  [1] Includes phenol-cresol mixtures, cresol-cresylic acid
  mixtures, and cresol-xylenol mixtures. For 1937, where it is
  possible, the totals of tar-acid mixtures are broken down into
  these three groups.

Processes of resin manufacture.

The processes of and patents for the manufacture of tar-acid-formaldehyde
resins are numerous. No attempt is made here to describe in detail the
several processes of manufacture or the endless number of variations and
modifications. In general the processes in operation may be designated
(_a_) one stage wet, (_b_) two stage wet, and (_c_) dry.
