The human hand is a fascinating subject, an actor of many roles and disguises: the man in miniature, revealing its owner's story, here is a book which sets out to teach us how best to examine it and is disappointing because it is only 50 per cent of the classic it might have been.

In the revised criteria, patients with a high concentration of lupus erythematosus cells (as in Exclusion 2) are still to be excluded from the rheumatoid categories, but are to be listed separately and discussed simultaneously with r heumatoid patients if they satisfy the present criteria and exclusions in every respect.

Improvement following treatment in hospital was reasonably well maintained in the majority of patients if subsequent medical and social supervision were adequate and the most important factors in prognosis proved to be the duration of disease on admission, sex, and type of course run up to the time of admission.

The hope that the problems of long-term treatment of rheumatoid arthritis had been solved by the discovery of the remarkable therapeutic effects of cortisone and ACTH has not been fulfilled and it would appear that in only a relatively small proportion of patients can symptoms be satisfactorily controlled over a long period without side-effects or complications.

When the clinical picture of rheumatoid arthritis was defined by Garrod (1859) and practically the same syndrome was termed "rheumatisme articu- laire chronique progressif" by Charcot (1874), these terms were used to designate a chronic arthritis, progressing unfavourably and resulting in some degree of permanent disability.

Using a sensitive modification of the latex fixation test it is possible to detect a small agglutinating effect in about 60 per cent of normal human sera, after these have been heated for 30 minutes at 56°, caused by an IgM globulin with the properties of a rheumatoid factor.
