Undercurrents on the Nile: the life of Dr John B Christopherson (1868–1955)
Bibliographic record
Abstract
In the early 1900s, Dr J B Christopherson was one of a small number of British physicians who found their way to Khartoum, the capital of Sudan. The city had been laid waste by the battles of the legendary Mahdi and the armies of the British. Sudan was now considered part of an Anglo-Egyptian Condominium. Christopherson became, partly by force of circumstance, a specialist in tropical medicine. His principal claim to fame, briefly contested for priority, was the treatment of bilharzia (schistosomiasis) by injections of antimonium tartaratum (tartar emetic). The paper sketches Christopherson's turbulent life in Africa and identifies some important events in the life of this man whose energies were directed not only to treating patients and building a medical department in the desert, but also to fighting a rearguard action to preserve his reputation.

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.
