The present report is a description of 14 rhesus macaque (Macaca mulatta) births, five of which have been filmed in 16 mm colored silent film. All of the females shown in the film are feral, but descriptions of births in laboratory females are also included in the report. Time of delivery, observational techniques, signs of labor, differences with parity, and behaviors of both mothers and infants are included. A brief description of a few feet of film of a breech birth is also presented. The behaviors of adult males, who were sometimes present during delivery, are described.The characteristic labor posture is the squat, although some females crouch or lie down. Other birth behaviors are reaching back, licking, and stretching. Primiparous mothers generally have longer and more dficult deliveries and often appear to be nervous or clumsy shortly after the birth. The infant's behavior varies with its health; the present report describes the behavior of five infants. The behavior of adult males who witness births is variable, ranging from intense curiosity to aggression.

SummaryA series of di-, tri- and tetravalent axles and wheels for the synthesis of pseudorotaxanes bearing the tetralactam macrocycle/diamide axle binding motif was prepared. Starting from iodinated monovalent precursors, Sonogashira cross-coupling reactions were utilized to couple the binding sites to appropriate spacer groups. Through this “Lego” or “toolbox” approach, the convergent synthesis of host and guests with a well-defined number of the binding sites is possible. In addition, the spatial arrangement of the binding sites can be controlled through the quite rigid connections between linker and binding sites. Although a quantitative assessment of binding strengths was not possible by NMR titration experiments, typical and significant shifts of the signals of the diamide moiety indicate qualitatively the formation of pseudorotaxanes from the axle and wheel precursors.
