Temporary relief has also, in many cases, been obtained by the external application of volatiles and aromatics, as ammonia, camphor, oil of cajeput, and ether; and where the disease has been produced by cold or rheumatism, from blisters, burning moxa*, or the actual cautery t, an issue or a seton .

But we have stated that this form of the disease is often dependent upon some structural irritation within the cavity of the skull, such as a node or toph, or caries of the interior table of the cranium, a scirrhous or other tumour in some part of the brain, or a thickening of the membranes that surround it.

Hence, the Turks and Arabians make strong coffee their common vehicle for opium, from its tendency to counteract the narcotic principle of the latter *.
