Extrait
1Hewson was born in Hexham in 1739.1 He went to London in 1759. He was the student and the anatomy provost of both Hunters. He became a professor and a practitioner and died in 1774 at the age of thirty-five from an injury he sustained when dissecting.
2His main contribution was the discovery of lymph vessels in oviparous animals. He observed them in birds, tortoises, and fishes. He showed that these animals had two thoracic ducts while men and quadrupeds only had one. He recognized that lymph vessels all ended in the thoracic duct and originated from all points of the body, whether or not there were lymph nodes or conglobate glands. Birds, except in their neck, reptiles, and fishes did not have lymph nodes. These organs, which were compared to neural ganglia, only existed in viviparous animals, men, quadrupeds, and cetaceans.
