Rh contained in the present number, is £3 12s., or without the rolling press, fox Which an ordinary copying press may be substituted, £2 2s. The gelatine plates, when used, will be exchanged for new ones by the patentee, win very low price. Each plate will yield from 150 to 200 perfect copies, according to the style of drawing, When larger plumbers are required, the best plan is to take am impression, while the plate is at its best, with transfer ink on transfer paper; if this be sent to a lithographer, more than 5,000 prints can be obtained from each of such impressions, thus multiplying, almost indefinitely, the number of exact facsimiles which can be produced. There is a great advantage in being able to transfer to stone, as any number of sketches can be combined together, or with letter-press printing. The latter is elected by taking an impression from the type with transfer ink, which can then be placed upon the stone with the drawing.

The autographic process is superior to lithography in the delicacy of its results. The only care required in making drawings for this purpose is to keep the lines us fine as possible, and to use only open shading. It is especially applicable to cases where only a limited number of copies is required, as for circulars, examination papers, music, &c., which can be printed at home, but, above all, for securing a record of any original microscopical or other observation; the drawing can he made without any elaborate preparation, and the absolute fidelity of the copies ensured.

Want of space compels the compression of the monthly meteorological article, so that, instead of printing the remarks from each station in full, we must be content with a general summary. Notwithstanding this, we trust that every observer will continue to favour us with as many details as possible. especially of any remarkable occurrences, and of those facts in relation to animal and vegetable life which impart to meteorology much meaning and interest. We have quoted the references by our observers to the now famous "Eurydice squall” of the 24th of March in a special note,

March opened with charming and genial weather, "Coming in likea lamb," but it left us with a very ill grace, "Going out like a lion," thus literally reversing the old proverb. Temperature rose to 61° at Sedgley, on the 7th; and to 60° at Belvoir Castle (7th.) Worksop (1st.) and Dudley (1st.) The nights were very cold from the 22nd to the end of the month. the Cheltenham return of 12.2° (and on the grass 8.5°) on the night of the 25th, being very remarkable, Rainfall was decidedly below the average, and in most places the heavy land was so hard and dry that sowing was rendered impossible. Frequent falls of snow were experienced in the last week, those of the 27th and 28th covering the ground to a depth of 4in, or 6in. At Much Wenlock buttercups were in blossom on the 3rd, and the Wood Anemone on the 6th; Coltsfoot, Daffodil, and Palm, near Hereford, on the 7th. The Chiffchaff was heard at Kibworth on the 21st, and the small Bat seen flying near Stroud on the evening of the 3rd. The remarkable squall of the 24th is noticed separately.
