Swell Cans.

Dr. J. G. Johnson contributes an article to the Sanitarium, upon poisoned canned goods. He says: “If a can is sound the head is sunk in. If the contents have commenced to decompose the head is bulged out Dishonest dealers buy these ‘ swells,’ as they are called, punch a hole in the heads, and put the cans in boiling wax to drive out the gases, after which they solder up the hole; that is to say, they repeat the process followed in canning. But cans so treated will have two solder holes instead of one. Buch cans, if purchased, should at once be sent to the Board of Health, along with the contents and the name of the grocer who sold them.”
