Page 248 - ... inconvenience. The beautiful simplicity of the fact that the line of foci of the different orders of the spectra are on the circle described above leads immediately to a mechanical contrivance by which we can move from one spectrum to the next and yet have the apparatus always in focus; for we only have to attach the slit, the eye-piece and the grating to three arms of equal length, which are pivoted together at their other ends and the conditions are satisfied. However we move the three arms...
Page 248 - IT is not many years since physicists considered that a spectroscope constructed of a large number of prisms was the best and only instrument for viewing the spectrum where great power was required. These instruments were large and expensive, so that few physicists could possess them.

Page 65 - Brief review of the most important changes in the industrial applications of chemistry within the last few years.
Page 249 - Langley's experiments on the ultra-red portion of the spectrum, and was thus made very bright in the first spectrum. The definition seems to be very fine, notwithstanding the short focus, and divides the 1474 line with ease. But it is difficult to rule so concave a grating, as the diamond marks differently on the different parts of the plate. These give illustrations of the results accomplished, but of course many other experiments have been made. I have not yet been able to decide whether the definition...
Page 164 - By this leter it appears in what state ye affairs of ye plantation stood at this time. These goods they bought, but they were at deare rates, for they put 40. in ye hundred upon them, for profite and adventure, outward bound; and because of ye vnture of ye paiment homeward, they would have 30.* in ye 100.
Page 98 - ... lives to this work. My desire would be that each pupil should spend four years at a German university — three of those years to be devoted to the acquisition of knowledge, and the fourth to original investigation. "If however in the progress of science in the United States, it should at any time appear to the said board that the end herein proposed would be better subserved by granting aid to...
Page 248 - In this case the spectrum as viewed by the eyepiece is normal, and when a micrometer is used the value of a division of its head in wave-lengths does not depend on the position of the slit, but is simply proportional to the order of the spectrum, so that it need be determined once only. Furthermore, if the eyepiece is replaced by a photographic camera the photographic spectrum is a normal one. The mechanical means of keeping the focus is especially important when investigating the ultra-violet and...
Page 223 - The Biological Laboratory has been open for eight hours daily during the year, for the prosecution of advanced study and research, and for courses of practical instruction in connection with classes.
Page 248 - I hoped to make a practically perfect screw ; and so important did the problem seem that I immediately set Mr. Schneider, the instrument maker of the University, at work at one. The operation seemed so successful that I immediately designed the remainder of the machine, and have now had the pleasure since Christmas of trying it. The screw is practically perfect, not by accident, but because of the new process for making it ; and I have not yet been able to detect an error so great as one one-hundredthousandth...
