ent of the urine may be impaired while the others remain perfectly 
intact. In case H. with an acute exacerbation of a chronic affec- 
tion of the kidney due to an attack of tonsilitis, the NaCl elimi- 
nating power was absolutely lost. No precipitate could be ob- 
tained with AgN0 3 after the removal of the albumin, whereas 
on the same days the patient eliminated water, nitrogen and SO3 
perfectly well.

A note on the nature of oxyphilic granulation. 
By HERMAN M. ADLER. 
[From the Danvers State Hospital, Hathorne, Mass.] 
An aqueous solution of eosin will give with ferric chloride a 
precipitate which has a deep red color. If very dilute solutions 
are used, say 0.1 of 1 per cent, ferric chloride, and an eosin solution 
which is just barely pink, no precipitate will be visible on mixing 
the two, but the pale pink of the eosin changes to a deeper shade 
of red, and the fluorescence, which is quite noticeable even at 
this dilution, disappears. If the dilution of the eosin solution 
used be increased so that these color changes can no longer be 
distinguished with certainty, it is possible to demonstrate the 
reaction by the addition of a colloidal suspension of Witte's 
peptone, or of sodium oleate. 
On the addition of such a solution, which should be sufficiently 
strong to cause a well marked opalescence, the red color of the 
iron-eosin stain will at once be apparent, especially where sodium 
oleate has been used, in which case a flocculent precipitate stained 
a rich red will appear. The examination under the microscope of 
such a precipitate, reveals an appearance which, in respect to color
