to the fubfcribers, that a Mr. Hornemann (another intended traveller) has begun his journey under very favourable circumftances. Having been provided with introductory letters to fome diftinguished literary characters in France, members of the Inftitut National, he proceeded to Paris, where he arrived in the beginning of July, and was received by thofe gentlemen with great kindness and attention; and with affurances, on their part, and on the parts of their colleagues, of an ardent zeal to promote the purposes of his miffion. M. la Lande furnished him with fome copies of his Mémoire de l'Afrique, and prefented him to a meeting of the Inftitut National, at which he was permitted to affift. M. Brouffonnet, who is appointed conful for Mogadore, introduced him to M. de Roche, lately nominated conful-general at Tangier; by whofe means he has formed an acquaintance with a Turkish gentleman, a native of Tripoli, now refiding in Paris; who being made acquainted with the motives and views of the African Affociation, has entered into Mr.

Hornemann's intrepid enterprize with a liberality and ardour particularly honourable to a Mahometan. Befides giving him much excellent advice and inftruction with refpect to his route, he has favoured him with a letter of introduction, written in Arabic, to a perfon of confequence refiding in Cairo, conceived in terms of the warmest recommendation. He particularly requests his friend "to introduce Mr. Hornemann to such Mahometan merchants (men of integrity) as have travelled into the interior of Africa; to furnish him with every affiftance and facility in profecuting his journey; and, above all, to fecure to him fuch protection in the caravan with which he may travel, as may render his progrefs not only free from peril, but commodious and pleasant.

Thus provided, Mr. Hornemann was on the point of proceeding to Marseilles; from whence to embark by the first opportunity for Alexandria; at which place it is probable he will arrive before the end of this month.
