In your last "Gossip," mention is made of a new process of painting on anatomized leaves. This is very beautiful work. For the benefit of your lady readers, I give the following, which I take from my note-book, where it was inserted some years ago: "Fill an earthen pot with rain-water; then put in leaves or seed-vessels, selected in a state sufficiently matured for the woody fibre to be completely formed, so as not to be flaccid; at the same time, it should not be too old and hardened. Let them remain in the water, without changing, until they become pulpy, and the outer skin and fleshy matter will brush off (with great care) with a common painter's brush. Should any part of the skin still remain firmly fixed, put them again into the water, and wait patiently. When perfectly clean, bleach them in chloride of lime. Magnolia leaves require about six weeks; pear, tulip, and mulberry-tree leaves, about three; ivy (very pretty veins) requires three months' maceration; orange and lemon leaves, six months." Yours, etc., S.
