425&#93; FIL tion, the use of volatile salts, and other cephalics, is generally iusnf- ficient. Hence the tintSture of va- lerian, with vitriolic aether, may with more advantage be resorted to, both externally and internally. Relief has, in some instances, been derived from the compound tinc- tures of castor and of asafoetida ; but, if these various remedies prove ineffectual, the feet should be bath- ed in warm water, a fcEtid clys- ter be administered, and recourse had to electricity, A draught of vinegar or warm water, has occa- sionally procured ease j but, in very violent cases, opium only, under proper medical guidance, is capable of suppressing the pain. — Lastly, a new and eificacious cure for thfe face-ach, has been discover- ed by Dr. Haighton : — He di- re£ts the nerve proceeding from the infra-orbital hole, to be divided ; but this operation ought to be per- formed by a skilful surgeon ; as, otherwise, irreparable injury might be committed on the eye, or con- tiguous tender parts. With a view to prevent a return of this malady, the patient should undergo a course of totiic medi- cines, namely : take a copious draught of spring-water, early in the morning ; repair to the tepid, or, if his strength admit, to the shower-bath j and use the Peru- vian bark. FILM, in farriery, is a thick pellicle or skin, that is forn)cd on the eyes of horses; in consequence of which their sight is impaired. In order to disperse the film, it has been recommended to reduce common salt and sugar of iead, to a fine powder, and put a litile into the eye, so as to corrode the film. Another remedy consists in apply- ing a small quantity of fiuely pul- FOO [225 vfTiTfd sal ammoniac daily to the part atte6ted, till the obstruftioa be removed. FLEA- LOCUST, or Frog- HOPPKR, Cicada, L. Is a genus of inse6ts, comprehending 5 1 species, which are named chietiy from the trees they infest. Their beak is infieCled, and the animals are pro- vided with four wings. The larvae of several species of the Frog-hopper discharge consi- derable quantities of frothy matter on the branches or leaves of those trees, on which they reside. This froth has been supposed, by natu- ralists, to be ejedted with a view to secure these depredators agairist other inse6ts, or to shelter then^ from the heat of the sun. Such excrement, however, presents a very disagreeable appearance 3 and, as those vermin are highly detri- mental to trees, by devouring tlie leaves, Mr. Forsyth directs them, to be destroyed, by rubbing olr' the larvae with the hand ; after which the tree should be profusely washed with soft water. FOOD OF PLANTS.— Li a select collection of " Memoirs," lately published by the Free Society of Agriculture, Arts and Com- merce, in the Department ofAr- denne, the following vegetative liquor is recommended for promot- ing the growth, as well as the flowering, of bulbous rootsin apart- ments, during the winter, — Take 3 oz. of nitre 5 1 oz. of sea-salt ; half an oz. of salt of tartar; half a:i oz. of sugar ; and one pint of rain-water. Let the salts be gra- dually dissolved in a glazed earthen vessel ; and, when the solution is completed, add the sugar, and fil-^ terthcwhole. About eight drops of this Uquidmust be poured into every flower-glass filled with rain or river water ;
