### Dimensional Changes--Wood Deformation Produced by Solvents  
As a result of the experiment, it is evident that there are changes in the flatness of the samples. The deformation could be observed visually and was also determined using a dial gauge and digital depth gauge measurements. The values obtained for the three solvents used in the experiment, for both thin and thick samples, can be seen in Tables 6-8. \begin{table}
