Report of Conservator. — In making his report for the year, the 

 Conservator of the Botanical Section is pleased to be able to state, 

 that the work in the herbarium has been carried on in the usual 

 satisfactory manner, though the amount accomplished has been 

 necessarily limited. 



The rearrangement of the herbarium, referred to in last year's 

 report as in progress, was completed in the early part of the present 

 year, bringing all the flowering plants, with the exception of some 

 special collections, together in the two rooms on the library floor. 

 This arrangement will be found of great convenience to those 

 making use of the herbarium for comparative study. 



The work of mounting the general herbarium has been con- 

 tinued during the year, the specimens being prepared and names 

 verified as usual by Mr. iNIeehan. The additions received have 

 been the herbarium of the late Wilham Wynne Wister, presented to 

 the Academy in the early part of the year by his family, and com- 

 prising several thousand plants, mostly North American. The speci- 

 mens are all in an excellent state of preservation and will make 

 an interesting addition on account of containing specimens from 

 many localities in or around the city, which have now been de- 

 stroyed. 



Six hundred specimens of Mexican plants have also been added 

 through purchase from the interest of the Redfield Fund, together 

 with about three hundred specimens of Pennsylvania plants from 

 Pike and Somerset counties, presented by Messrs. C. F. Saunders
