Dr dorkarly Test Report - December 9th, 1918. Test No. 1 - Long tube samples of the Standard Dhemical Company. Readings: Luma 5 - 32 Cm. 11 6 - 30 Cm. 11 7 - 27.5Cm. 11 8 - 29 Cm. RLM NO. 5 - 22 Cm. RLM NO. ? - 23 Cm. RLM NO. 9 - 24.76m. RLM. NO.11 - 26.20m. The last samples received from the Standard Chemical Company, November 8, 1918, are graded according to letters A B C and D. The samples of this test are graded according to numbers. It would help greatly if the corresponding letters and numbers used by the Standard Chemcial Company could be obtained. Test No. 2 - Coarse and fine samples of material made September 9,1918. Readings taken December 9th, 1918. No. 5 - Coarse - 21.7 Cm. No. 5 - Fine - 2.2 Cm. No. 7 - " - 24.5 Cm. No. 7 " - - 25 Cm. No.10 - " - 28.7 Cm. No.10 - 11 - 29 Cm. No.15 - " - 32.5 Cm. No.15 - " - 32.7 Cm. No.20- 11 - 39.5 Cm. No.20 - : - 39 Cm. No.30 a " - 51.6 Cm. No.30 11 - - 51 Cm. The coarse and fine material are now reading practically the same. The coarse material has gradually grown stronger. Test No. 3 - Readings taken December 9th, 1918. No. 5 - 16.5 Cm. No. 49 - 47 Cm. No. 7 - 18.5 Cm. No. 69 - 62 Cm. No.10 - 24 Cm. No. 89 a 71.5 Cm. No.15 - 26.5 Cm. No.109 - 82 Cm. No.29 - 36 Cm. No.120 - 37 Cm. No.39 - 41.5 Cm. No.209 -108 Cm. material This yest was made November 2nd and there seems to have been no real change since the first readings were taken. -2- Test No. 4 - - Samples of the Standard Chemical Company received November 18th, 1918. Readings taken December 5th, 1918. Luma D - - 18.7 Cm. " B - 22.5 Cm. " A - 30 Cm. The large jump from B to A occurs in all readings of this material taken so far. It may also be detected by the eye with the aid of the machine. Test No. 5 - Readings taken December 5th, 1918. Material received from Cold Light Company, November 30th, 1918. No. 13 - 32.7 Cm. No. 7 - 55 Cm. No. 11 - 36.5 Cm. No. 5 - 58 Cm. No. 9 - 48.5 Cm. No. 4 - 63 Cm. A special test of the application material #10 was carried out. A sample of this material of the same age and quality as that being tested in our test No. 3 was applied in regard to determine the drop in luminousity caused by the paste. This material read 24 Cm. before being applied. After the application, it read 48 or 52 Cm. according to the kind of paste which was used. One sample was applied with a special paste made as follows: about 75 CC of Rosemarie oil was added to 300 CC of texine. In this mixture, special clear Demar gum was desolved until the proper paste was obtained. This paste when applied gave a reading of 48 Cm. Paste No.31 gave a reading of 52 Cm. Had material used been of a lower grade, the difference caused by the paste would have been greater.
