[92] The form of administering this medicine was to add twenty drops of thebaic tincture, from half a grain to a grain of emetic tartar, and from five to ten grains of nitre, to two ounces of water or camphorated julep, of which one half was given about two hours before the common hour of rest, and the remainder at that hour. If spiritus Mindereri is preferred to the nitre, it may be given from two drachms to half an ounce for a dose, and it is better to administer it separately; for if it should not be exactly neutralized, it may decompose the antimonial, and render it inactive. [93] Since the publication of the first edition of this work, there has appeared a small tract on the treatment of low fevers, by Dr. Wall, of Oxford, and as his ingenuity and learning give him a just claim to the high rank he holds in his profession, attention is due to what he advances. The principal scope of the work is to recommend, from his own observation, the early use of opiates in those fevers, and the Doctor’s authority, as well as my own experience, convince me of the propriety of this practice in many cases occurring in this country, particularly among the lower sort of people, for whom spare diet and hard labour render evacuations less necessary than among the better sort. The inferior class of people are also more subject to this sort of fever from their houses and persons being less clean, and their apartments being worse ventilated; so that practice in these, as well as other cases, is to be varied according to the constitution and previous habits of life. [94] I first learned this, as well as many other useful and practical facts, from Mr. Farquhar, Surgeon in London, who has laid me under the greatest obligations by communicating many of his observations, derived from the most extensive experience and a truly penetrating sagacity. [95] I owe this piece of instruction, as well as many others, to Dr. Cullen’s Lectures. [96] In a review of Haslar hospital made in person by that excellent officer, Vice-admiral Barrington, in 1780, it was very judiciously proposed, among other salutary improvements, that there should be two apartments for the reception of the sick upon their first landing; one wherein they should be stripped of their dirty clothes, and another in which they should go into the warm bath, and put on the hospital dress, that they might not carry infection into the wards. [97] The following is the form of it, and it was first introduced by Mr. Whitfield, apothecary to the hospital, under the name of Bolus Sedativus:--℞. Confection. Damorat. [dram]ss. Castor. Russic. pulv. [scruple]ss. Tinct. Thebaic. g^{tt.} iv. Syr. sim. q.s. Fiat bolus sexta quaque hora sumendus.
