From Science Museum: "Lorenz Heister's (1683-1758) 'A General System of Surgery', published originally in 1743, describes a method for the removal of a tumour from a breast. The image shows the operation in progress.

This print is from the 1780 edition of ‘Dictionnaire raisonée des sciences des arts et des métiers’, edited by Denis Diderot and Jean Le Rond D'Alembert. The title translates as Classified Dictionary of Sciences, Arts and Trades. This was the first French encyclopaedia that aimed to introduce new ideas but also create a record of existing techniques such as those in surgery."]]>
