The document outlines the courses and instructions for a department course on microscopical analysis. It lists courses in botany, pharmacognosy, and chemistry of natural products. The course outline covers topics like starch identification, fibers, cell types and contents. Instructions specify attendance requirements, lab coat and tools needed. Students must have complete lab notes and are not allowed to eat, drink or use phones without permission. The document lists tools needed like microscope, slides, covers, beakers and details the process of powder sample preparation and evaluation under the microscope.

C-Evaluation of small objects
This section will deal with :

9. A- Knowledge of Microscope

10. B- Preparation of Powder Sample
1-Add suitable amount of powder
2-Add few drops of mounting medium
3-Inlaid cover with 45
Clear slide without air
bubbles
Fixation of
Slide using
Glycerol.

11. 4- Evaluation of Small Objects
Eyepiece magnification power :12x
Objective magnification power :
10x ( low power) or 40x (high power)
Magnification power = 12 40 = 480 x
Magnification power= apparent length ̸ true length
