C. 23 This is an entirely novel form of Transit made by us for the United States Coast Survey, and designed by G. N. Saegmuller, Chief Mecha¬ nician, U. S. C. S. It is intended to be set up in the prime vertical, so that the telescope points due east and west. By the use of a pris¬ matic objective, any star that passes the meridian will be reflected and seen in the field, as it is evident that when the instrument is set up correctly, by turning it in its'bearings it will sweep the meridian. The pivot-rings are of phosphor-bronze, and, to avoid flexure as much as possible, these rings are again connected by a tube, so that the telescope body is really double. By onei of the three setting-screws the instrument is moved in Azimuth. It is provided with a reversing apparatus, which also carries the illuminating lamp. The fine level over the telescope is held by a projection from the reversing appa¬ ratus, which secures this great advantage, that the level need not be taken off on reversing the instrument; it also stays on whether observing in the zenith or horizon. Behind the micrometric eye-piece, two setting-circles are attached, with level alidades, divided on silver, and reading to minutes. One of these carries also the fine Latitude Level, which is chambered, and reads to single seconds. We make this instrument of different sizes, and being, by nature of its construc¬ tion, of an exceedingly simple and portable form, it is especially adapted for work in a rough or mountainous country.

C 25 ALTITUDE AND AZIMUTH INSTRUMENTS. Cut No. 43 represents one of our larger instruments, which was on exhibition in the International Exhibition at Philadelphia, for which we received an award. It is of superior construction, and differs from other instruments of this class in many important particulars. Not being a “ repeating instrument,” strictly speaking, and, therefore, not liable to the defects inherent to repeaters, yet both the horizontal and vertical circles can be shifted for position, so as to bring a different part of the graduation under the microscopes. The circles are divided on silver into five minute spaces, reading by micrometer microscopes to single seconds. The standards radiate out from the centre, and are high enough to let the telescope swing through. The pivots of the telescope axis rest on agate, and are made of phosphor-bronze; a delicate striding level* reading to seconds, to go over pivots, is provided; pivots are pierced to allow the field to be illuminated; the horizontally of the micro¬ scopes for vertical circle is controlled by a chambered level, reading to seconds. The illumination of the graduation is effected by means of prisms receiving light from above and throwing it out radially, thus insuring the same condition of light in any position of the microscopes. Both circles are entirely free of clamps and tangent-screws, these being attached to a collar, so as not to produce any strain on the circle. No. 43.—Altitude-Azimuth, as described above ; horizon¬ tal circle eighteen, vertical circle twelve inches in diameter; former reading by three, and latter by two microscopes.

It is of much improved construc¬ tion, and exceedingly light and strong. The telescope, having a clear aperture of 2 inches by only 12 inches focal length, gives great brilliancy to the image. The circle is 10 inches diameter, divided on silver, and reads by means of three verniers to five seconds. By botanical Garden «.

Easy and Successful Introduction of the German Language INTO PUBLIC SCHOOLS. I ing a I In the fall of 1810, the German Language became a general branch of instruction in the Male Department of Grammar School No. 15, New York City, in accordance with the amended By-Laws of the Board of Education. Of the 500 boys in the School nearly one half, belonging to American, Irish, Scotch or English families, until six months ago knew nothing whatever of the German language. On Friday, March 31st 1811, an examination was held to test the progress made in the new study. It was demonstrated, on this occasion, in a most satisfactory manner, that though the German boys of course excelled the others in conversational powers, the American, Irish and English boys had learned the action and grammatical construction of the German language surprisingly well, fully equalling the children of German parents. The several grades were examined in succession; the pupils not only read and translated German into English, and English into German, but they also wrote down in correct German script English phrases given them to be rendered into German. At the close of the exercises, Mr. Superintendent Kiddle, who had conducted the examination, congratulating the boys upon their remarkable success in engrafting the German lan¬ guage bn the regular course of study, observed : Very many persons have thought that this could not be done, without sacrificing those English studies which in a practical point of view, are of paramount importance; but you have made the experiment, and under the able and zealous instruction of your excellent teacher, Mr. Hutten, you have achieved that which has given us not only pleasure and satisfaction, but sur¬ prise; for, in six months, to have acquired a facility in German pronunciation, to have learned to translate so large a number of German exercises into English, and vice versa , and to use with so much fluency the German script , is a task of no ordinary magnitude. Indeed, many persons on witnessing this ex¬ amination, might suppose that, during this period, you have done nothing but study German; but I can bear testimony, from the records of my de¬ partment, that the examinations to which this school has been subjected in the ordinary English branches, during the same period, were never more suc¬ cessful or satisfactory. 1 Z7LI* (l&j uJU ) jo - tj copyright reserved FAUTH & CO., WASHINGTON, D.
