424 PEOCEEDINGS OF THE ACADEMY OF [1887. 



Among the additions of the past year worthy of special notice are 

 the following, for which we are indebted to members of the Section : 

 four remittances from Baron F. von Miiller of Melbourne, Australia, 

 through Mr. Meehan, contaiaing 471 species of Australian plants, 

 of which 310 are new to the collection, 52 of them representing new 

 genera : a collection made by Dr. Palmer in the Mexican State of 

 Jalisco, in 1886, embracing 510 species, of which one-half were new 

 to us : and a first instalment of the plants collected by N. N. Rusby 

 in Chili, Bolivia and Brazil in 1885 and 1886, consisting of about 

 450 species. Most of the latter are yet undetermined except as to genus, 

 but it is estimated that about one-half are new to us, many of them 

 being yet undescribed. 



The time and labor required for the proper care of the new addi- 

 tions and for their incorporation into the Herbarium, have some- 

 what retarded the work of mounting the North American portion of 

 it, nevertheless material progress has been made. All of the Poly- 

 petalous and Monopetalous orders are now mounted and some portions 

 of the remainder, leaving less than one-fourth of the work yet unac- 

 complished. In all the work that has been performed, the Conser- 

 vator has been greatly aided by the efficient services of Mr. Isaac 

 Burk. 



In order to provide space for the Martin collection of Fungi, it 

 became absolutely necessary to make some disposal of a large amount 

 of duplicate plants, which had been gradually accumulating through 

 a long period of years, many of them of considerable value, others 

 in bad condition. These by vote of the Section, have been sent to 

 Bryn Mawr College on terms believed to be mutually advantageous, 

 and the proceeds will be used for the increase of the Herbarium. 



A complete list of the additions accompanies this report, and will 

 appear in its proper place, under the head of "Additions to the 

 Museum." 



Respectfully submitted, 



John. H. Redfield, 



Conservator.
