be as follows : mineralogy, lithology and dynamic geology, struc¬ 
tural geology, and historical geology. 
The first year’s course on mineralogy began on December 5, 
1898, and ended on April 15, 1899. This included one extra 
lecture which was given by special request at the end of the regular 
lessons and the final examination, making seventeen exercises, in 
all thirty-four hours of instruction instead of the required thirty 
hours. The entire number of applications received for this course 
was 145, and special provision was made to accommodate 130 of 
these. The unusual prevalence of sickness during the winter 
caused the loss of several from the class and a few also withdrew as 
they found the work more difficult than they could attend to in 
connection with the necessary work in their schools. The average 
attendance for the course was 106. Of these 72 took all the exam¬ 
inations, including the final. The instruction included one intro¬ 
ductory lecture upon chemistry, four upon ciystallography, and ten 
upon mineralogy proper. They were given by means of lectures, 
supplemented by a complete series of minerals illustrating the com¬ 
moner species, about 130 in number. Each two members of the 
class had one tray between them, containing all the species dis¬ 
cussed at any single lesson, and this enabled each member of the 
class to study with the specimens directly in hand. A complete 
set of notes was also supplied each member of the class, for which a 
cost price was charged. At each lesson except the first and the 
last the first half hour was devoted to an examination covering all 
the ground previously passed over, and at the end of the course a 
final examination of three hours was given which was so arranged 
as to present a concise resume of the whole subject. 
Dr. R. W. Greenleaf gave a course of fifteen lessons of two hours 
each upon the principles of the classification of flowering plants. 
One hundred species of native plants were collected, dried, mounted, 
and divided into sets by Miss E. B. Bryant, and each student was 
provided with one of these. Fresh material was also purchased 
when required for the use of the class. The class was especially 
indebted to Miss Helen Sharp, formerly an assistant in this course, 
for the use of her collection of water-color drawings of 901 sheets, 
774 of which represent American plants, the actual number of 
American species being 649. These drawings will shortly be 
assembled and exhibited in our laboratory, where they can be seen 
as a whole and properly inspected. This free public exhibition will
