I. _Reading._--The extraordinary ease with which every educated person, and especially anyone who has learnt Latin or one of the Romance languages, can read and understand the language of the Delegation almost without any previous study, indicates that the first stage will not be difficult of attainment. But one would require scientific reading material in order to gain practice in scientific reading, and there we are again faced by a vicious circle. For, in order to create such reading material, we require authors who can write it, and yet the latter can only learn to express themselves in the international language by means of already existing reading material. We must therefore at first make use of the language of daily life and carry over into science whatever is found to be suitable for scientific purposes, after which more sharply defined meanings may be assigned to the words. It has been indicated in the previous article how the remaining special scientific nomenclature can be determined. When this preliminary work is sufficiently advanced the following way will lead quickest to the goal. There will be founded an _international journal_, divided into as many divisions as correspond to the groups of sciences to be dealt with. We have here in view more particularly the theoretical and practical sciences of nature, because they have much more urgent need of an international auxiliary language than the "humanities," whose representatives are more likely to possess a sufficient knowledge of languages. For example, mathematics, mathematical astronomy, mathematical geography, mathematical physics, geodesy, etc., might form one group; general and experimental physics, chemistry and physical chemistry, electrotechnics and applied chemistry, mechanics and mechanical engineering, etc., a second group; mineralogy, petrography, crystallography, geology, etc., a third group; biology, systematic and physiological zoology and botany, morphology, etc., etc., a fourth group. Extensions of these groups and other modes of arrangement might of course be introduced. The foundation at first of several separate periodicals would not be advisable. The following remarks may be made concerning the contents of this journal. In conformity with our plan, it should not at first contain any original articles, for the international language is not intended to replace the natural ones, but only to act as an _intermediary_ between them. Besides, the journal must not contain any insignificant or uninteresting articles if it is to attract and interest readers. But eminent authors, even if they could command the international language, would not publish important original articles in a journal which naturally at first would not have any very great circulation.
