We repeated the original experiments, but could not confirm the observation; furthermore, we could not transfer homograft sensitivity passively with extracts of sonicated sensitised lymphoid tissue from different sites (spleen or pooled lymph-nodes or draining lymph-nodes), or with extracts of lymphoid tissue of mice sensitised with grafts from several strains. In our hands, extracts of sonicated sensitised lymphoid tissue invariably failed to produce accelerated graft rejection. %U https://www.microbiologyresearch.org/content/journal/jmm/10.1099/00222615-2-3-279
