The diagnostic index of the Bristol Royal Hospital for Sick Children j^Pfded 197 cases of anaphylactoid purpura between 1952 and the end of k' and it has been possible to trace and analyse the notes of 191 of these, whom 62 had evidence of renal involvement. One of the children whose anH^ cou^ not be traced is known to have died from renal failure in 1962 inclusion of this case brings the incidence of renal involvement to 63 out 192 cases (33 per cent).
