The aim of this article is to demonstrate the importance of scientific communication of pharmacists in the 19th century. 89 letters were analysed both written received by August Peter Julius Du Menil . In the paper also a summary is given about the importance of extensive activity of the pharmacist Du Menil. He was be in correspondence with 39 scientists, for instance 13 physicans and 12 pharmacists. The letters are an interesting document about scientific community in the 19th century.

Usually one reads that after the foundation of scientific journals the journal article took the place of scientific correspondence. It is shown here that periodicals did not replace the letter, but only supplemented it. Norms were developed for the journal article such that (in short) only the „context of justification”︁, not the „context of discovery”︁, could be discussed. Any scholar who wanted to participate in the „discussion out of which science arises”︁ had to resort to the letter; the reading of (...) journals did not suffice. — This circumstance is illustrated in particular by the example of quantum theory and by Wolfgang Pauli.

Since 1790, the term Naturwissenschaften occurs in the lecture lists of the University of Jena published in the Allgemeine Literatur‐Zeitung of Jena. Naturwissenschaften is used as a title for lectures previously listed under the headings of Philosophie or Naturgeschichte. The introduction of the concept of Naturwissenschaften is interesting for several reasons: Firstly, at that time it is not the usual label in this context, and one therefore has to ask whether it already implies the connotations that are associated with the (...) modern concept of Naturwissenschaften, i. e. science in the modern sense. Secondly, the lecture lists of the University of Jena give insight into the various changes in the established ordering scheme for academic lectures that lead to the introduction of the term Naturwissenschaften, thus contributing to a better understanding of both the history of this concept and of the development of the university faculties as we know them. A close look at the concept of Naturwissenschaften as it was used around 1800 may, thirdly, help to understand the use made of this concept in philosophy, especially in the philosophy of nature of this period.
