104 REPORT OF NATIONAL MUSEUM, 1921. 
9 medicinal substances from the animal kingdom were presented by 
McKesson & Robbins (Inc.), of New York City; and the H. K. Mul- 
ford Co., Philadelphia, Pa., contributed 4 specimens of antitoxin 
serum and 1 specimen of vaccine virus. 
The “ Medicinal Forms” exhibit was enhanced by the addition of 
22 photographs contributed by Parke, Davis & Co. These pictures 
were made especially for the Museum, and illustrate the workings of 
a modern pharmaceutical manufacturing plant. They show the crude 
drugs as received from the market; vacuum driers; percolators for 
extracting soluble medicinal constituents; how pills, tablets, capsules, 
and suppositories are manufactured, counted, and bottled by machin- 
ery; how pastes and ointments are placed in collapsible tubes, ete. 
A needlework illustration of enlarged microscopic views of animal 
cells, tissues, and blood crystals was presented to the division by Dr. 
J. S. Foote, professor of pathology, College of Medicine, Creighton 
University, Omaha, Nebr. On this piece of hemstitched linen the 
tissues, cells, and crystals are embroidered in colored silks represent- 
ing the hematoxylin and eosin stains. The nuclei are in blue, the 
cytoplasm in pink, and the crystals in brown. These cells are ar- 
ranged around a large Purkinje cell of the cerebellum. The linen has 
a 14-inch frame, and is a very unique and interesting piece of work. 
A plaster bust and a marble medallion of Dr. Andrew Taylor Still, 
the founder of osteopathy, was contributed by Dr. George A. Still, 
surgeon in chief of the American School of Osteopathy Hospital, 
Kirksville, Mo., and are valuable additions to the exhibit which illus- 
trates the history and principles of osteopathy. 
The American Osteopathic Association of Orange, N. J., appointed 
a committee to cooperate with the Museum in obtaining material to 
complete the exhibit relating to this subject, and there has been re- 
ceived for this purpose by gift, through Dr. Norman C. Glover, the 
Washington representative of this committee, a small collection of 
books dealing with osteopathy, photographs, and an unmounted 
human spine. 
Old homeopathic medicine cases were contributed by Dr. Mary 
E. Hanks, Chicago, Il, and Dr. Lynn A. Martin, of Binghamton, 
N. Y., through Dr. W. A. Dewey, of Ann Arbor, Mich. The case 
presented by Doctor Hanks is made in the form of a book, and is 
very interesting. The case donated by Doctor Martin contains two- 
hundredth potencies and was used for many years by Dr. Titus L. 
Brown, a well-known homeopathic physician and instructor. 
The collections in the section of wood technology, were increased 
by a number of accessions of importance. To the office of works 
of the British Government, through Sir Lionel Earle and the Ameri- 
can ambassador to Great Britain, the Museum is indebted for the 
gift of a most interesting piece of oak timber. This is a large sec-
