of the cycle, the first day of the year was the 

 8th, the 7th, and the 6th of January ; in every 

 year of the sign tochtli the Mexicans lost a day ; 

 and by the effect of this retrogradation, the year 

 colli of the fourth indiction began the 27th of De- 

 cember, and finished at the winter solstice, the 

 21st of December, not reckoning the five useless 

 or complementary days. Hence it results, that 

 the last of the nemontemi, called cohuatl, and 

 considered as the most unlucky day, because it 

 belonged to no period of thirteen days, fell, at the 

 end of the cycle, on the 26th of December ; and 

 the thirteen intercalary days brought back the 

 beginning of the year to the 9th of January. In 

 order to render what we have just explained more 

 clear, we shall here add the table of the last 

 twenty-five days of the first year of the cycle.
