My 7 year-old nephew showed me with pride the "telephone" he had just made from a string and two tin cans.
I pulled out my iPhone and said, "That's nice, but... look at the phones that kids your age are making in China!"

He was also important for his studies on pancreatic juice (1663) and on the reproductive organs of mammals. He is considered one of the creators of experimental physiology. He used a technique of injecting dye into organs in order to be able to observe them better. It was on this technique that a bitter priority dispute with Swammerdam developed. He wrote a brief tract on the use of the syringe in anatomy (1669). He died, perhaps by suicide, at only 32 years of age.Name also spelled Regnier. Day of death given as 21 Aug in DSB. 17 Aug in Enc.
