Here's a different approach Rousseau, for botany. The text body understand 350 pages, the rest are notes but especially the annexes that are just as interesting (lists of botanical works of Rousseau, the symbols that he developed to describe plants ...). The first part I was more interested than the second. It relates to learning botany Rousseau, how it herborisait for example. The second is devoted to Rousseau botanical consultant. The author in his writings husked to reclassify then. The book is designed as an alternate e comments and quotes. On the occasion, we also learned a little more about his character. He was not to be as easy as you think. 4 stars because the book is not shown.
