Excerpt from The Saint Louis Medical and Surgical Journal, Vol. 42: June, 1882 The Missouri Vaccine Farm was established in 1875, for the purpose of supplying physicians with a pure and reliable Vaccine Virus from the heifer, in quantities to suit the demand. Each animal used is under my immediate supervision, from'the 'time it is brought on' the farm until the. Virus is collected from it, so that the greatest care is exercised in produc ing a Vaccine that will reproduce genuine vaccinia upon the human being. Four years of close observation and experience in preparing the Virus from the Animal, and a visit to the State vaccine Institutes at Brussels, Belgium, and Paris, France, in 1878, where only cowpox Virus is used, have enabled me to so perfect my arrangements for producing the Virus that I can supply the largest demands.
