A few years ago, says Mr. Hillenmeyer of Lexington, hardly a walnut tree in Fayette Co., Ky., but was full of Mistletoe. Today a cluster of this plant is quite rare. A careful examination last winter of nearly fifty acres of walnut woodland, failed to discover a single cluster. In 1877 many trees in this same tract were literally overgrown with this plant. Why has it disappeared?

Solidification of Oxygen was exhibited for the first time at the Royal Institution, a few days since, by Professor Dewar. The solidification is accomplished by allowing liquid oxygen to expand into a partial vacuum, when the enormous absorption of heat that follows results in the production of the solid substance. Oxygen in a solid condition resembles snow in appearance, and has a temperature of about 200 deg. Centigrade below the freezing point of water. - Gardeners' Magazine.
