not consider that our language is the best possible, but we regard it as one which is susceptible of continuous improvement without its immediate and future use being injured thereby. LEOPOLD PFAUNDLER. APPENDIX I. "LINGUO INTERNACIONA DI LA DELEGITARO." (IDO). The Délégation pour l'Adoption d'une Langue Auxiliaire Internationale, founded in Paris in 1901, has received the support of 310 societies of many countries and the approval of 1,250 professors and academicians. It elected in 1907 an international committee, composed of eminent linguists and men of science, which, after having studied all the projects for international language, adopted Esperanto with certain modifications. These modifications, whilst preserving the principles and essential qualities of Dr. Zamenhof's language, aim at a more logical and strict application of these principles and the elimination of certain unnecessary complications. The following are the principal modifications:-- (1) Suppression of the accented letters, _thus permitting the language to be printed everywhere_, and at the same time preserving the phonetic and frequently re-establishing the international spelling; (2) Suppression of certain useless grammatical rules which are very troublesome to many nations, and _especially to persons possessing only an elementary education_ (accusative, concord of the adjective); (3) Regularisation of the method of derivation, this being the only means of preventing the intrusion of idioms and of furnishing a solid foundation for the working out of the _scientific and technical vocabulary_ so indispensable for the propagation of the language in the scientific world; (4) Enrichment of the vocabulary by the adoption of new stems carefully chosen according to the _principle of maximum internationality_.
