Casts of polythalamia 10^9-1069 
Oregon, California, Puget Sound, 8 II -858 
etc. 
Numbers and titles are taken directly from the original boxes. 
This range of serial numbers delimits all slide numbers contained 
in each box in 1976, when restoration of the collection was begun; 
it does not imply that all numbers within the range were represented 
by slides found at this time. 
In 1976, Boxes #8 and #17 were on loan to the Academy of Natural 
Sciences of Philadelphia and consequently not found initially with 
the rest of the collection. They have subsequently been returned 
to the collection.
