For afew years, teeth treated by this method would be quiescent, butafter about five years 50 per cent or more had abscessed. In1892 the late W. D. Miller suggested a mixture of 3 parts of corro-sive sublimate and 1 part of thymol, compressed into small tabletswhich he used in about the same manner as Baume recommendedfor his borax embalming process. The success obtained with thesetablets has been fairly satisfactory, the bluish-black discolorationof the teeth by the sublimate and the very frequent acute peri-cementitis following the treatment are serious objections.

He prepared a mixture of equal parts of thymol,alum and glycerin with enough zinc oxid to make a stiff paste has been employed with more or less success and from1896 to about 1902 the current literature is filled with reports anddiscussions on this interesting question. In 1898-1899 Bcenneckenrecommended a method of pulp mummification, using a paste con-sisting of cocain, thymol, formaldehyd, zinc oxid and success obtained with this treatment was apparently satis-factory, and his method has gained many friends. Brooks, in1898, offered chromic acid in conjunction with sulphuric acid forsuch purposes. In 1898 Julius Witzel published his experimentswith
