Methods used at the Coal Research Establishment of the UK NCB for characterizing the structure and physical properties of cokes and graphites are briefly reviewed. These include the use of X-ray diffraction and optical microscopy, and the measurement of a range of mechanical, thermal and electrical
## Electric Adhesion of Metal Contaets.--A. Stroh has experimented upon tile ~'~dhesion of two metals in mutual contact during the passage of an electric current. Tile adhesion is manifested most strikinly when the metals touch upon two edges crosswise; it changes with the nature of the metal. S~ro
Specific heats of a range of coals, cokes and ashes have been measured from 300 to 600 K (coals, cokes) or 1000 K (ashes) using differential scanning calorimetry. There is a rapid increase of specific heat with the content of volatile matter in the region O-10 wt% followed by only mild increases at
