Exudation of low molecular weight carboxylates is an important phosphorus (P) acquisition strategy for plants in strongly P-fixing soils. The effect of citrate exudation on P availability was studied in five acid soils with a large organic matter content and a low available P pool. The amount of molybdate reactive P extracted by citric acid 10 mM (0.1–2 mg kg) was larger than the molybdate reactive P (MRP) extracted by CaCl 2 10 M (0.007–0.07 mg kg). Both extractants were adjusted to soil pH prior to extraction. Also, the total P content of citric acid extracts (2–44 mg kg) far exceeded the total P content of CaCl 2 (0.2–1.5 mg kg). However, ratios of MRP to total dissolved P (TDP) remained constant. When citric acid was added to the CaCl 2 -extracts (the pH of citric acid being adjusted to the pH of CaCl 2 , and thus eliminating release of P through acidification) a significant pH increase was noted. Simultaneously, MRP increased significantly in all but one soil. This suggests that the P availability enhancing properties of citric acid are not only due to acidification of the plant rhizosphere, but also to its Al and Fe complexing capacity.

Georges Gilles de la Tourette died on May 22, 1904, following a slow mental deterioration associated with general paralysis. After a brief history of the disease and its description, the author examines how Gilles de la Tourette’s illness came to light, why he was committed in Switzerland, and the details of his hospitalization, based on unpublished documents from the Loudun archives. His wife played an essential role, attending to her husband during the three years that preceded his death. Her devotion is evident in the many letters she wrote and received, including her correspondence with a number of medical celebrities.
