For comparative purposes the constants of chaulmoogra oil 

 used in this experimental work and of other samples of chaul- 

 moogra oil that have been examined in the Bureau of Science are 

 inserted. 



DESCRIPTION OF SAMPLES OF CHAULMOOGRA OIL 



Sample 1. — This oil was obtained from the Philippine Health 

 Service from the stock used by them in the treatment of the 

 lepers at Culion. It was a greenish yellow limpid oil (30°C.) 

 with a characteristic odor. 



Sample 2. — This oil was extracted from seeds by means of 

 petroleum ether. The oil was liquid (30° C.) ; it was somewhat 

 lighter in color than sample 1, but had the same odor. The 

 seeds were obtained from H. G. Carter, economic botanist to 

 the Botanical Survey of India, Calcutta, India, and were labeled 

 "chaulmoogra seed — Taraktogenos kurzii." 



Sa.viple 3. — This is an oil purchased from the German Dis- 

 pensary, Manila. The oil was of the same color and odor as 

 sample 1, but differed from the preceding in that it had a small 

 quantity of solid particles deposited, about two parts per 

 hundred. 



Sample U. — This is a sample of oil purchased from the Botica 

 de Santa Cruz, Manila, and marked "Aceite de Chaulmugra." 

 The sample was practically identical with sample 1 in appearance 

 and other properties. 



Sample 5. — This sample was purchased from the Botica de 

 Santa Cruz. It bore the following on its label: 



"Chaulmoogra oil." The fixed oil expressed from the seeds of Gynocardia 

 odorata R. Brown natural order Bixaceae. Should the oil become solidified 

 from cold, it may be readily liquified by placing the container in warm water. 



Dose 10 to 20 minims (0.6 to 1.3 cc). Guaranteed under the Food and 

 Drugs Act, June 30, 1906, guaranty No. 6. 



This oil was so nearly solidified at the ordinary temperature 

 (30° C), that it would not readily pour. 



Sample 6. — This oil was submitted by the Philippine Health 

 Service for test to determine its purity. The sample was liquid 

 and possessed the odor and color of sample 1. 



Sample 7. — This oil was expressed from seeds purchased 

 through the Department of Agriculture, Assam, Seed Depot 

 Gauhati. They were marked "gynocardia odorata," but were 

 sold to the Bureau of Science in response to a request for chaul- 

 moogra seeds. The oil was a heavy, limpid oil, darker in color 

 than sample 1, but with the same characteristic odor. 



Sample 8. — This oil was submitted by the Philippine Health
