[Annual Meeting - . 
The remaining six boxes contain the usual miscellaneous assort- 
ment of a general microscopical collection. They have all, 
however, been carefully catalogued in the Society’s books. 
There is also a small collection of mounted Foraminifera, of no 
special value. They are from the Gulf of Mexico, Nantucket 
Shoals, and Monterey, Cal., the latter being fossils. 
Besides the twenty-four boxes of uniform size above mentioned, 
the collection comprises some 568 slides in odd boxes and par- 
cels. Of these owing to the style of mounting 40 have been 
destroyed, and half as many more would not stand much hand- 
ling. They were mounted with mica covers, which have begun to 
scale off. 
These miscellaneous parcels contain mainly diatoms, 1 though 
some include Foraminifera. The diatoms are named, and many 
are very neatly mounted ; and some of the parcels are well pre- 
served. There is also a small box of desmids ; some chemical 
crystals, a number of slides from chalk, and a small box of French 
mounts, and a section or two of rock or silicified wood, comprise 
the miscellaneous part of the collection. 
This collection also contains a lot of 27 slides, of dry infusorial 
matter, without covers, labeled by Dr Durkee. 
The unmounted material of the Bailey collection is valuable. 
The majority of the boxes and parcels contain diatomaceous earth, 
either fossil-bearing cleaned materials, or mud from dredgings 
and artesian well-borings. The value of the whole lot would be 
very great to a student, many localities being represented, and 
much of the material being now hard to obtain . Professor Bailey 
was in correspondence with scientific men all over the world, 
and many of the samples of earth are accompanied by letters. 
There are a number of parcels of uncleaned deep-sea dredgings, 
which would yield Foraminifera, and evidently were collected for 
that purpose, but all of the unmounted material is more or less 
represented in the collection of slides. Some old fashioned da- 
guerrotypes of diatoms accompany the material, and a book of fine 
drawings of Polycistinae and diatoms. 
The mounted material of the Greenleaf collection is as fol- 
lows : The slides are catalogued as numbering 2,114; of these 
about 1,000 are diatoms, finely mounted, and many sorted and 
named, and are in good condition. 
1 Loose bundles, containing 160 native and 71 foreign diatom-slides.
