104 REPORT OF NATIONAL MUSEUM, 1921. 



9 medicinal substances from the animal kingdom were presented by 

 McKesson & Bobbins (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, etc. 



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 

 tJniversity, 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 cerebellimi. The linen has 

 a l|-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, 111., 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-
