The following advantages are claimed for this method: 
1) It causes less shrinkage than any other method. 
2) It shows cell outlines with great distinctness. 
3) Both cell plasma and nuclei are admirably fixed. 
I am informed that good results have been obtained by this 
method both in the case of marine Invertebrates and of recently 
excised Cancers.

The suprarenals of a hibernating hedgehog were removed and 
immediately fixed in G. Mann’s alcoholic picro-corrosive solution!), and 
subsequently embedded in paraffin in the usual way. 
The sections were stained according to M. HEIDENHAIN’s hemato- 
xylin iron alum method ?) and mounted in balsam. 
The Cortex. The Zona glomerulosa is very thin and consists 
of cells arranged in solid or hollow columns in the usual manner; in 
profile they appear columnar in shape, but when viewed from above 
are seen to be large polyhedral flattened cells of irregular shape. 
Each cell possesses a well marked almost spherical nucleus in which 
one or more nucleoli may be seen; the protoplasm is granular and 
devoid of pigment. 
The Zona fasciculata which constitutes the greater part of the 
cortex varies in thickness in different localities, and may be divided 
into two layers: an outer, occupying about a third of the total thick- 
ness, and an inner comprising the remainder. 
The outer layer consists of large polyhedral uninucleated cells 
arranged in dense columns, they exhibit an open, wide-meshed, faintly 
Staining protoplasmic network, a spherical nucleus in which are one
