Notes:
The purpose of this study was to determine the dimensions of capilaries in various tissues, in vivo, in frogs, mice, and pups. Capillaries were measured in the web, strap muscles of the neck, mesentery and bladder of frogs, and in the mesentery of mice and pups. The light source was a fused quartz rod transilumination apparatus. In all cases the exposed tissues were kept moist by a continuous flow of Ringer's solution over their surfaces.The mean values found for the tissues of the frog are web 11.94 μ, skeletal muscle 11.30 μ, mesentery 11.97 μ, and bladder 11.40 μ. The mesenteric capillaries of the mice and pups had a mean value of 4.64 μand 7.36 μ respectively.Difficulties encountered during the course of observation included vibrations of the optical equipment, movement of the tissue under the microscope, fogging of the objective lens, and the determining of which of the microscopic vessels were “capillaries.”A statistical analysis of the data indicates that the variance in the measurements recorded on the capillaries of a single animal is greater than the variance from animal to animal.
