ACTS of Parliament and Statutory Rules and Orders affecting the chemical industry are sufficiently numerous and complex to require documentation in a convenient and easily accessible form. That task has been undertaken by the Association of British Chemical Manufacturers, which in January 1931 published an index of such information. The third supplement, covering acts, rules and orders which have come to the notice of the Association during 1933 has recently been issued (Heifer, Cambridge; 6d. post free). New regulations regarding the packing and stowing of dangerous goods in ships have been made, and a revised edition of the summary of the principal regulations made under the Explosives Act has been issued. Reference is made to the Spirits Act, 1880, and the Still Licence Act, 1849. All plant capable of being used as a still is subject to licence, but exemptions are granted in respect of alkali works, coal gas, tar distillation, solvent recovery, chemical experiments, professional chemists, etc. Water stills of more than 1 gallon capacity require a licence; otherwise exemption may be granted on application. The supplementary index also refers, inter alia, to the Dyestuffs (Import Regulation) Act, the Import Duties Act, the Ottawa Agreements Act, the Poisons and Pharmacy Act, and the Safeguarding of Industries Act.
