Samuel Hart, Popular Science Monthly (1884)
“ A life-insurance agent brings to his company's medical examiner an individual whom he considers an exceptionally "good risk." He has the facial appearance, the physique, and record of perfect health. The examiner, in making up the rigid descriptive list for his company, must assure them, as "parties of the first part," that in this case the sounds of the heart are perfectly natural; that its movements are entirely correct as regards their rhythm, strength, and frequency; that the pulse does not intermit, etc.; and that there is no disease or morbid condition, or tendency thereto. ”
