standard cases, and for which specimen, case and general labels have 

 been prepared. There has also been removed from temporary exhibi- 

 tion all Amburayan Igorot material, which is also being prepared for 

 permanent installation. Labels for this group are being prepared. 

 The temporary exhibition of printing and engraving in the Newberry 

 Library has been greatly strengthened by material loaned from the 

 Mrs. T. B. Blackstone collection. Since the employment of an 

 assistant, whose time has been devoted primarily to the reparing of 

 broken and injured material, over four hundred specimens, which 

 include many valuable objects in clay, ivory, jade, porcelain, metal 

 and wood, have been prepared for exhibition. Owing to the steadily 

 increasing area occupied by installed material and material now ready 

 to be installed, it seems as though it would be necessary to make 

 provisions for the relocating of physical anthropology material now 

 stored in Hall 53, and the removal and caring for the vast amount 

 of material stored in double Hall 46-47. These halls will have to 

 be soon devoted to the exhibition of the Joseph N. Field collections 

 and similar material. In the Department of Botany little new 

 material has been received during the past year to augment the 

 economic installations, although considerable reinstallation has been 

 accomplished to render the exhibits more complete, educational and 

 attractive to the public. The new material inserted has come mainly 

 from the Section of Modelling. The following reproductions and 

 models have been installed during the year: To the Calla Family 

 (Araceae) has been added a full size plant of Anthurium acaule in situ 

 upon a tree limb. This reproduction shows the root system exemplify- 

 ing an aerophyte; several full-size leaves and one as yet unexpanded; 

 three flower clusters; one with the bract unfolded, one with the 

 ovaries unfertilized, and one heavy with developing fruits;, and a full 

 ripe fruiting spadix depending with its weight. Associated with this 

 are a male and female inflorescence of the Jack-in-the-Pulpit {Ariscema 

 triphyllum) , cut open to show the flowers at the base of the spadix, 

 and a highly enlarged male and female element. The Lily Family 

 (Liliaceae) has been further illustrated by additional economic 

 material and a model of a complete plant of the Aloe (Aloe vera) in full 

 flower. The Papaw Family {Caricacece) has been augmented by a 

 reproduction of a complete tree-top of the Papaw (Carica Papaya), 

 bearing three fully expanded leaves, each about two feet in diameter; 

 a number of leaf stems; a complete female inflorescence with three 

 developed and many undeveloped flowers and twelve fruits grading 

 from a young expanding ovary to a full ripe papaw. With this is 

 associated a complete male inflorescence, wrought in glass, bearing
