SEEDY OR SPECKY.
Caused by want of thoroughness in cleaning and dusting a surface preparatory to varnishing. Likewise by the skinning over of a varnish, the broken particles of the skin then working into the liquid and thence conveyed to the surface. Also by using an unripe varnish, or a chilled varnish, or by varnishing on a cold, damp day in a room not properly heated.
The "lousy" or dirty varnish brush begets the seedy, specky work. It is a fruitful cause of such work, in fact.
