SEED AND POLLEN SENSITIVITY
It seems evident from the recent studies of Farmer1 that there is an organ-specific difference in plants from the point of view of allergic properties. He found that patients who were highly sensitive to aqueous extract of timothy, orchard grass or rye pollen often show no trace of cutaneous sensitivity with the aqueous extracts of the homologous seeds. Although at least half of the chromosomes are apparently identical in both pollen and seeds of the same plant, these observations suggest a complete divergence in protein specificity. Although Farmer has not formulated any biologic or chemical theory to account for this phenomenon, the observations are already of some practical clinical importance.
THE SEDIMENTATION RATE IN RHEUMATIC INFECTION
The urgent need for a reliable clinical method for determining the presence and degree of rheumatic infection in patients, particularly children, is generally recognized. As there is an increased
