LITERARY AND SCIENTIFIC NOTICES.

AFRICAN EXPEDITION.-Intelligence has been received from our African Travellers by which we learn that Captain Clapperton early in December passed through Hio, (the Yariba of the Arabs,) reaching by the middle of the month, Jennah, a considerable town of that kingdom, after a very fatiguing journey, through thick woods, meeting with the most friendly reception from the natives, who possessed numerous horses, and were expert equestrians.

From Jennah to Katunga, the capital of Hio, is about 30 days journey distance, (perhaps from 250 to 300 miles,) and the Niger (Kowara) is thence only three days march, Captain C. and his servant, as well as Captain Houston, had suffered from the country fever; but were recovered, enjoying a healthier climate on their route from Jennah, which lay over the Kong mountains. By the last accounts received, they were half way to Katunga, in 8° 23′30′′, and the elevation above the sea estimated at 2500 feet. From a place called Engua, Captain C. writes that his fellow-traveller, Mr. Pearce, had died on the preceding day, the 27th of December; while Dr. Morison and his servant, both unable to proceed, had returned to Jennah, and fell victims to this fatal climate.

The other division of the Expedition had made its way to Dahomey, being received by the King and his captains in a most hospitable manner. Mr. Dickson had also experienced a seasoning fever; but on recovery, had a conference with his Majesty of Dahomey, and on the last day of the year left his Court with an escort of 50 armed men, and 100 bearers, under the command of a relation of the King, for a town called Shar, seventeen days journey towards the north, being situated to the south-west of Yaury. Mr. James had returned to the coast.

Mr. H. W. Dewhurst, Surgeon, has in the press a Dictionary of Anatomy and Physiology, to be published in Parts, purporting to contain a complete System of Practical Anatomy and Physiology; the work will form a guide to the student in the dissecting room, and be found useful to the medical practitioner.

RUSSIAN CANALS-The Russian Government has ordered the immediate construction, of Canals, to unite the following rivers. Viz. the Moskwa and the Volga; the Scheksna and the northen Dwina, it is intended by uniting these rivers by this means to make a direct communication between the ports of Archangel and St. Petersburgh, and so furnish a conveyance for indigenous productions, towards the Baltic. The rivers Meineu and the Weichsel are also to be joined across the kingdom of

Poland.

Dr. Barry, of Paris, has in a forward state, Experimental Researches on the influence of Atmospheric Pressure upon the Venous Circulation, Absorption, and the Prevention and Cure of lydrophobia, and the Symptoms arising from every species of Poisoned Wounds.

OMOGRAPHY.-The Invention of a new art by a M. Aiguebeile, of Paris, to which the name of Omography has been given, is talked of: it is said to afford an extraordinary facility in executing, not only all that has hitherto been done by engraving and lithography, but also the effects of the pencil and the stump, which neither the graver nor the crayon has yet been able to accomplish.

Mr. Curtis has in the press, a fourth edition of his Treatise on the Physiology and Diseases of the Ear, in which he has shewn what may be performed in Acoustic Surgery, particularly in cases of Deaf and Dumb.

There is announced, as preparing for publication, a Work by P. F.

In the course of the work, the village church and parsonage, will be introduced together with the schoolhouse. Occasional ideas will be added for ornamental root-houses, and seats to decorate the Pleasure Ground.

TO MATTHEW BUSH, of West Ham, in the County of Essex, Calico Printer, for his Invention of certain Improvements in Machinery, or Apparatus for Printing Calicoes and other Fabrics.

[Sealed 7th October, 1824.]

THE principal feature of novelty claimed under this patent is the employment of small rollers with engraved surfaces, for printing portions of the calico or other fabrics with any desired pattern, which the patentee denominates repeating rollers. The general construction of the machinery to which these rollers are adapted does not appear to be new, and is therefore only introduced to shew the manner in which the repeating rollers are to
