THIS

of

HIS is an Exhibition of the Wonders of Nature by means MIGROSCOPES of extraordinary Magni tude, several of them being from six to eight feet in length, and from nine to sixteen inches in diameter. The whole of the apparatus has been contrived and constructed by PHILIP CARPENTER, Optician, No. 24, Regent-street, corner of Jermyn-street, London.

During the short time the Microcosm has been opened, it has given the greatest satisfaction and delight to its numerous visitants; and the various publications which have noticed it have given it their most decided approbation, as the following short extracts from a few of them will show :

"We have been so highly gratified by repeated sights of this truly magnificent collection of microscopes, and well-selected objects, that we cannot avoid earnestly recommending our readers to themselves of an early visit to it."-Gill's Techxical Repository.

"We have been highly gratified by a recent visit to this novel and interesting exhibition."-Literary Chronicle.

"On visiting this exhibition, we scarcely knew whether to adm re most the wonderful phenomena that presented themselves, or the skill and ing nuity by which the scientific inventor had made these apparent to the visual organs."-Atlas.

"Of all the instruments which astonish and instruct at one glance, that of the microscope is decidedly the most prominent. We were therefore particularly gratified the o her day, in strolling down Regent-street, by entering an exhibition. called the Microcosm,-in which all the known powers of that instrument are powerfully developed."-Watchman.

This Exhibition is now closed for a few weeks, for the purpose of rendering it still more worthy of the patronage of the scientific world and public in general, by the addition of an Achromatic Microscope, and a Reflecting one on the plan of Dr. Goring; various other improvements are likewise making. A separate room is also fitting up for exhibiting the SOLAR MICROSCOPE, on a grand scale, with Achromatic Object Lenses, which P. CARPENTER is now constructing for the purpose. During the hours in which the Sun is unfavourable for the Solar Microscope, a CAMERA OBSCURA, or LIVING PICTURE of Regent-street, will be exhibited in the same Room.

P. CARPENTER invites the attention of the Nobility, Gentry, and Public in general, to his Shop, No. 24, Regent-street, where he respectfully solicits their patronage and support. Having been nearly 30 years engaged in business as a practical Optician, he is able to supply TELESCOPES, MICROSCOPES, and every other article in the Optical way, superior to most, and inferior to none.

P. C. wishes particularly to recommend his

ARTIFICIAL TEETH with

out SPIRAL SPRINGS, TYING, &c. Mr. Prowett is now practising with certainty, a method of supplying the deficiencies of the Teeth by which the use of Spiral Springs, Clasps, Tying, or any of those mechanical means of fastening which are so injurious to the remaining Teeth, and so unpleasant to the wearer, are wholly avoided. This method accomplishes in a high degree the objects of the art in respect to mastication, utterance, and appearance, and renders the wearing of Artificial Teeth easy and convenient. It is equally applicable to cases now deemed difficult, and does not in any instance require extraction of teeth or any painful operation. A slight inspection, which is freely offered to all persons who take interest on this subject, particularly to the medical profession, will fully prove that the above statement is entirely and scrupu lously correct.
