Summary:

It has been shown by measurements previously taken of model balloons, that comparatively slight alterations in surface may have considerable effect upon the resistance of a body. Reference need only be made to the very striking results obtained by those tests as regards the resistance of a model balloon covered with fabric. The raised threads of the fabric having been scorched with flame, the resistance of the balloon more than doubled in value, contrary to any procedure hitherto observed, when the Reynolds symbol increased from 100000 to 250000.
