precipitate of p-toluenesulphonamide is formed with liberation of chlorine. The. solution 
thus becomes strongly irritating. Even under favourable circumstances, excluded from 
moisture and light, the dilute solution decomposes quickly, so that is was recommended 
never to use dilute solutions more than 24 hours after their preparation and to. temove 
from the vessels and other implements all traces of the old solution: ya the aid of.

Frankincense. The Journal of Commerce of 12th June 1918°) relates the following | 
out of a consular report on the trade of the Aden district: Some of the most important 
natural products of Aden are frankincense, myrrh and gum arabic. In 1916/17. the | 
market and the prices for these articles were quite satisfactory. Although the quantities 
put on the market were smaller than in the previous year, the total value rose. Aden 
is supplied with frankincense almost exclusively by the free, Somali. ports and the 
Arabian gold ports. This resin belongs to the chief kinds of resin of the local market. 
Most of it is exported to India. The quantities sent there in 1916/17. have not ‘been 
exceeded in any previous year. The exports to France have increased likewise, whereas 
those to Abyssinia dropped and nothing was exported to Egypt; which used to. take 
considerable quantities. This aromatic resin is chiefly used in the countries referred 
to in religious ceremonies and for disinfection. Nothing was exported to the United 
States. Myrrh comes next in importance. It is chiefly imported from the free Somali 
ports. In 1916/17 the largest quantities were exported to Egypt, India. and the United 
States, the last-named countries taking almost three times as much as in | the previous. 
years. It seems that a permanent trade is developing in ee direction.
