Malpighi (1628-1694),an Italian physiologist,was professor of biology at Bologna. He was an ardent early microscopist using the instrument to view a variety of subjects,including the lungs of frogs & the wing membrane of bats. His observations revealed the finest blood vessels,later called capillaries. His illustrations were based on his observations. Number 46 shows the whole embryonic area at 2 days old. 47 is the embryo on its own. 48 is the enlarged heart region & 49 shows part of the segmented vertebral column | |
