Description
The microscope has a sliding coarse adjustment and screw fine adjustment, rectangular stage with condenser, single objective lens, and a brass construction. A magnifying glass is attached to the frame.
Used by Professor Edward H Embley (1861-1924).
Edward Henry Embley (1861-1924) an anaesthetist, Embley showed early promise in chemistry and mathematics. He was registered as a pharmacist in 1882 and took on a small business in Melbourne.
In 1884 Embley began a medical course at the University of Melbourne, supporting himself by pharmacy. He graduated M.B., B.S. in 1889, proceeding M.D. by thesis in 1901. Entering general practice in La Trobe Street, he was soon in demand as an anaesthetist. He was honorary anaesthetist at the (Royal) Melbourne Hospital in 1895-1917, an honorary consultant in 1917-24, and lectured on the subject at the university from about 1900 to 1919.
Embley is remembered for his study of chloroform. This anaesthetic was known to depress the respiration and circulation, and to damage the liver and kidneys. It could also cause sudden death in the induction stage. Embley rejected the Hyderabad Commission's findings of 1889-91 that these deaths were due to respiratory failure, a view which ignored the sudden deaths. In 1899 he went as a week-end volunteer to the university's physiology department, to work under Sir Charles Martin. The upshot was his classic paper of 1902. Embley proved sudden death under chloroform to be due to cardiac, not to respiratory failure. His paper aroused world wide interest. Henceforth, chloroform was to be given progressively, close watch upon the pulse and avoidance of surgical interference until anaesthesia was complete.
