Shoemakers paste

Flax is sold in balls the thick yellow Is the best. It is named indifferently, nax or hemp. It is much used by shoemakers and is sold at the leather shops. Two or three thicknesses of this, waxed, or drawn through the hand with a little paste, is very convenient for passing round the necks of small choked cases, tying cases on wheels, etc. 

A number of laser based temporal domain experiments have evolved in the past two decades which have no equivalents in conventional spectroscopic technique as they exploit the coherence inherent to stimulated sources. The origin of these methods traces directly to techniques which are widely utilized in NMR and ESR spectroscopy to determine various relaxation and dephasing times. In fact, much of the terminology from magnetic resonance processes has been carried over to laser driven coherent transient studies. See Shoemaker (1978), Levenson (1982) and Brewer and DeVoe (1984).
