the crater xvas, however, able to reach 
the vicinity of the lava vents. 
21 - The noises in the crater continue; at moments they are stronger than 
the escape of steam from a boiler. In the afternoon a sunset of small, 
yellow pillars of vapor. At night one can notice a dimunition of the lava 
flow near its source but between the volcano and Canijuato the front is 
widening.

in the crater continue like heavy deep thunder, with simple vapors that 
throw the scoria toward the southwest. 
23 - The noises continue as heavy thunder, sometimes very deep. In the

For this same reason, it is not strange that the vents continue to open, in-

From 10 to 11 o’clock, rather strong noises with a quantity of bombs that 
fall on the south and .southwest flank of the cone. All the volutes of 
vapor pass toward the northwest. In the afternoon some bursts of vapor
