THE REFRACTIVE POWER OF LENS AND FLUID 

 MEDIA OF THE MAMMALIAN EYE 



STELLA B. VINCENT 



In the paper on the mammalian eye in this Journal, vol. 2, 

 p. 249, there are errors in the figures for the refractive indices. 

 Mr. H. M. Johnson has kindly called my attention to this and 

 I am very glad to give the corrections. The figures for the 

 lens were omitted from the table and the confusion is caused 

 by misplaced headings. The refractive figures for the horse 

 have been shifted to the raccoon and this is also true of the 

 description of the sensitive area of horse in column three. For 

 fear that there might be other errors I have carefully verified 

 all the factual material in the tables from the original articles. 

 The figures below as they should have appeared in the original 

 table are taken from Gustav Freytag, Die Brechungsindices der 

 Linse und flussigen Augenmedien bei Katze und bei Kainichen, 

 Arch. f. verg. Opth., 1910, Vol. 1.
