Excerpt from A Treatise of the Materia Medica, Vol. 1 of 2 The Lectures on the Materia Medica formerly published in my name, though very incorrect, were so well received by the public, that notwithstanding my endeavours to prevent it, they have been several times reprinted, and even translated into foreign languages. This mark of public favour led me to think of giving a more correct and complete edition of those Lectures; but finding that it was not possible for me to give it, with the corrections and supplements which would be necessary, in a satisfying manner, I have long abandoned that idea, and judged it more proper to give an almost entirely new work; which I endeavour to do in the present publication.
