Mississippi.--No original books of special interest have been published during the month. In our department of Literary Notices mention is made of those which are of most importance.--Mr. PRESCOTT, the historian, is traveling in Europe. He is announced as having been present at a recent meeting of the London Archaeological Society.--Mr. H. N. HUDSON, whose lectures on SHAKSPEARE have made him widely and favorably known as a critic, has been engaged by a Boston publishing house to edit a new edition of the works of the great Dramatist, which will be published during the coming year. Mr. Hudson's ability and familiarity with the subject will enable him to make a very valuable and interesting work.--GARIBALDI, who achieved distinction in the defense of Rome against the French, is coming to New York, where he was to be honored with a public reception from the authorities.--The capture of Stoney Point was celebrated this year at that place, for the first time. HUGH MAXWELL, Esq., of New York, delivered the address. The celebration is hereafter to be annual.--In no department of mechanism is the progress of the age more conspicuous than in printing presses, as is shown by the fact that Messrs. Hoe and Co., of New York, are now constructing a press which will work from 15,000 to 20,000 per hour. It will be thirty-three feet long, with eight printing cylinders, and will cost about $21,000.--A newly invented locomotive engine, intended for use in the streets of cities, has just been put upon the Hudson River Railroad at its termination in New York. It consumes its own smoke, and is entirely inclosed from public view--presenting the appearance of a simple baggage-car. The engine is of ninety horse power. * * * * * News from LIBERIA has been received announcing that the government has at last been able to effect the purchase of the Gallinas territories, including the whole from Cape Mount to Shebar, except a small strip of five miles of coast which will soon fall into their hands. The chief importance of this purchase springs from the fact that Gallinas has been for many years the head quarters of the slave-trade--an enormous number of slaves having been shipped from there every year. The government paid $9500 for the territory, and further agreed to appoint commissioners to settle the wars in the country, and open trade with the interior tribes, as well as to settle among them and instruct them in the arts of civilized life. This may prove to be an important step not only toward the suppression of the horrible traffic in slaves, which the united efforts of England, France, and the United States have hither to been unable to effect, but also toward the civilization of Africa, a result to which no philanthropic mind can be indifferent. * * * * *
