Undercover Clergy

A minister, a priest and a rabbi went for a hike one day. It was very hot. They were sweating and exhausted when they came upon a small lake. Since it was fairly secluded, they took off all their clothes and jumped in the water.
Feeling refreshed, the trio decided to pick a few berries while enjoying their "freedom." As they were crossing an open area, who should come along but a group of ladies from town. Unable to get to their clothes in time, the minister and the priest covered their privates and the rabbi covered his face while they ran for cover.After the ladies had left and the men got their clothes back on, the minister and the priest asked the rabbi why he covered his face rather than his privates. The rabbi replied, "I don't know about you, but in MY congregation, it's my face they would recognize."

Karl von Vierordt

Born 1 Jul 1818; died 22 Nov 1884 at age 66.German physician and professor of medicine who invented the sphygmograph (1854), the first instrument to trace a human pulse by a non-invasive measurement of blood pressure. His method of using weights and a mechanical balance was crude, but did establish the principle that blood pressure could be measured by finding the counter pressure needed to balance the arterial pulsation. In 1852, he developed a technical method by which blood cells could be counted (though too tedious to gain widespread use). Vierordt also devised the hemotachometer to monitor the speed of blood flow. He made spectrographic analyses of haemoglobin solutions, bile, and urine and also studied respiration and sound conduction.«
