An apparatus is described which uses the principle of the ballistic pendulum to measure the tensile strength of blood clots formed in special cuvettes. The method appears to have a reproducibility which would allow a study to be made of the factors influencing clot strength. A brief survey of the findings with normal blood and with blood from cases of(More)
