Joseph Lister
1857 On the flow of the lacteal fluid in the mesentery of the mouse

His next paper was a short report based on observations that he made in 1853. This first experiment by Lister, as opposed to purely microscope work, was to prove two goals: firstly to determine the nature of the flow of chyle in the lymphatics and secondly, to determine if the lacteals in the gastrointestinal wall could absorb solid matter, in the form of granules, from the lumen. For the first experiment, a mouse that was fed beforehand on bread and milk was chloroformed and then had its abdomen opened and a length of intestine placed on glass under a microscope. Lister repeated the experiment several times and each time saw mesenteric lymph flowing in a steady stream, without visible contractions of the lacteals. For the second experiment, Lister dyed some bread with indigo dye and fed it to a mouse, with the result that no indigo particles were ever seen in the chyle. Lister delivered the paper to the 27th meeting of the British Medical Association, that was held in Dublin between 26 August to 2 September 1857. The paper was formally published in 1858 in the Quarterly Journal of Microscopical Science.
