OBSERVATIONS ON LACORDAIRE. 151 



When the rapidly advancing progress of science shall call 

 for another " Genera des Coleopteres" it will never be 

 accomplished again by any one individual. Entomologists 

 may therefore congratulate themselves that, before* the task 

 became too great, one man has been found who is worthily 

 and successfully carrying to a conclusion a work which will 

 ever remain a monument of perseverance and sagacity.
