"The latter presently seemed aware of what he was doing, for he exclaimed, 'The usual symptoms, _eh, mon Professeur_; strongly marked, _n'est ce pas_? Act promptly and decisively, as you say sometimes. Let blood--let blood--_appliquez des sangsues_--ha, ha, ha! that's what we call bleeding, both general and local, ha, ha, ha! then come on with your cold applications: ice, ice, a mountain of ice piled round about the head! follow up with cathartics, refrigerant diaphoretics, after depleting blister!--say you not so?--blisters to the nape of the neck--blisters behind the ears--shave the scalp--I forgot that--shave the scalp--strange I had not thought of it,--and the hair. _Mon Professeur_, I know you will think me very foolish, but--save the hair--I shan't have another growth--save the hair. Where was I?--ah, the blisters--that will pretty nearly do for me--keep every thing quiet, very quiet--after a while, digitalis and nitre--digitalis and nitre, _mon Professeur_--have I not said my lesson well?' "Louis stood perfectly still, regarding the poor fellow with a mournful interest. As Dervilly paused, he took off his spectacles, and wiped his eyes. 'Ah, Monsieur Louis, you talk very eloquently about medical science, but I baffle you; I am sure of it. Call the class together--_Ah, Notre Dame de Pitie_--call the class together; _voila la clinique_. Thus being thus, it must necessarily be thus. That's a wise saying, _mon Professeur_. Call the class together; propound why of necessity you can do nothing? because of a necessity nothing can be done. Call the class together; be active--vigorously antiphlogistic; time is precious--the patient in danger. Purgatives--I doubt as to purgatives. What think you?' And Dervilly paused, and cast on Louis a look so naturally inquiring, that the latter replied, as it were, involuntarily, '_Moi aussi je doute._' And it was so; with all his genius, all his knowledge, all his experience, and all his skill, the great practitioner stood, while minute after minute was lost, apparently hesitating what to do. At last he called me into the other room. 'Is it not possible to find Mademoiselle de Coigny?' he inquired. "'I have no means of knowing where to seek her,' I replied. At the same time I remembered she was in the habit of visiting the house in which Dervilly first met her, and fortunately knew the street and number. "'Let her be sent for instantly,' said Louis. 'Do not go yourself; you may be of service here.' Accordingly I gave Stabb the direction, and instructed him to procure Mademoiselle de Coigny's address, if possible; but if he were unsuccessful in this, to communicate the fact of Dervilly's alarming illness, and beg that Mademoiselle might be immediately summoned.
