are taken into account, the sum of his influence will 

 be seen to have been vast. " Among the pupils of 

 half a century," says Professor Caswell, " how many 

 have caught the enthusiasm of the master, and given 

 their energies to science, and placed their names high 

 on the list of its honored cultivators! How many 

 hundreds and thousands of those who in different 

 cities have listened to his eloquent lectures, have 

 learned to appreciate science, and gather refined 

 pleasure from its culture, and give to it their hearty

 institution of learning, in every profession, nay, in 

 every workshop, and every cultivated field, in this 

 broad land of ours ! " *
