Two cows were chatting over the fence between their fields. The first cow said, "I tell you, this mad-cow-disease is really pretty scary. They say it is spreading fast; I heard it hit some cows down on the Johnson Farm."
The other cow replied, "Ah, I ain't worried, it won't affect us ducks."
Marcello MalpighiBorn 10 Mar 1628; died 30 Nov 1694 at age 66. Italian physician and biologist who, in developing experimental methods to study living things, founded the science of microscopic anatomy. After Malpighi's researches, microscopic anatomy became a prerequisite for advances in the fields of physiology, embryology, and practical medicine. Drawing on the work of William Harvey, he studied the circulatory and respiratory systems of all living things and arranged them in a hierarchical system, beginning with plants, above which were insects, then fishes, then the mammals, then man. He was one of the first scientists to study such anatomical structures as the lungs, kidneys, spleen, brain, tongue, and skin at the microscopic level. |
