landscapes, this being the walk in which Mr. Glover excels. A few of this number are done by Mr. William Glover, and Mr. E. Price; two by Wilson, and two also by Claude Lorrain. The rest are the efforts of the genius of Glover, and were he never to paint another picture, he has done enough to insure him a niche in that temple to which every artist ought to aspire.

To the lovers of nature, and of landscape, we know not in the whole round of metropolitan exhibition, at the present moment, a more delightful treat than these paintings afford. Many of them have, it is true, appeared in former exhibitions at the Royal academy, but though old acquaintances they lose nothing of their first effect by a farther intimacy; on the contrary they will bear study. ing well. Although landscape is the chief, it is not the only attraction here. The Lions at Exeter Change; the Crown Pigeon from the East Indies: the Family of Monkies; the King Duck from Melville Island, North Pole, and a few others, which we cannot enumerate, are deserving attention.

But we cannot avoid directing the notice of our readers to a few of the landscapes. With ULSWATER and PATTERDALE, Mr. Glover is absolutely enamoured.

He has given us six different views of Ulswater and its neighbourhood, and three of Patterdale. Of these, No. 42, Ulswater from the Mountains above Gobray Park, and 62, Ulswater, strike us as the best; but each has its peculiar attractions.

No. 60, Mill at Vallombrosa, Italy; the views of Tivoli, No. 68, and 75; the Campo Vaccino, Rome.-the Temples of Concord, Jupiter Tonans, &c. at Rome, No. 71, will, among others of similar character, be contemplated with considerale satisfaction.

Wirksworth near Matlock, Derbyshire.---Morning, No. 59, is a well executed work; the cattle more especially demand our commendation. No. 44, the Junction of the Rivers Conway and Machno, North Wales, is one of those mountain scenes which never can be contemplated without delight. No. 25, Interior of Tintern Abbey, near Chepstow, Monmouthshire, has been, we believe, painted before by other hands; we think never better.

Loch Katrine and Benn Venue, Scotland, No. 35, have been consecrated by the muse of Sir Walter Scott. Mr. Glover has certainly done his part to convey the scenes to those who have not the opportunity of a personal inspection of the classic spot.

But we cannot proceed farther in our enumeration. Before, however, we take our leave of Mr. Glover's paintings, we would not have our readers to conclude that we consider them, in the mass, as faultless; we certainly do not.

There is an indistinctness of outline, particularly in the back ground of some of them, which we should be happy to see avoided. This artist seems peculiarly fond of the spray of water, and of mists and clouds; these are all, of course appropriate when introduced upon suitable occasions; but, in our judgment, they are sometimes introduced unnecessarily, and tend occasionally to injure the effect of an, otherwise, excellent picture. The light too is not always exactly as we could wish to see it. We are, notwithstanding, highly gratified to witness the collected efforts of this meritorious individual, and most cordially advise him to persevere.

DR. HUFELAND has published a little pamphlet at Berlin, shewing the geat inconvenience from the circumstance of different nations having adopted in their respective pharmacopoeias different denominations for the same article or preparation in the materia medica. Prussia, France, Russia, England, Austria, &c. possess each their pharmaceutical nomenclature, and a druggist residing in a large capital where foreigners resort in great numbers, is obliged, if he would understand every prescription which is sent to him, to collect all the pharmacopoeias of those nations, in order that he may consult them when occasion may require. This is a great evil; and it is extraordinary that, with the increased and superior knowledge of chemistry, and indeed every branch of knowledge allied to medicine, that the physicians of Europe can suffer such discrepancies to exist. Even in the British Empire we have three pharmacopoeias, the London, the Edinburgh, and the Dublin, between which considerable difference in the names and compounds still exists. Calomel for example is called in the Austrian Pharmacopœia Murias Hydrargyri mitis--in the Russian Murias Hydrargyri Oxydulatus Preparatus-in the Edinburgh and London sub murias Hydrargyri—in the French Murias Hydrargyri Dlucis, or Protochloruretum Hydrargyri. The rage for new names is not less injurious to science now, than the pertinacity with which old and unmeaning ones were formerly retained. A committee of the medicochemical savans of Europe might surely obviate these inconveniences.

Quadrature of the Circle.

53

M. Scamarella, a Venetian Geometrician, announces that he has solved the problem of the quadrature of the circle, and that he is ready to demonstrate it incontrovertibly to all the mathematicians in the world. According to M. Scamarella, the superfices of a circle is equal to three-fourths of the same diameter. It is also equal to the square of the circumference multiplied by half the radius, estimating their ratio as 7 to 21 and not 7 to 22, as Archimedes taught.

Conducting Power of Tin-plate.

AT a late meeting of the Helvetic Society of Natural Sciences at Bále, M. Pictet gave a detailed report of a remarkable descent of lightning upon a house at Geneva, which had no conducting apparatus: but the roof of which was covered with tin plates, and provided with gutters and pipes of the same metal in communication with the earth. The event proved the great importance and preservative property of the metallic covering used in the construction of the houses at Geneva. It is without doubt to this circumstance that can be specially attributed, the rarity of accidents which are produced by lightning in that city.
