Alexis Caswell

"The , no less than the severest utilitarian, rejoices in every contribution of science to the arts, but he does not admit that the whole value of science is to be measured by any present applications. He puts in a demurrer to the conclusion that those portions of it are useless of which we do not see the utility. The use may be beyond our present sphere of vision, or, if coming within our cognizance, it may not admit of comparison with any standard of measure. Unlike the precious gem, which has an exchangeable but no intrinsic value, science bears no price in the market. It transcends all ideas of comparison and exchange. Its high utility lies in the breadth and dignity and sublime grandeur which it gives to the human mind."

"Dr. Caswell’s predilection was for and astronomy. During the period of twenty-eight and a half years (from December, 1831, to May, 1860) he made, with few interruptions, a regular series of meteorological observations at the same spot on . These observations, precise as regards temperature and pressure, and including also much information on winds, clouds, moisture, rain, storms, the , &c, have been published in detail in Vol. XII of the "Smithsonian Contributions to Knowledge," and fill 179 quarto pages. Dr. Caswell continued his observations in meteorology with unabated zeal to the end of 1876, covering, in all, the long period of forty-five years."

"There are in astronomy refinements of method, both practical and theoretical, which can be appreciated only by rare gifts and profound study. But the elementary methods are quite within the reach of ordinary minds. The , which it was difficult to discover, may be very easily understood and its results readily traced. It might require a Newton or a La Place to unveil the mechanism of the heavens, but when that is once done every beholder may watch the wonderful evolutions."
