Oops

A doctor is going round the ward with a nurse and they come to the first bed where the chap is laying half dead.
"Did you give this man two tablets every eight hours?" asks the doctor.
"Oh, no," replies the nurse, "I gave him eight tablets every two hours!"
At the next bed the next patient also appears half dead.
"Nurse, did you give this man one tablet every twelve hours?"
"Oops, I gave him twelve tablets every one hour," replies the nurse.
Unfortunately at the next bed the patient is well and truly deceased, not an ounce of life. "Nurse," asks the doctor, "did you prick his boil?"
"OH MY GOODNESS!" replies the nurse.

Ida Henrietta Hyde

Died 22 Aug 1945 at age 87 (born 8 Sep 1857).American physiologist who invented the microelectrode in the 1930's. This small device stimulates a living cell either chemically or electrically, and records the electrical activity within the cell. Her firsts include being the first woman to graduate from the University of Heidelberg (1896), to do research at the Harvard Medical School (in the Department of Physiology) and to be elected to the American Physiology Society. The microelectrode has been said to have revolutionized neurophysiology. She researched animal cardiac movement, circulation, respiration, and nervous systems. She investigated the breathing mechanism of the horseshoe crab and the grasshopper, and the respiratory center of the skate, amphibians, and mammals.
