An atomizer nozzle is a kind of nozzle for producing a fine spray of a liquid based on the Venturi effect. When a gas is blown through a constriction it speeds up; this reduces the pressure at the narrowest point. The reduced pressure sucks up a liquid through a narrow tube into the flow, where it boils in the low pressure, and forms thousands of small droplets.Atomizer nozzles are used for spraying perfumes, for painting and in carburetors as well as water nozzles.

From the well known nocturnal habits of moths, and the certainty of their being destroyed by a light, a cheap and effective mode of destroying them, shown in the annexed figure. It consists of a pan of viscid matter placed upon a stake, which is set in the field of cotton at suitable distances. A block of wood is placed in the center of the pan, upon which is placed a lighted glass lantern. The moths, being attracted by the light, dash against it and fall into the pan, and are thus destroyed before depositing their eggs upon the tender leaves of the growing plant.

"It is not unusual to fine a decayed spot in the center of potatoes otherwise apparently in good condition. A microscopic examination a portion of the diseased part will show that the decay commenced where the vascular bundles concentrate. At that point the air is in greater volume than elsewhere. Although these mineral acids and caustic alkalies dissolve starch granuals, they do not affect the cellulose cells which contain the starch. When such spots are exposed to the atmosphere the fungus blue-mold forms on the surface. This disease, therefore, has not relation to potato-rot, as ordinarily understood. f represents the mycelium (roots) of blue-mold, Penicillium glaucum, and G that of potato-rot, Peronospora infestans." -Watts, 1874
