function in the brain. Ferrier's strongest evidence was a monkey who suffered from hemiplegia, paralysis affecting one side of the body only, after a cerebral lesion. A committee, including Langley, was made up to investigate. Both the dog and the monkey were chloroformed. The right hemisphere of the dog was delivered to Cambridge for examination. Sherrington performed a histological examination of the hemisphere, acting as a junior colleague to Langley. In 1884, Langley and Sherrington reported on their findings in a paper. The paper was the first for Sherrington. Travel In the winter of 1884–1885, Sherrington left England for Strasbourg. There, he worked with Goltz. Goltz, like many others, positively influenced Sherrington. Sherrington later said of Goltz that: "[h]e taught one that in all things only the best is good enough." A case of asiatic cholera had broken out in Spain in 1885. A Spanish doctor claimed to have produced a vaccine to fight the outbreak. Under the auspices of Cambridge University, the Royal Society of London, and the Association for Research in Medicine, a group was put together to travel to Spain to investigate. C.S. Roy, J. Graham Brown, and Sherrington formed the group. Roy was Sherrington's friend and the newly elected professor of pathology at Cambridge. As the three travelled to Toledo, Sherrington was skeptical of the Spanish doctor. Upon returning, the three presented a report to the Royal Society. The report discredited the Spaniard's claim. Sherrington did not meet Santiago Ramón y Cajal on this trip. While Sherrington and his group remained in Toledo, Cajal was hundreds of miles away in Zaragoza. Later that year Sherrington travelled to Rudolf Virchow in Berlin to inspect the cholera specimens he procured in Spain. Virchow later on sent Sherrington to Robert Koch for a six weeks' course in technique. Sherrington ended up staying with Koch for a year to do research in bacteriology. Under these two, Sherrington parted with a good foundation in physiology, morphology, histology, and pathology. During this period he may have also studied with Waldeyer and Zuntz. In 1886, Sherrington went to Italy to again investigate a cholera outbreak. While in Italy, Sherrington spent much time in art galleries. It was in this country that Sherrington's love for rare books became an obsession. Employment In 1891, Sherrington was appointed as superintendent of the Brown Institute for Advanced Physiological and Pathological Research of the University of London, a
