occupation of the hall thus became complete, twenty-nine years from 

 the date of its erection. 



One year later, Professor Cooke entered on his last undertaking 

 for the enlargement of his domain. He began to make plans and 

 solicit subscriptions for a section of the University Museum on Oxford 

 Street to be devoted to Mineralogy. His primary object was to ob- 

 tain more space for the exhibition of minerals, and a new laboratory 

 of Mineralogy ; but a secondary object was to remove this valuable 

 collection from a building which was not fireproof, and which was sub- 

 ject to the risks of chemical experimentation. His efforts were soon 

 crowned with success ; and in 1889-90 a section of the Museum de- 

 voted to Mineralogy, with a floor area of 13,200 feet, was finished at 

 a cost of $35,000. This area provided not only an exhibition room, 

 but a lecture room, laboratory, and store-rooms. The Mineral Cabinet 

 having been removed from Boylston Hall, it became possible to pro- 

 vide in that building a large laboratory for Organic Chemistry, and a 

 new lecture room seating five hundred students. These changes were 

 made at the cost of the Corporation in 1891, Professor Cooke actively 

 superintending them in all their details. 



When a man has started early in enthusiastic pursuit of a worthy 

 object, and has vigorously pursued it through all his active life, it is a 

 sincere satisfaction to all who have observed him, and particularly to 

 all who have been at any time his comrades or followers in the pur- 

 suit, to see him, before death comes, reach his goal. Professor Cooke 

 attained and gave this happiness. He himself saw his beloved science 

 taught in the only way he thought wise and effectual, and raised in 

 academic standing to an equal level with the oldest and most valued 

 subjects used in education. He saw large laboratories and lecture 

 rooms, which he had himself planned and built, filled with eager 

 students. And finally he saw the mineral collection, which had been his 

 care and delight for forty-four years, safely and handsomely established 

 in the principal University Museum. Few men see so many of their 

 objects attained, so many of their hopes fulfilled. He had other 

 sources of profound satisfaction, some of which have been already 

 pointed out to-night ; it was my part to describe his remarkable and 

 enduring administrative achievements as Erving Professor of Chem- 

 istry and Mineralogy in Harvard College.
