NOTICES BIOGRAPHIQUES. — THOMAS SPENCER COBBOLD 171 



benefits upon man and his inferior fellow-creatures — ought to 

 be held in high esteem; but, apart from this purely utilitarian 

 view, there remains for the investigator the delight occasionned 

 by the in-rush of new scientific ideas. The average raind, being 

 either essentially commercial or ridiculously sentimental, as the 

 case may'be, is totally incapable of comprehending the motive 

 power that animâtes and guides the votary of science. The late 

 professor Faraday, a man wholly untinged by the ambitions of 

 wealth and power, once remarked to me that there were no people 

 so difTicult to instruct as those who were ignorant of their own 

 ignorance. It is just thèse very persons who, when placed in high 

 positions of social, political, or professional trust, most powerfully 

 contribute to check a nation's progress. There are too few genuine 

 workers at science in this conntry. As one of the rank and file, I 

 clam only to bave honestly contributed my mite. ï shculd like to 

 see a small army of helminthologists rise up and lay siège to the 

 fortresses at présent securely held by thousands of death-dealing 

 parasites. » 



Comme on le voit, ce passage, si court qu'il soit, montre les 

 idées élevées qui avaient toujours guidé Cobbold dans ses recher- 

 ches systématiques ou expérimentales. En dehors de ses collections, 

 il avait toujours en vue l'intérêt social de la question, comme le 

 prouvent ses études particulières sur les animaux domestiques. 



L'œuvre de Cobbold est considérable et l'influence qu'il a exercée 

 sur les générations d'auditeurs qui l'ont écouté a été profonde. La 

 médecine et l'art vétérinaire lui doivent beaucoup et lui auraient 

 dû probablement davantage, si la mort n'était venue enlever aussi 

 brusquement ce savant à la science et à sa famille.
