We have no time or space here to describe Professor Langley's "bolometer;" it must suffice to say that it seems to stand to the thermopile much as that does to the thermometer.    From Wordnik.com.  [Scientific American Supplement, No. 443, June 28, 1884] Reference

Professor Langley is at work upon it with new and specially constructed apparatus, including a "bolometer" so sensitive that, whereas previous experimenters have thought themselves fortunate if they could get deflections of ten or twelve galvanometric divisions to work with, he easily obtains three or four hundred.    From Wordnik.com.  [Scientific American Supplement, No. 443, June 28, 1884] Reference

"The new scintillating bolometer has performed excellently, proving its viability as a detector in experiments to look for dark matter, and also as a gamma spectrometer a device that measures this type of radiation to monitor background radiation in these experiments", says García Abancéns.    From Wordnik.com.  [A Prototype Detector for Dark Matter in the Milky Way | Universe Today] Reference

On the other hand Ericsson and, more recently, Professor Langley -- who used a bolometer of his own invention for measuring the heat of the sun's invisible rays -- came to the conclusion that even under continued sunshine the temperature would rarely, if ever, rise above the freezing point of water.    From Wordnik.com.  [To Mars via The Moon An Astronomical Story] Reference

The researchers from the University of Zaragoza (UNIZAR) and the Institut d'Astrophysique Spatiale (IAS, in France), made assumptions about the nature of dark matter based on theoretical studies, and developed device called a "scintillating bolometer" to detect the result of interaction of dark matter with material inside the detector.    From Wordnik.com.  [A Prototype Detector for Dark Matter in the Milky Way | Universe Today] Reference

Accordingly, if lines analogous to the dark "Fraunhofer lines" exist in this invisible region, they will appear (if I may so speak) to the bolometer as cold bands, and this hair-like strip of platina is moved along in the invisible part of the spectrum till the galvanometer indicates the all but infinitesimal change of temperature caused by its contact with such a "cold band.".    From Wordnik.com.  [Scientific American Supplement, No. 363, December 16, 1882] Reference

But there is the argument that, if such waves exist, they must be detected by means of our scientific instruments -- instruments so delicate and subtle that they are able to measure the difference of the pull of gravity of an article when placed on the table or on the floor, or can register the heat of a candle at a distance of more than a mile (Langley's bolometer).    From Wordnik.com.  [The Problems of Psychical Research Experiments and Theories in the Realm of the Supernormal] Reference
