title: [In vivo titration of tetanus antitoxins].
abstract: The theoretical background and the practical techniques of assay of tetanus antibodies on mice by the L+ toxine procedure, is precisely described in detail. Basing the arguments on certain aspects of the method, the accuracy of the test is estimated and its reproducibility is assessed, in terms of both in vivo and in vitro titrations.
