Figure 1. Left - A scale with U rings, the fourth close to the ed^-^e 

 and touching it at the base of the sculptured oortion. 



Right - A scale with \\, rings, the fourth well wj.thin the 

 edge. 



Owing to their large size, irregular surface, and fine structure of 

 the external folds, sardine scales do not photograph well. 



In reading scales, it is necessary to focus continually, and sor.ie- 

 times to alter the lighting in order to see all parts of all rings. The 

 following plates show one what can be seen at a particular focus and 

 lighting.
