Life of Elie Metchnikoff, 1845–1916. By Olga Metchnikoff — It was at Messina ... that what Metchnikoff regarded as the great event of his scientific life occurred. It is described by him in his own words as follows: — “One day, when the whole family had gone to a circus, I remained alone with my microscope, observing the life in the mobile cells of a transparent starfish larva, when a new thought suddenly flashed across my brain. It struck me that similar cells might serve in the defence of the organism against intruders. I felt so excited that I began striding up and down the room ... [I]f my supposition was true, a splinter introduced into the body of a starfish larva ... should soon be surrounded by mobile cells ... I fetched some rose-thorns and introduced them under the skin of some beautiful starfish larvae ... I was too excited to sleep that night in the expectation of the result of my experiment, and very early the next morning I ascertained that it had fully succeeded. That experiment formed the basis of the phagocyte theory“.

I trust you will kindly allow me space for a few lines on the subject of some rare specimens connected with the History of Photography, now in the possession of Madame Nièpce de St. Victor, whose husband it will be remembered was the first to employ glass, and a transparent medium (albumen) for the purposes of photography, thus discovering, to a great extent, the process of Photography as it exists at the present day. The first glass negative, or rather cliché, Madame Nièpce possesses, as likewise prints executed in 1848. Nièpce de St. Victor was ... one of those who have worked hard to secure natural colours in the camera, some very perfect specimens — photographs of coloured dolls — which prove distinctly that the solution of the problem is not impossible, as many believe, are also included in the Nièpce collection.

Jul 5, 2014 · Mechnikov discovered phagocytes, immune cells that protect organisms by ingesting foreign particles or microorganisms, by conducting experiments on starfish larvae. He then developed a theory of the cellular process involving phagocytes, known as phagocytosis, to explain how inflammation is a part of the self defense system found in both ...
At Messina he discovered phagocytosis after experimenting on the larvae of starfish. In 1882 he first demonstrated the process when he inserted small citrus thorns into starfish larvae, then found unusual cells surrounding the thorns.

May 31, 2011 · Metchnikoff stuck rose thorns into starfish larvae and was surprised to see that many phagocytic cells in the hemolymph surrounded the “foreign object”. He also observed the process in Daphnia, which he infected with yeast.
