current additions of flowering plants have been mounted and 
incorporated in the permanent collections. 
The method of poisoning specimens with mercuric chlorid 
has been continued and as a result all apparent insect life has 
disappeared from the herbarium cases. 
(6) Bulky specimens. A total of 4,600 specimens, mainl 
fungi, were permanently disposed in boxes of the following

In addition to the fungi, the crustaceous and otherwise 
bulky lichens and the myxomycetes, heretofore merely stored, 
were placed in boxes and arranged in the cases so as to be 
accessible for study. 
3. ARRANGEMENT OF THE HeRsaria. Changes in the 
general arrangement of the herbaria were necessitated both on 
account of the growth of the collections and the disposition of 
the new furniture. The myxomycetes and algae occupy the 
laboratory directly west of the library reading room. The 
lichens, fungi and pteridophytes occupy the taxonomic lab- 
oratory. Adjacent to this laboratory and opening into it is a 
room devoted entirely to the collection of bryophytes. The 
main herbarium room is now given over to the seed-plants or 
flowering plants, those comprising the Garden herbarium 
being in the eastern side of the room, those comprising the 
Columbia herbarium on the west. 
(a) Garden Herbarium. A total of 83,643 specimens was 
received for the Garden herbarium. From these and from 
sets of specimens previously acquired, 31,134 sheets, contain- 
ing 41,200 specimens were mounted and incorporated in the 
permanent collections.
