"La vérité sur le prétendu Silphion de la Cyrénaïque : ("Silphium cyrenaicum",…" by F. Herincq is a scientific pamphlet written in the late 19th century. It is a botanical and therapeutic critique that challenges the identification of a modern plant from Cyrenaica as the famed silphion of antiquity, and questions the medical claims attached to it. The work dismantles the claim that the so‑called Silphium cyrenaicum equals the ancient silphion, demonstrating instead—through seed, leaf, root, and anatomical comparisons with herbarium specimens and literature (Viviani, de Candolle)—that it is simply Thapsia garganica. Field evidence from M. Daveau’s expedition to Cyrenaica confirms the match and refutes assertions about “tracing” roots and universal seed destruction. The book contrasts ancient descriptions (parsley‑like leaves, edible parts, culinary use) with the modern plant’s vesicant, dangerous resin, and rejects coin imagery as unreliable for species diagnosis. It also scrutinizes promotional medical claims (phthisis, meningitis, etc.), reproducing a decisive letter from Dr Chartier denying therapeutic benefit and noting failures and risks. An appendix critiques contemporary brochures and clarifies sources, ending with the firm conclusion that the celebrated silphion remains lost while the marketed substance is merely Thapsia garganica.

"An atlas of gas poisoning by Great Britain. Medical Research Committee" is a scientific medical atlas produced in the World War I era. It presents official, instructional illustrations and notes for medical officers on the effects of chemical warfare agents, focusing on phosgene and mustard gas. The likely topic is the pathology, clinical presentation, and practical implications of gas injuries to the lungs, skin, airways, and eyes. The book explains that phosgene, a pulmonary irritant, causes immediate respiratory discomfort followed by delayed but rapidly progressive lung oedema, alveolar rupture, vascular congestion, and small-vessel thrombosis, leading to “blue” or “pallid” asphyxia and early death in severe cases; brief case notes and a lung micrograph demonstrate these changes, with mention of oxygen and venesection as supportive measures. Mustard gas, a vesicant, acts with delayed onset, producing intense conjunctivitis, diffuse skin erythema, blistering, and later brown staining, with particular vulnerability of moist skin areas and the perineum; in the airways it causes sloughing of tracheal and bronchial mucosa, secondary infection, and septic broncho‑pneumonia, while lung sections show bronchiolar necrosis and peribronchial haemorrhage rather than generalised oedema. The atlas also stages ocular burns from acute damage to resolution, noting risks of corneal ulceration and outlining supportive care (early atropine and cleansing, later astringents). Throughout, concise plate descriptions, case sketches, and histology highlight the distinct mechanisms, timelines, complications, and recovery patterns of these two agents.
