Step 3. Matching Cuticle Scale
Previous  Top  Next

With the Cuticle Scale tab selected the possible values for the cuticle scale field of the search key on the surface of the hair are illustrated in the search key view.
The value of the Cuticle scale field is initially undefined, which will be shown by a thin dotted line as a border around the "Unknown" image.  To select another value, click with the mouse on the drawing or photograph.

For this tutorial assume that the observed hair has scale pattern that resembles an regular wave. In the image below this value has been selected by clicking on the drawing labelled "Regular Wave". Notice that :
1.The search summary has updated to show Regular Wave as the value for the scale pattern field of the search key.  
2.The number of species matching in the search summary has changed to show only those species that have a narrow medulla lattice and a regular wave scale pattern.  
3.The number of sub classes showing in the species explorer has updated to reflect the new values of the search key.  

As is shown in the image below there are now three species that match the current search key.  The next step is to define the Cross Section field to further narrow down the list of possibilities. Click on the Cross section tab to move to Step 4 of the tutorial.
