110 REPORT OF NATIONAL MUSEUM, 1921. 
Medicine”; Hippocrates, “ Father of Medicine”; Galen, a noted 
medical writer, sometimes called the “Father of Pharmacy”; 
Avicenna, the Arab medical writer, whose teachings were followed 
by myriads of medical practitioners; Paracelsus, the founder of 
chemical pharmacology and therapeutics; Vesalius, who did much to 
advance the study of anatomy; Paré, a famous French surgeon; and 
Edward Jenner, the originator of vaccine therapy, who extirpated 
the loathsome disease smallpox. These pictures have been framed 
and labeled and are hung on the pilasters above the cases on the 
east gallery. 
A special exhibit of all the books in the sectional library on the 
subject of homeopathy was arranged for the benefit of the delegates 
to the annual meeting of the American Institute of Homeopathy, 
which was held in this city from June 19 to 24, 1921, and many of the 
delegates visited the Museum for the purpose of seeing this exhibit 
and the permanent one arranged to illustrate the history and prin- 
ciples of this school of medicine. 
The southeast court containing the wood collections was closed to 
the public from January 20 to March 3, 1921, in order to permit 
the installation of the large colored transparencies and bromide en- 
largements showing forest stands, lumbering methods, and wood 
utilization. Each of the transparencies was labeled on the glass with 
black letters, permitting the title to be easily read from the floor, even 
at some distance. A specific title in white letters was put on the 
frame below each of the colored bromide enlargements, and four 
large general labels, one for each set of 12 pictures around the four 
sides of the gallery, were mounted above the frame. Upon opening 
the wood court to visitors two bulletin boards were installed, one on 
either side of the entrance, on which to put items of public interest 
concerning woods and their uses. Other installations include a large 
section of British oak from the roof of Westminster Hall; the ex- 
hibit of handmade willow baskets; an assembling of the California 
redwood material, including the refinishing of a large 6-foot board; 
and the exhibition of a Piedmont red-cedar chest. 
PRESENT CONDITION OF THE COLLECTIONS. 
With the exception of slight fading of certain textile fabrics which 
are affected by the light, and the discoloration of certain food sam- 
ples due to exposure to light and heat, there has been but very little 
deterioration of either the exhibit or study materials. The collec- 
tions in the section of wood technology are also in very good condi- 
tion. 
The exhibition and study series of the division of medicine are 
in good condition. It was found necessary to renew the preserving 
fluid on the specimens comprising the exhibit of organotherapy.
