Another interesting item at the Patagonia Museum that is asked about quite frequently is this contraption that was donated by the Dr. Mock family.
I thought that it might be some kind of anesthesia device since Dr. Mock was an anesthesiologist. I was able to convince a few museum visitors of that until recently one of our docent volunteers, Murphy Musick, researched this machine and was able to identify it as a Jones Motor Basal metabolism tester. It was invented in 1937 and it measures the amount of energy expended per day by a person or animal at rest.
Thank you Murphy!
