A growing interest in the field of metrical photography is indicated by the 
fact that Muybridge's classical pictures, taken in the 1880's, are being reprinted, 
“The Human Figure in Motion” (1956) 
1956) by Dover Publications, New York. 
and “Animal Locomotion’ (June, 
Any photograph when used for measurement, qualitatively and quanti- 
tatively, is a part of the science of photogrammetry.
