it at the miiseum and made it available for study. The Lapland 

 trip M^as to Abisco, arriving on July 18, about a week too late to see 

 the full midnight sun, but there was no darkness and the sun was 

 visible for twenty-three hours of the day. The Laps were all living 

 in the same primitive fashion, but some of them were well-to-do from 

 the profits of their reindeer herds. After a few days in Copenhagen 

 and Berlin about a week was spent at the Riks Herbarium at Leiden, 

 Holland, where may be found the herbarium of Persoon, one of the 

 greatest pioneers in the study of fungi. After several days study at 

 the Herbarium of the University of Paris, at the Jardin des Plantes, 

 where one is constantly reminded of the great Lamarck, Kew was 

 again visited for two weeks, and the trip ended. 



252nd Meeting — December 13, 1921 



A. S. Wheeler — Research in Progress in Organic Chemistry at the 



University of North Carolina. 



A study is being made with Mr. I. V. Giles of the action of 

 chlorine upon 2-amino-p-cymene. The constitution of the monochloro- 

 derivative has been determined and a series of new dyes has been 

 prepared by coupling it up with hydroxy compounds in the benzene 

 and naphthalene groups. These dyes are browns and yellows, espe- 

 cially adapted to wool. The problem given to Mr, S. C. Smith is 

 the constitution of the N,N', f3, R. /3 -Dichloro-hydroxyethylidene-bis- 

 nitranilines, discovered some years ago by Dr. "Wheeler. Mr. H. M. 

 Taylor is engaged in determining the constitution of bromo-2-amino- 

 p-cymene and will seek to prepare new dyes with it. Mr. F. P. 

 Brooks is studying the complex reaction between phenylsemicarbazine 

 and acetonylacetone, a diketone. The solution of the constitution of 

 Oxyjuglone is in the care of Mr. A. P. Sledd. This substance was 

 discovered 35 years ago. Mr. B. Naiman is studying the behavior 

 of monobromo-5-hydroxy-l,4-naphthoquinone. Mr. T. P. Dawson's 

 work concerned the addition and condensation products of chloral 

 with 3-nitro-4-toluidine. To Mr. C. K. Brooks was given the prob- 

 lem of the constitution of monobromoamino-p-xylene. Dr. Wheeler 

 is working in his own laboratory upon the reaction between phenyl- 

 semicarbazine and acetylacetone, having a grant from the Graduate 

 School to pay the cost of the raw materials.
