cirrus

This cloud may either evaporate or disappear, or it may pass to the cirrus, or sink lower and become a cirro-stratus.

The Cirrus occurs in very great variety, and in some states of the air is constantly changing.

In dry weather the cirrus is sharp, defined, and fibrous in texture, the lines vanishing off in fine points.

Filling the vision to the south-west was Aurora Peak, in crisp silhouette against a glorious radiant of cirrus cloud.
