Preservation. The modes of preserving material are so vari ous with different cases as to permit only a very general statement. All soft bodied animals must be preserved in alcohol; drying will shrink and alter them too much to leave them available for later study. The alcohol used should be at first weak (30 per and then gradually replaced by stronger till a strength of 80 per cent. Is reached. The water extracted from the animal weakens the alcohol. Alcohol which has been used once can be saved and filtered and used as a first bath in subsequent cases, and over and over till it has entirely lost its strength. Alcohol which will not burn is not fit to use for any but perhaps a first bath. Insects and shells which have had their contents removed can be dried; the insects should be pinned on entomological pins and placed in special boxes which are dust and moth proof.
