1. and Glasgow) We have examined some 1,500 rheumatoid joint fluids and have found calcium pyrophosphate crystals in only one case. This was associated with generalized active polyarthritis in an otherwise well-controlled rheumatoid arthritic. In at least Heberdent Society 221 twenty rheumatoid subjects with radiologically calcified synovium, we have not found crystals.

3. A study of complement-fixing (CF) antibody in 45 rheumatoid patients and 45 ageand sex-matched controls showed that there was an inverse relationship between the titres of antibody to herpes simplex, measles, and mumps virus and the titre ofrheumatoid factor. The mean antibody titres were higher in the controls than in the rheumatoid patients. After removal of rheumatoid factor with heataggregated human gamma globulin, the mean CF antibody titre for rheumatoid patients equalled that for controls with mumps and became higher than that for controls with herpes simplex and measles;Stanford, C.F.;Ann. rheum.
