This portion of the collection contains specimens derived originally 
from the unmounted non-exsiccati materials described in the third part 
of the 1857 bequest. A Catalogue of the Unmounted Materials [of the] 
Bailey Collection in the Boston Society of Natural History , which was 
produced in i 860 , has been the sole measure of materials appropriate 
to this part of the Collection. This Catalogue was initially the 
property of the Society, but by 1938 and by unknown means it had passed 
into the possession of Clarence A. Cheever, an amateur Massachusetts 
diatomist. It lists 705 samples, primarily infusoria, representing an 
unknown proportion of the original amount of material, but also contains 
notes by Cheever indicating that many of the samples were either missing 
or contained so little material as to be useless. I have found in the 
Farlow Herbarium a loosely grouped collection of 100 vials designated 
collectively as "Bailey Collection ex B.S.N.H." These vials were 
apparently the gift of Cheever in 19^-1 or 19^-3 along with the i860 
Catalogue , but these vials have plastic screw caps indicating they are 
not the original containers of Bailey eventhough the material inside 
may be his. However, because none of these vials bears any identifying 
notes or numbers and because I have been unable to determine how Cheever 
secured them, I have not included them in this accounting of the collection. 
Also, in 1976, I found loose among miscellaneous papers pertaining 
to the diatom collections in the Farlow Herbarium an undated unsigned three- 
page note entitled "Bailey Collection. Unmounted Materials." describing 
a collection of boxes, dry mounts, etc. contained in a small cabinet; 
the materials were in accord with entries in the i860 Catalogue . Because 
the note makes reference to the cabinet being associated with several 
volumes of Bailey’s letters and notes, which are still in the possession 
of the Boston Society of Natural History (now Boston’s Museum of Science),
