    Notes: Abstract Conductivities of aqueous solutions ofortho-, meta-, andpara-toluic acids have been measured for the concentration range 0.1–2 millimolar and at 5° intervals from 5 to 100°C. At each temperature pK a(m) andA 0 have been calculated using the paired ion model recently described by Fuoss. Thermodynamic parameters have been calculated for the ionization of each acid, and Walden products for the anions. Results are discussed in terms of contributions to acidity by enthalpy and entropy changes as well as by hydration of the various solute species.

    Notes: Summary The clinical, angiocardiographic, and surgical findings in a cyanotic child with dextrocardia, L-loop, laterally inverted but otherwise normally related great arteries, and situs ambiguus are described and compared with other similar cases. Electrocardiographic, echocardiographic, and angiographic data are reviewed, and thesegmental approach to diagnosis is stressed. Both systemic and pulmonary veins returned to the right-sided atrium. Blood then passed either through the mitral valve to the morphologically left ventricle and to the aorta or through an atrial septal defect to a small left-sided atrium, right ventricle, and pulmonary artery. Total correction was undertaken with an intra-atrial baffle to direct pulmonary venous return to the morphologically right ventricle and systemic venous return to the right ventricle. The subpulmonic stenosis was alleviated with an outflow patch.
