Gifts to the Chemical Library.

The Department of Chemistry has recently received from Mr. Edward Mallinckrodt, of St. Louis, the sum of $1,000, which has been used in refitting the library of Boylston Hall and in buying several hundred new books on chemical subjects. By means of this gift, the library has been almost completely remodeled and the capacity of the shelves more than doubled. E. Mallinckrodt, Jr., '00, has added to the gift of his father a sum, to be paid annually for the next five years, for use in paying the running expenses of the library. Many valuable chemical books have been added to the library by the gift of Dr. W. Gibbs h.'88, Rumford Professor Emeritus.

Owing to the large number of acquisitions received, it has been deemed advisable to keep the shelves open during the evening. A new assistant has been appointed, and hereafter, in addition to the daily hours from 9 until 5 o'clock, the library will be open at night from 7 to 10 o'clock.
