MM. Fremy and Cloez have extracted and isolated the blue coloring matter of flowers - a highly delicate operation. It is not indigo, as was supposed; they call it cyanine. It is turned red by acid vegetable juices, and they find it in certain roses, peonies, and dahlias. Viale and Latini, of the University of Rome, have, as they believe, confirmed the supposition that the odor of plants and flowers was due to ammonia; the odor being good or bad according to the proportions in which the ammonia was combined. From this it is shown that plants are doubly beneficial, by absorbing ammonia, as well as exhaling oxygen. We must'remark, however, that some chemists dispute the accuracy of these conclusions.

Sundry Matters promised for this month have been crowded out unexpectedly, among them communications from valued correspondents on subjects of permanent interest from Cincinnati, New Jersey, Ac, but for which room will be found in our next. The delay in publishing the report of the Pennsylvania Horticultural Society, was unavoidable. Interesting matter for the Horticulturist is now crowding in upon us.

The "Calendar of Operations" which we commence, it is intended to carry through the year, forming a feature that many have regretted the absence of in former volumes. It will make the present a valuable book of reference for the future, as well as the present time, and is by an able hand.

The Poultry Exhibition in Philadelphia, a few weeks since, was very successful and useful. The Governor of the State attended and made a very good speech.

Is Grape Culture and Waine Making firmly established among us? - This question we put to a distinguished vine-grower in Cincinnati, R. Buchanan, Esq., more to satisfy some friends than to clear up any doubt of our own. The following is his reply: "I am happy to be able to say that, in the West at least, I consider the vineyard culture of the Grape firmly established. It is also increasing with great rapidity all over the West and Southwest. The sale of grape-cuttings in Cincinnati last spring amounted to over 2,000,000, and of stocks 300,000. I sold from my own vineyard 140,000 cuttings. This looks like progress. The demand for the wine fully equals the supply, but the hard times of last year caused an accumulation of the stock of sparkling Catawba (the most expensive of our wines), which will take another year to diminish. I repeat to you in all candor my opinion, that the vine culture is now established as a branch of national agriculture that cannot retrograde. It has also the sympathy of the moral part of the community, who believe that the spread of the wine will diminish intemperance".

The Niles Pear, exhibited at the December meeting of our Horticultural Society, is a foreign variety with a native name, and was thought by many to be identical with the Easter Beurre, but comparison from the same place of growth, showed how distinct they are. The Niles was then nearly ripe. There was a fine display of Passe Colmar, which is to December what the Seckle is to the September month, scarcely to be excelled in its season. The Vicar of Winkfield looked "watery" beside the Duchesse D'Angouleme.
