THE UNEXPECTED ACID TEST.
While wandering along the banks of the Shawsheen River in Andover, Mass., one pleasant spring day I found a speci- men of Carabus vinctus Web. under a piece of board. I at one pounced upon it as a prize, for at that time I had taken but few of them, and brought it closer to my face for another gloating look. As I did so I experienced the sensation that might have been caused by half a dozen red-hot needles striking my face, and at once lost all interest in the beetle until I had wiped my face with alcohol and stopped the painful smarting. I then investigated and came to the conclusion that the pressure of my thumb and finger had caused the apices of the elytra to impinge one against the other and, acting like a released spring, threw the acid secretion from the beetle into the air eight inches or more. I was greatly surprised at the strength of this acid and would fear rather severe results if it should enter the eyes. C. A. FROST.
