The physiology of the circulation in plants : in the lower animals, and in man : being a course of lectures delivered at surgeons' hall to the president, fellows, etcof the Royal college of surgeons of Edinburgh, in the summer of 1872 .

Thecapillary syphon differs from the ordinary syphon in this, that the point at which the fluidescapes may be much higher than thartfat which it enters. Thus the fluid may enter at a, andescape at c, instead of at d. The instant the end of the syphon b is placed in fluid, the fluidrises and falls, and travels in the direction c, finally escaping at d. The compound capillarysyphon here figured is equally effective when inverted, the fluid being applied from aboveinstead of from beneath. The compound capillary syphon explains within certain limits thecirculation as it exists in plants with well-defined vessels and intervascular spaces.—Original. Fig. 39.—Simple and compound syphons perforated at various points; the perforationsbeing covered with animal or vegetable membrane, to prevent the ingress of air, while theydo not prevent the ingress or egress of fluids by absorption and evaporation. r, Sh
