Nurses, and very kind and obliging friends, usually attend so strictly to the above order in giving food and drink, that, though the poor patient be burning with thirst, he can only have permission to quench it at the fixed and assigned hours; and, through a feeling of pure benevolence towards the sick, they interrupt a salutary sleep rather than fail in punctually giving either drink, nutriment, or medicine at the corresponding hours. Under the influence of an amiable sense of duty, the anxious mother is often heard to assure the doctor that she herself was attentive to give her child its drink or medicine at exact time, as announced from the nearest church spire by the striking of the clock; though it grieved her to interrupt its gentle slumber. During the exacerbations of intermittent fevers, so prevalent in Peru, the state of the stomach is usually much disturbed; and in such circumstances, instead of alternating food and drink without regard to the condition of the digestive functions, we have taken pains to persuade the sick to deviate from the order established by custom, and allowed our patients the inexpressible comfort of drinking as often as thirst urged them, until there was obtained a solution of the febrile exacerbation. III. _Prepararse para tomar purga._—Many practitioners of the venerable Boerhaavian school have died in Lima in course of the last few years, but several of this stock are yet remaining; and, in their professional harangues at consultations, they are heard to talk learnedly of the malignant, adust, crude, and corrosive, &c. state of the humours of the human frame, without, as it always appeared to us, being able to affix any precise and practical ideas to these hypothetical expressions. And though the junior doctors of modernized opinions are generally found to indulge in some theory of the abstract solidists, yet they are obliged to respect the prejudices of the vulgar, and talk in a way that is agreeable to those whom it is their business to persuade. Patients, blinded by the received notions concerning the scorched blood, and displaced, corrupt, or perturbed and jumbled humours, reckon the daily visit of the physician indispensable under ordinary circumstances of indisposition. They do not expect that, day after day, active drugs are required; but, according to their own precognition of the case, they think it necessary for their safety that their medical adviser make his regular visits and observations, carefully examine the various excretions, and so be able to judge accurately of the character of the case, and prepare the patient by delay, diet, and diluents, &c. to take physic in due time, which is the meaning of the vernacular expression, “Prepararse para tomar purga.”
