note: This mixture is widely used in continental Europe but was ignored in England 

 and the United States until the formula was reprinted by Linder 1929 (19938, 70 :430). 

 Although Linder correctly acknowledged the source of the formula, many subsequent 

 writers refer to "Linder's Medium" (cf. Carpenter and Nebel 1931; 19938, 70:154). 

 In 1933 (19938, 77:23) Moore suggested the addition of 0.5 phenosafranin to "Lin- 

 der's Medium." This may account for the curious statement in Gatenby and Painter 

 1937, p. 692, that "Linder's Medium is [here is given Amman's mixture] . . . w^ith a 

 small amount of carmine." Some additional confusion has been occasioned by the 

 fact that Linder (loc. cit.) cites an undated text by Satory as his source for Amman's 

 formula; Moore (loc. cit.) then cites the composition as " Satory 's formula as given by 

 Linder." The stains of Maneval 1936 (DS 12.15) are designed for use before this 

 medium.
