52 ON THE LUMINOSITY

 very apropos in that conjuncture, namely, that most were per- 

 suaded that Cortez had brought a very powerful army, which, 

 as appeared to them, occupied most of the plain. From the 

 windows of their retreat, they discovered, at different distances, 

 some lights, which, interrupting the obscurity of the night, 

 appeared to their eyes lighted matches and troops of mus- 

 queteers, being certain insects, gusanos, like our glow-worms,
