Turin. The work of the latter place consists principally of aerodynamic studies.

The experiments and studies made at the Institute of Experimental Aeronautics are obtained by our military Attaché, translated, and forwarded to Washington. Many of the studies made there are very important, especially those made by Colonel Crocco. A photograph of their wind tunnel will be found in the photographic supplement. Description and designs of the principal instruments used in their aerodynamic experiments, which were reported by the Engineering Division of our Air Service, should be very valuable.

The Lighter-than-Air Constructing Establishment has carried out interesting experiments with dirigibles, observation balloons, free balloons, and parachutes. The Director gave us copies of reports on their most interesting studies and developments which have been translated and forwarded.

A copy in Italian of these standard test methods has been procured and
