4700.0000 Cupric-dichromate 



The formula of Erlitzky here given was one of the first fixatives to be widely employed. 

 These mixtures are primarily cytoplasmic fixatives and are not very useful, even after the 

 addition of acid, for the preservation of nuclei. 



4700.0000 Erlicki see F 4700 Erlitzky 1877 



4700.0000 Erlitzky 1877 17035, 5 :739 



formula: water 250, potassium dichromate 6.25, copper sulfate 1.25 

 note: This solution is to be found in almost every text as "Erlicki," presumably copy- 

 ing the statement in Lee 1885, 403 that "This modification of MuUer is known in 

 Germany as Erlicki's solution." The second edition of Lee (1890) gives a reference to 

 a Polish journal. The fifth edition (1900) adds a reference to 1897 (Progres MMicale, 

 No. 39). This incorrect "1897" was continued to the 7th edition where a printer's 

 error changed 39 to 31. This double error has continued to the 11th edition (Gatenby 

 and Beams 1950, 35). These compound errors have been copied by many other texts 

 in which 39 and 31 have been treated both as volume and page numbers. Moreover, 

 the French paper gives the name as Erlitzky.
