680 Mr, Ludwig Mond on Metallic Carhonyls. [June 3, 



you how lie himself elaborated this idea, and how it developed, until 

 within recent years it has led to results of the highest scientific 

 importance, and probably of great practical utility. 



Had Liebig all these results before his " mind's eye " when he 

 penned those prophetic words I have quoted? This is a question 

 it is impossible to answer. Who will attempt to measure the range 

 of vision of our great men, who from their lofty pinnacle see with 

 eagle eye far into the Land of Science, and reveal to us wonderful 

 sights which we can only realise after toiling slowly along the road 

 they have indicated ? Whether Liebig saw all these results or not, 

 it is due to him, and to men like him, that science continues its 

 marvellous advance, dispersing the darkness around us, and ever 

 adding to the scope and exactness of our knowledge, that mighty 

 power for promoting the progress and enhancing the happiness of 

 humanity.
