7 
loose sheets of foolscap paper. The original notes 
of Prof. Bailey, contained upon slips of paper 
usually loosely wrapped around the slide, were 
faithfully transcribed, and the originals filed 
away for preservation. The whole, amounting to 
372 sheets of foolscap, has been substantially 
bound, and is now available for reference. 
This new Catalogue of the Bailey Microscopical Collection consisting 
of 372 foolscap pages is in the Farlow Herbarium and according to the 
above report assimilated completely and without change in serial number 
slides previously registered in the Catalogue of the Bailey Microscopical 
Slides , which I have not found. The report promotes the expectation 
of the new Catalogue containing 2,l8^ entries - 793 by Bailey and 1,391 
by Miss Washburn. However, the Catalogue describes only slides 
numbered from 567 to 2 , 185 . Although rarely were numbers in this 
series omitted or used more than once, .e.g,. 780 and 780-1/2, the series 
should encompass _c. 1,619 slides. Interestingly, entries numbered 567 
through 2,185 are contained within c_. 372 foolscap pages, and the 
handwriting break in the Catalogue between Bailey and Washburn (which 
is additionally marked by a notation that the transcribers had changed) 
occurs between serial numbers 793 and 79^* At present I have no 
explanation of why the series commences with number 567 and not number 1, 
but I have found neither slides nor references to slides in the collection 
bearing numbers in the range 1 to 566 . I interpret the annual report 
to be misleading in the number of slides that Bailey registered; he 
registered only probably the 227 of them having numbers between 567 and 
793. Also, based primarily on the fact that the Catalogue appears 
complete in having 372 pages, the range of serial numbers provides the 
best estimate of the extent of the collection in 1877 (independent of 
the 1,838 slides reported elsewhere), which I judge to be c. 1,619 slides.
