Practices
Ghost hunters may carry thermographic cameras and infrared thermometers (which can only detect surface temperatures, rather than ambient air temperatures) to detect the presence of purported cold spots in the ambient air of locations that are reported to be haunted. Ghost hunting organizations advise that the spots be checked from several different angles in order to confirm their existence and features.
Ghost hunters prefer to use heat detecting devices rather than reports of feeling cold because the sensation of cold air could be caused by wind chill. Also, a space may feel cold to one person while it feels warm to another.

Famous quotes containing the word practices:
“To learn a vocation, you also have to learn the frauds it practices and the promises it breaks.”
—Mason Cooley (b. 1927)
“Of all reformers Mr. Sentiment is the most powerful. It is incredible the number of evil practices he has put down: it is to be feared he will soon lack subjects, and that when he has made the working classes comfortable, and got bitter beer into proper-sized pint bottles, there will be nothing left for him to do.”
—Anthony Trollope (1815–1882)
“Such is the art of writing as Dreiser understands it and practices it—an endless piling up of minutiae, an almost ferocious tracking down of ions, electrons and molecules, an unshakable determination to tell it all. One is amazed by the mole-like diligence of the man, and no less by his exasperating disregard for the ease of his readers.”
—H.L. (Henry Lewis)
