At the beginning of the 19th c., Francis Whyte Ellis (1777‒1819), one of the major figures of Orientalism, notably as the discoverer of the Dravidian group of languages, wrote in Tamil a treatise in order to persuade Indians to undertake smallpox vaccination, introducing it as the sixth boon from the cow. A manuscript kept in the collections of the BULAC in Paris (Access No. "MS.IND.4") contains the only Tamil version known so far. The present dataset contains pictures of the written pages of the manuscript (first the Tamil version of the text, then its English translation). (anglais)
