BLOOD coagulation and the clinical pathologist.

Confronted by the contents of this issue, the reader may be surprised, even dismayed, by the preponderance of papers on blood coagulation, and he may protest that the usual balance between the branches of pathology is also upset. (This will be rectified in future issues.) He may feel that the importance of this subject to him, as a clinical pathologist, is unlikely to justify the effort required to understand all the latest advances. The Editorial Board, in an attempt to encourage such an effort, has decided to include these words of editorial explanation.
