Labels on the chest reveal it was created for travellers to tropic areas. White paper label with black type face reads, ' Burroughs, Wellcome & Co/ 'Tabloids'/ of compressed/Dover Powder/5 gr./ Pulv.

The word 'poison' is stamped over the label in red. The term tabloid' medicines in compressed and measured doses was invented by Sir Henry Wellcome as early as 1884. Dover powder's key ingredient opium led it to be used as a cure for cholera, diarrheoa and the common cold. The mixture is usually comprised of opium, ipecac. and potassium sulphate. It was commonly used through the 1960s.
