Lymphocytes from a patient with chronic lymphocytic leukaemia were found to contain crystalline inclusions in the cytoplasm. These crystals were characterised as IgMlambda immunoglobulin. The cells did not have detectable surface immunoglobulin. No paraprotein was detected in the serum and no excess of immunoglobulin was detected in the urine. The cells incorporated radioactive leucine into mu and lambda chains during an 18-hour culture. Studies of labelled lysate immunoglobulin revealed a molar excess of heavy chain over light chain while in contrast free light chain was the only detectable secreted immunoglobulin product during the culture period. These findings are discussed in relation to immunoglobulin synthesis by normal and other neoplastic lymphocyte preparations.
Distant visceral metastases were found in 15 of 32 cases of pleural mesothelioma (47%). Contrary to earlier reports pleural mesothelioma should be regarded as a tumour in which visceral metastases are not uncommon. No association was found between the histological type of mesothelioma and visceral metastases; the peritoneal involvement found in five cases is probably due to local infiltration and seeding.

The exfoliative cytology of 14 diffuse mesothelioma (11 pleural and three peritoneal) is described. Malignant cells were identified in 10 patients; in eight malignant cells still retaining the characteristics of mesothelial cells were found. It is suggested that only if malignant cells of this type are recognized should the probable diagnosis of diffuse mesothelioma be made.
