Appendix—Manometric determination of the solubility of oxygen in liquid paraffin, olive oil and silicone fluids

moist cerebral cortex was increased by electrical pulses and the increase opposed by certain added agents.6. Formation of lactic acid by cerebral tissues in minimal aqueous fluid was closer to its normal in vivo value than was its formation with the con- ventional excess of saline.7. A considerable level of phosphocreatine could be maintained in moist cerebral tissues for at least 75 min., while they respired at 370 in oxygen.We are greatly indebted to the Board of Governors of the Bethlem Royal Hospital and Maudsley Hospital for support from the Hospital Research Fund for these studies.
