Instrumentation for the measurement of turbulence. What has been 

 learned about the structure of turbulence from experiment has depended 

 largely on the instruments available for making observations and meas- 

 urements. Here the hot wire anemometer has played a predominantly 

 important role. The number and accuracy of quantities measured have 

 gone hand in hand with the development of hot wire probes and the 

 adaptation of electronic circuits to amplify the signal, compensate for 

 thermal lag of the hot wire, and perform a variety of operations such 

 as adding, multiplying, and differentiating signals. The following refer- 

 ences therefore pertain mainly to the hot wire and its auxiliary equipment.
