It is far better to remount the object, or select another. Indeed, for the finer work, it is advan- tageous that the objects should lie closely on the undersurface of the thin cover, and if, of the diatomaceous class, they should be dried on it before being placed on the drop of balsam warmed on the glass slide ; this may likewise be thin, and certainly sho^id not be thick. If there be any vibration from unsteadiness of the apparatus, or from wind, the operation of determining the best focus wUl prove very troublesome.
