Although written in Spanish, this book should have an appeal to anyone interested in the history of immunization to whooping cough. The author has made an exhaustive study of the steps leading up to the present methods. These methods are well discussed in painstaking detail. There is an excellent bibliography from all sources and mention is made of almost every source in the discussion.
This is as good a résumé of the subject of whooping cough immunization as the reviewer has seen, and it well earns a place in the literature of this subject.
