Chapter 6

(1) Condensed from Dr. Boerhaave's Academical Lectures on the Theory of Physic. London, 1751, pp. 77, 78. Boerhaave's lectures were published as Aphorismi de cognoscendis et curandis Morbis, Leyden, 1709. On this book Van Swieten wrote commentaries filling five volumes. Another very celebrated work of Boerhaave is his Institutiones et Experimenta Chemic, Paris, 1724, the germs of this being given as a lecture on his appointment to the chair of chemistry in the University of Leyden in 1718.

(2) An Inquiry into the Causes and Effects of the Variola Vaccine, etc., by Edward Jenner, M.D., F.R.S., etc. London, 1799, pp. 2-7. He wrote several other papers, most of which were communications to the Royal Society. His last publication was, On the Influence of Artificial Eruptions in Certain Diseases (London, 1822), a subject to which he had given much time and study.
