Letter from Arthur James Ewins, regarding a paper 'Experimental chemotherapy of typhus Anti-rickettsial action of p-sulphonamidobenzamidine and related compounds' by Christopher Howard Andrewes, Harold King and James Walker Sectional Committee: Physiology Still feels his comments on the paper are justified, but were mostly suggestions to be taken forward for future publications, as applying them to the current paper would be time consuming. Has no objection to publication of the paper in its present form. Still feels the detail of the experimental part could be condensed. Note by Archibald Vivian Hill requests publication now.
