| Description | Is enclosing Miles' note - asks for confirmation that colloidal iron is injected suspended in distilled water - Stehbens is to inject some into rabbit - interesting if Miles could take one of patches in which colloid iron has settled after histamine or protease injection, develop and fix it, and clear it as a whole mount - comments on this and on his feeling that the rather uniform bluish colour may not be entirely confined to the vessels - specimens have been embedded - hopes to get some sections cut within a few days. |
