SUMMARY OF EQUIPMENT AND MATERIAL 147 
may be kept constantly ready for use by the simple device of 
suspending from the top a cheese cloth bag containing crystals of 
the sublimate). Absolute alcohol or acetone; xylol or turpentine; 
paraffine (the commercial “parawax” for household use proves 
of excellent quality for ordinary imbedding, and is inexpensive); 
albumen fixative; Canada balsam; iodine (in an aqueous solution 
of potassium iodide); methylene blue (aqueous solution); haema- 
toxylin; eosin (in aqueous or alcoholic solution); Wright’s stain 
for blood; glacial acetic acid; glycerine. For injection of blood 
vessels, pure gelatine (in thin sheets), corn starch, and various 
dry pigments in fine powdered form such as are used by house 
painters. 
VII. FRESH MATERIAL. 
One full-grown guinea pig (or other small mammal) for each 
student (or two students) for the general study of viscera. 
One full-grown rabbit for each two (or four) students, to be 
hardened and preserved for the study of muscles. Certain of 
these may be used first for the demonstration of the general distri¬ 
bution of muscles, and then preserved for later dissection. 
One pig’s foot (anterior or posterior) for each student (or 
each two students). 
One head of sheep or calf for each student (or for each two 
students). 
One fresh mammalian eye for each student. 
Several short lengths of spinal cord (lamb, calf, pig, or cat), 
preferably from different regions, hardened and preserved for 
macroscopic study, for each laboratory division of twelve students. 
One set of thoracic viscera (“plucks”) for each two students; 
these should have the trachea, larynx, and tongue attached, and 
at least one in each laboratory division should have the entire 
liver, and as much as possible of the diaphragm. 
One cat, rabbit, or other mammal for each student (or each two 
students) for injection of blood vessels. These may be preserved 
and dissected later. 
One or more intestinal tracts of cat for each laboratory division 
of twelve students, to be hardened and preserved and cut into 
short lengths for the macroscopic study of the alimentary canal.
