206 METHODS AND FORMULAS F 2300.0000-F 2500.1030 



2300.0000 Platinic-mercuric 



This is an admirable fixative, particularly before complex staining techniques. Where 

 nuclear fixation is of importance the acidified mixtures of the next class should be used.

formula: water 250, platinic chloride 0.7, mercuric chloride 3.75 



2300.0000 Rabl 1894 23632, 11:165 



formula: water 250, platinic chloride 0.625, mercuric chloride 4 



2300.001 Platinic-mer curie-acetic 



2300.0010 Bouin test. 1910 Spuler EhrUch, Krause, et al. 1910, 2:523

2300.0010 Hoffmann 1908 23635, 89 :598 



formula: 25% ale. 250, platinic chloride 1.25, mercuric chloride 4.5, acetic acid 12.5 



2300.0010 Lenhossek 1898 1780, 51 :220 



formula: water 250, platinic chloride 1.25, mercuric chloride 6.4, acetic acid 12.5 



2300.1 000 Platinic-mercurie-formaldehyde 



2300.1000 Sziits 1913 23632,29:290 



formula: water 190, platinic chloride .625, mercuric chloride 7.6, 40% formaldehyde 

 62.5 



2300.1 030 Platinic-mereurie-formaldehyde-formic 



It is unfortunate that the name of Bouin should be so widely associated with picric- 

 formaldehyde-acetic mixtures. Undoubtedly the best general-purpose fixative which he con- 

 tributed is the only present occupant of this class. It gives a better general-purpose fixation 

 than does the more generally employed "Bouin's fluid," and permits better and more billiant 

 after-staining. 



2300.1030 Bouin 1898 2844, 6:54 



formula: water 180, platinic chloride 1, mercuric chloride 4.2, 40% formaldehyde 60, 

 formic acid 30 



2356.0000 platinic-mercuric-picric-chromic 



2356.0000 von Pacaut 1906 1823, 8 :438 



formula: water 250, platinic chloride 0.1, mercuric chloride 17.5, picric acid 3.5, chro- 

 mic acid 5 



note: This formula is referred by Mayer 1920 to Pacaut 1905 see 6593 (1905) :407. 

 Spuler 1910 (Ehrlich, Krause, et al. 1910, 2 :522) refers to Pacaut 1905 but gives the 

 1906 journal reference.

2500.0010 Platinic-picric-acetic 



2500.0010 vom Rath 1895 766, 11 :282 



formula: water 250, platinic chloride 1.25, picric acid 3, acetic acid 2.5
