'^ The manufacturers of the "Sartorius", one of the best brands of ylang-ylang oil. 

 have refused to sell us any of their first-quality oil, and the analysis of number 24 

 was made from the second quality of the oil. sold in Manila as "essence of ylang-ylang 

 de Pablo Sartorius." We expect to be able to obtain the first-grade oil from European 

 sources, and hope to include this standard brand in our future work.
