was repeated as introductory to that of shadows. The projection of shadows by a torch or candle and by the sun, was exemplified, and shadows were proved to be subject to the same rules of perspective as all other objects: and the lecture concluded with reflection in water, in which it was proved, that the reflection will always be equal to the apparent magnitude of the original object.

Mr. DAVY's tenth lecture on the chemical phenomena of nature related to the atmosphere. Its composition was pointed out; its constituent parts exhibited; water, carbonic acid, oxygene, and nitrogene. Mr. Davy stated the proportion of carbonic acid at about r, the oxygene as and the nitrogene as; these quantities he considered as the same in all parts of the air exposed to the influence of winds in cities, in towns, in mountains, and in valleys, on great continents, and upon the ocean. He attributed the superior salubrity of the air in the country as compared with that of

towns, to its being free from noxious effluvia.

British Gallery.

No. 100. The foot-path bridge.

R. Westall.

THIS is a delightful little bit of rural scenery, and executed in a very natural style. The old woman seated at the foot of the bridge, conversing with a young female peasant, adds an interest to the composition. The scene exhibits one of those deep, sequestered, solitary spots, alike fitted for the musing of the poet, and the haunt of the fairy.

Purchased by the Earl of Carlisle.

No. 106. Cupid.

J. Pocock.

ALTHOUGH this picture has not yet found a purchaser, it has great claims to original merit. Cupid is represented as a very beautiful boy, of about 12 years of age, sporting with a snake, which, by his presence, seems disarmed of its terrors.

A brilliant butterfly is perched upon his bow; and the arch little god is amusing himself with the animals before him. The expression is excellent; but the colouring, in the naked parts of the boy, is perhaps rather too raw.

No. 115. Cottage child.

J. Pocock. A PLEASING natural composition, and executed with great neatness and delicacy of colouring. The child is sitting down very contentedly to the enjoyment of some milk, which it drinks out of a pan. The legs and feet are well conceived and executed.

Purchased by Lord Boringdon.

MINIATURES.

No. 133. Saint and angel, (enamel, from Carravagio.)

> H. Bone.

It seems impossible for the art of enamel painting to go beyond the force and richness of colouring displayed in this picture: and yet there is an hardness

of outline which belongs, perhaps, rather to the original than the copy.

No. 159. Beatrice.

A. Chalon.

THIS is a whimsical composition enough. The head and hands of Beatrice only appear rising above a bush of rose trees; the colouring is rather too dry.

No. 140. Flowers.

J. Hewlett.›

Jr Mr. Hewlett continues to paint in this style, England will never have to envy Holland her De Heem and Van Hysum. It is, in truth, a wonderfully executed picture; there is a spirit and richness in the touch, accompanied at the same time, with great warmth and mellowness of effect, which are absolutely enchanting, and bring nature before the eye. When time shall have somewhat softened the brilliancy of the present varnish, these roses, and hyacinths, and lilies, may vie with the most successful similar productions of foreign masters.

Purchased by the Marquis of Stafford.

No. 147. Boy, after Sir J. Reynolds.

H. Bone.

THE original, of which there is a mezzotint engraving, is a very pleasing picture; and Mr. Bone has, in this beautiful effort of his pencil, shewn himself master of all those powers of touch and colouring, which have rendered Sir Joshua's picture so popular.

No. 148. The past, the present, and the coming hour. J. Shelley. THIS elegant composition consists of three females, of whom the retiring one represents the past hour, the central one the present, and the approaching one the coming hour. The air of gaiety, in the present and coming hour, is happily conceived and executed.

Purchased by J. A. Wright, Esq. M. P.

No. 149. Cynthia.

W. Wood.

MR. WOOD has, in this picture, painted a very beautiful countenance of some young lady, encircled by clouds. The head only appears: but this has
