The additions made just previous to the beginning of this 
year to the case equipment of the Fossil Plant Museum inthe 
basement necessitated a complete rearrangement of that col- 
lection, bringing about the doubling in size of the public ex- 
hibit of fossil plants, so that now four table cases are devoted 
to the plant-remains of Paleozoic time, instead of two as here- 
tofore; five similar cases include plant-remains of Mesozoic 
time, instead of three, and three cases contain the remains of 
plants of Neozoic time as compared with the one in the former 
arrangement. A complete description of the arrangement 
and scope of the collections included injthis museum was 
published in the December JOURNAL. 
Two very important additions were presented to the Eco- 
nomic Museum, namely, a collection of between one and two 
hundred specimens representing the sources of various plant 
constituents, and a collection of several hundred specimens 
of varnish resins. The former is being installed with the 
plant constituents in the west wing of the Museum, while the 
latter is being studied preparatory to labeling. The accumu- 
lated specimens illustrating the trunks of trees, secured on 
several former expeditions to tropical America, have been 
sawed into uniform sizes and otherwise prepared, and are 
being installed in the exhibition cases, and progress is being 
made in the installation of general museum material. Dur- 
ing the year such specimens as could not be used in our 
permanent collections were given to the public schools of the 
city or sent as exchanges to other institutions. 
Herbaria 
The more important additions to these collections was the 
Kuntze herbarium, consisting of plants from all parts of the 
globe, purchased by money given by Mr. Andrew Carnegie, 
and the specimens secured by exploration in insular and 
continental tropical America, the larger accessions coming 
from Panama, the Bahamas, Jamaica and Bermuda. 
From the specimens secured during the year and from the 
accumulation of those acquired during former years, about
