I want to know the answer to the following question:
What was the first modern text book?
All the background I'm provided with is that "Botany was greatly stimulated by the appearance of the first "modern" text book, Matthias Schleiden's Grundzüge der Wissenschaftlichen Botanik, published in English in 1849 as Principles of Scientific Botany.". Is that enough to answer the question?
Answer: yes
