Chapter 9 — Discussion and Conclusion
Tests of bursting warimono shells that were manufactured under various conditions were conducted on the ground, and the position of moving stars were analyzed by a photographic method. To make the analysis easy, ring star shells were employed as test shells. The results showed the quantitative relations among design factors, which were not clear until this study. These data were introduced into empirical equations concerning the ballistics of stars, which are useful for designing the chrysanthemum shell.

Chapter 8 — Examples of Designing Chrysanthemum shells
8.1 Comparison of Calculated and Experimental Values
The accuracy of the empirical equation for the initial velocity of a star was examined in Section 6.5.5. The accuracy of flight velocity can be examined by the probability deviations of the constant n' and log vo. Therefore, the author only compared the results obtained from the empirical equation with the results of experiment.

Chapter 6 — Formulae for Calculating the Velocity of Stars
First, the author studied the law of motion of stars in the air. The velocity of stars at distant points from the shell burst was then related to the initial velocity of each star. The conditions that produced these initial velocities were investigated, and from this information, equations useful in the designing of shells were developed.

Chapter 5 — Supplementary Experiments: Measurement of the Burn Velocity of Burst Charges and Stars in the Normal Atmosphere
To obtain these data, the 16-mm movie camera was used. A Black Powder pasted paper strip was arranged on a piece of metal mesh. Grains of burst charge, or stars, were arranged on the strip at intervals of about 5 cm, and the paper strip was ignited at one end. The grains or stars ignited one by one. They were photographed from a distance of about 1.5 meters.
