39、ble TeachersUnit 4 Unforgettable Teachers1 It was more than fifteen years ago that I entered the laboratory of Professor Agassiz,and told him I had enrolled my name in the Scientific School as a student of natural history.He asked me a few questions about my object in coming,my antecedents generally

40、,the mode in which I afterwards proposed to use the knowledge I might acquire,and,finally,whether I wished to study any special branch.To the latter I replied that while I wished to be well grounded in all departments of zoology,I purposed to devote myself especially to insects.D R _ Text 1Take This

43、 seen.”Unit 4 Unforgettable TeachersUnit 4 Unforgettable TeachersD R _ Text 37 I was to keep the fish before me in a tin tray,and occasionally moisten the surface with alcohol from the jar,always taking care to replace the stopper tightly.Those were not the days of ground-glass stoppers and elegantl

44、y shaped exhibition jars;all the old students will recall the huge neckless glass bottles with their leaky,wax-besmeared corks,half eaten by insects,and begrimed with cellar dust.Entomology was a cleaner science than ichthyology,but the example of the Professor,who had unhesitatingly plunged to the

45、bottom of the jar to produce the fish,was infectious;and though this alcohol had a“very ancient and fishlike smell,”Unit 4 Unforgettable TeachersUnit 4 Unforgettable TeachersD R _ Text 4I really dared not show any aversion within these sacred precincts,and treated the alcohol as though it were pure

46、water.Still I was conscious of a passing feeling of disappointment,for gazing at a fish did not commend itself to an ardent entomologist.My friends at home,too,were annoyed when they discovered that no amount of eau-de-Cologne would drown the perfume which haunted me like a shadow.Unit 4 Unforgettab

48、 dashed the fluid over the fish as if to resuscitate the beast from a fainting fit,and looked with anxiety for a return of the normal sloppy appearance.This little excitement over,nothing was to be done but to return to a steadfast gaze at my mute companion.Half an hour passed an hour another hour;t
