Problems of Filterable Viruses

    Article metrics


    THE frequency in recent years of viruses and virus diseases as subjects for discussion at international congresses testifies alike to the wide interest manifested in the biological problems that await solution and to the far-reaching economic importance of this type of infection in the animal and plant worlds. In NATTJBE of Oct. 10 appeared the main part of Dr. H. H. Dale's presidential address to Section I of the British Association. This address dealt strictly with the biological nature of viruses, an aspect of the general virus problem which, in spite of intensive research in many countries, is likely to offer for some considerable time yet abundant scope for speculation. Dr. Dale's careful analysis of the available information led him, on the whole, to favour as the best working hypothesis one which postulates that the viruses are independent living entities and not of the nature of intrinsic cell ferments or catalysts.
