276 Mr. R. H. M. Bosanquet on the History of the 



Konig only answers this question once, where he says that, 

 in beats of the mistuned octave, the octave and fundamental 

 appear alternately. I regard this as a proof that Konig' s 

 notes were not free from octave. As to this see further Helm- 

 holtz, Tonempfindung , 4th ed. pp. 263, 264=; also Preyer, Akus- 

 tische Untersuchungen (Jena, 1879), p. 15. 



On account of the importance of Konig's paper, I have 

 prepared the following list of the rather numerous errata in 

 the copy in the Philosophical Magazine, as also of those in the 

 copy in Poggendorff. It is not possible to read the copy in 

 the Philosophical Magazine with entire comprehension unless 

 the errata have been first eliminated.
