โœฆ Synopsis

i69.)--The heating curve and dehydration curve of well-defined crystals of kaolinite from the Glamorganshire coal field were determined. The thermal phenomena exhibited in the heating curve were similar to those of a china clay, a slight terrace in the curve being "due to decrepitation and projection of the material from the crucible. The dehydration test confirmed the result previously obtained, that there is no definite temperature of ,dehydration. The total loss on ignition was 15.94 per cent., but the content of organic matter was large, and some other mineral, possibly halloysite or montmorillonite, was present to' the extent of IO to 15 per cent.

The chemical bond in the hydrogen molecule is examined using the electron density and the generalized overlap amplitudes. Logarithmic derivatives of the electron density provide a clear picture of its behavior in the bonding region as well as in the outer region. The GOA expansion of the density is
