Mr. Arthur Winslow has published a list of errata and 
acknowledgements for his report on the "Lead and Zinc De- 
posits of Missouri" (Mo. Geol. Survey, vols. 6 and 7). This 
list was not inserted in the report and Mr. Winslow will be 
glad to send a copy of the list to any one receiving the report 
who will apply to him. His address is: Rooms 411 and 412, 
Eoe Building, St. Louis, Mo. 
The Michigan Mining School has recently issued a " Pros- 
pectus of elective studies," which states that the school will 
this fall adopt an elective system. Students are allowed to 
select one of several courses with a certain principal subject, 
and in each course certain studies are required and the rest 
are elective. The school thus allows greater freedom in the 
selection of studies than do most mining schools.
