According to the decisions of the Congregation of Rites chasubles must not be of linen, cotton or woollen stuffs, but of silk; though a mixture of wool (or linen and cotton) and silk is allowed if the silk completely cover the other material on the outer side; spun glass thread, as a substitute for gold or silver thread, is also forbidden, owing to the possible danger to the priest's health through broken fragments falling into the chalice.
An octroi duty of 9% ad valorem formerly levied on all food stuffs entering the city was abolished in 1903.
Drawers of cedar or chips of the wood are now employed to protect furs and woollen stuffs from injury by moths.
New industries are those of tapestry, brocades, imitation of ancient stuffs, cloth of silver and gold, and Venetian laces.
The only industries are carpetweaving and the manufacture of cotton and silk stuffs.
