To the Editor:—
Your book notice on "Diseases of Children" edited by Paterson, appearing in The Journal of Dec. 13, 1947, page 1039, specifies that the authors discuss desensitization only for early hayfever and states that "nothing is said about hayfever caused by giant and dwarf ragweeds or about desensitization against this type."Since the volume was written by British physicians and presumably for British physicians it is not surprising that this aspect of hayfever is not discussed. The ragweeds generally do not exist in the British Isles, and in fact are of no practical consequence throughout Europe. It is for this reason that the only significant hayfever in Britain is that due to the pollens of grasses, and the authors should not be censured for failing to consider the other types.
