 The structureless skin of the retina 

 is finely brought out by anilin red, 

 even after treatment by perosmic acid.

 For permanent preparations the fol- 

 lowing dye is recommended : — To a 

 dilute watery solution of rosanilin add 

 by drops tannic acid till all the color 

 is precipitated (a slight residue will 

 always remain) . Wash and dry the 

 precipitate, and dissolve in alcohol 

 with a few drops of acetic acid. The 

 preparations should not be mounted 

 in glycerin or balsam, but in sugar 

 syrup, to which 3 to 4% of sodium or 

 calcium chloride has been added.

 Eosin, the potassium salt of tttra- 

 bromfluorescin, is red with green fluo- 

 rescence, and dyes sections in water 

 in 10-12 hours. It is better to pre- 

 cipitate it by acids, filter, and dissolve 

 in alcohol, 1-20 or 30. May be used 

 on objects treated by Midler's fluid, 

 and on fresh specimens, which are by 

 it hardened and stained at the same 

 time. Epithelium, muscular fibre, 

 axis cylinders and blood vessels stain 

 of a beautiful red, connective tissue 

 and nerve cells less readily, and the 

 medullary matter not at all. The 

 amyloid substance of degraded or- 

 gans stains deeply.

 Leonhardt's violet ink, which is 

 only a mixture of blue and red ani- 

 lins, stains amyloid portions of tissue 

 a beautiful rose red, while the rest is 

 made blue.

Jtirgens recommends iodine violet 



in water for the same purpose as in 



82. Those parts showing amyloid 



degeneration stain a clear red, while 



the remainder appear violet blue. A 



little time is necessary to produce the 



best results, during which the colors 



deepen somewhat.
