Clouds and their Combinations. By Elijah Walton.—Mr. Walton is a

connoisseur in clouds. He has described and drawn some scores of combinations, from the " plain cloud," to the cloud which seems to pile its masses into the semblance of mountains or cathedrals, from the fleecy cirrhus to the cumuli displaying the most glorious effects of colour. Mr. Walton thinks artists should study clouds before they paint them, a rule neglected by too many landscape painters, and his analyses are intended to help them to the necessary knowledge. The work, though slight, seems carefully done, and the names for the different combinations are happy and expressive.
