YEL ciently full and accurate, to enable any person to distinguish that dis- ease from any other, except the malignant fever ; to which it has an obvious iitHnity. Where the yellow fever attacks in the manner of a common remittent, and shews no symptoms of malig- nity, till after somecontinuance. Dr. D. observes, that thefollowing treat- ment may not be deemed necessary or suitable ; though, he thinks it is, on the whole, tl)e safest plan, to consider every fever with which a new comer may be seized, as be- ing of this kind : for, unless the method of cure suited to it, be adopted in the beginning, it cannot afterwards be employed with any' probability of success. On a supposition, that a person newly arrived in Jamaica, or any other tropical country, be suddenly attacked with violent pain of the head and back, with heat and flushing of the face, Ike. in the manner before described. Dr. D. recommends, in the first place, to let the patient be put to bed, as soon as he is taken ill ; then an opening clyster lo be administered j and, immediately after, a dose olf calomel and jalap to be taken, ei- ther in powder, mixed with syrup of tamarinds, or made into pills. The dose must be regulated by the constitution of the patient, and the greater or less violence of the symp- toms ; so that from 5 to 10 grains of calomel, and from 15 to 30 grains of jalap, have been occa- sionally prescribed. Some time (from 2 to 3 hours) afterwards, a tea-cupful of tamarind-water, or a deco6tion of tamarinds with cream of tartar, should be drunk ; and, if stools do not freely follow, the pre- ceding, or a smaller dose, may be repeated iii the toarsc of 5 or t E L [3-7, hours. If plentiful evacuations have taken place, but without any abatement of symptoms, small •doses of calomel and antimonial powder should be given, in the proportion of from 5 to 10 grains of the former, to 3 or 5 grains of tlie latter ; to be taken every three hours in barley-water, or thin pa- nada. During the intervals, Dr. D. direfts the foMoviring saline ju- lep : Salt of wormwood, or salt of tartar, 2 drams, to be dissolved in half a jMnt of mlnt-t^a. To every tvi'o table-spoonfuls of this solu- tion, add one table-spoonful of strained lime-juice ; which mixture is to be Hwaljowed during its etfer- vescence, or immediately after. In order to ascertain the exa6t quan- tity of the acid requisite to neutra- lize the saline draught, it slwuld be t)-ied first, by pouring into the latter small portions of the former, till the frothing be completed. At the same time, the mercurial fric- tions must be commenced J namely, two drams of the strong mercurial ointment, rubbed into the inside of the knees or thighs, every six hours j or, in some cases, every three hours ; or, otherwise, half an ounce every six hours. If, in 12 or 15 hours from the first attack, there be xv) obvious remission, in consequence of such treatment, the friftions ought lo be continued every three ! hours ; and, if the bowels have not been opened, ten grains of calomel must be given in combination with jalap J or, in the contrary case, with one quarter of a grain of opjum> to prevent the calomel from afting on the bowels, if already too loose* Thin barley-water, or other dilu- ents, may be allowed frequently, and the medicines above specified be continued, till the mouth be- comes sore> and the breath afFeiSt- •Bb2 ed;
