Abstract
This essay attempts to evidence the remaining echoes of the reception of Mendeleev’s periodic classification in Portugal during the last quarter of the nineteenth century. The research involved the identification of remaining traces at different higher-level teaching institutions as well as with books, textbooks, and programs from beginner’s level to advanced level that appeared in the period between 1876 and 1904. Following the institutionalization of chemistry as an independent scientific discipline in Portugal, after the 1772 reform of Coimbra University, the 1844 reform of the university serves as a breath of fresh air in terms of the study of chemistry as being split into different chemistry specialties, an action much related to developments abroad. By 1851 the Coimbra professor J. A. Simões de Carvalho (1822–1902) was opposing chemistry being taught at the university with French textbooks. Instead, he wrote a modernized text, which included recent research for chemical philosophy lessons and advocated a much greater “attention to the day-to-day communications in scientific journals and newsletters than to more complete and extensive manuals.” In the two decades immediately before the period we are interested in, there was a resurgence of the country’s economy and some developments also affected the still unique university. In this context, reform of curricula took place and a positivist wind blew through the faculties, starting in the Law Faculty and then spreading to the other faculties with a symptomatic decline in the influence of the Canonical Faculty. The Law Faculty had the biggest number of students and several of its members took up higher administrative or governmental positions. The intellectual atmosphere of the Faculty of Natural Philosophy was deeply impregnated with positivism, whereby it was intended to regenerate the sciences body. The program of sending some of its members abroad was reactivated, to keep them up to date with the modern experimental sciences, particularly chemistry, while some foreign staff came to work in the university.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
