1.   Equally satisfactory results can be obtained using more orthodox treatments.

2.   For thin sections, best results are obtained if the stain is warmed.

3.   However, good results were obtained in the prototype circuit without any special precautions.

4.   Of course, more work is required to obtain smoother results, and this is an important consideration when doing calculations by hand.

5.   Remarkably similar results have been obtained by studies in the United Kingdom and other countries.

6.   The best results are obtained from watercolours, oils being less clean and controllable.

7.   Best results are obtained by starting the plants off in a warm greenhouse.
