The basis of the program is the systematic study of the various
organs using histological techniques.  Preparation of stained slides
through sections prepared through the dioxane-paraffin technique
have been shown and taught and learned.  Staining methods - using
such different stains as hematoxylin, methylene blue, eosin,
Wright's, fuchsin, gentian violet, picric acid, osmic acid (if
obtainable) are to be thoroughly learnt as a function of their
specific uses.  We hope to employ the alcohol ether_celloidin
technique this term in preparing sections.  Concerning the tissues
to be covered, we have already studied smears and whole mounts of
blood, and are now working on connective tissue.  The beginning
of the term was denoted to fundamentals. The techniques in histology
are already familiar to you, so that repitition is to be avoided,
but in the course of this and next term, the following organs are
to be studied carefully through slides we are to prepare of them.
Plans and some preparations have already been made.

                    The tissues

The blood:  - smears and action of reagents on whole mounts

Connective tissues - teased white and yellow fibers; sections of tissue.

Muscle - teased preparations after Ranvier's 33% alcohol and
stained sections.

Nerve fibers - teased preps and sections.  We hope to get some osmic
acid without burdening the club with its expense.

The heart - sections from rabbit organ

The blood - vessels - sections from rabbit

The spleen, tonsil and thymus - sections, and, for spleen, teased
preparations.

The four most important endocrines: adrenal, thyroid, parathyroid,
pituitary.

And this is all we propose to do this term.
