THE CHEMICAL WORLD THIS WEEK as coagulants. Often lime, soda ash, or caustic soda is added beforehand to raise the pH value and stabilize the carbonate constituents. Potassium permanganate is utilized in a few cases to oxidize ferrous and manganous compounds to their insoluble forms. Chlorine-holding compounds or copper sulfate carriers are added to kill bacteria and algae. Used only once, water injected into closed systems -usually is not treated again. Sequestering agents, like sodium hexametaphosphate or tetraphosphate, are sometimes employed to prevent future formation of insoluble compounds and corrosion. If subsurface bacteria are found to exist in the oil of the well, compounds like chlorine bleaches and formaldehyde are added as bactericides. For open and closed systems much the same process occurs as for the original treatment of the water, dependent of course on what analysis reveals is necessary to deliver neutral water to the well. The bureau stresses the role of the chemical engineer in such an operation as being most necessary from the standpoint of getting the best recovery and conservation.

Each fellowship carries a stipend of $1500 as well as tuition and fees. The stipend has been increased $250 over last year. Stanolind fellowships are available to all qualified students, with selection of the fellows to be made by the respective schools in cooperation with Stanolind. The company makes no reservations whatever about patent rights or subsequent employment of the fellow in its organiza-

Education
Note · . ·
Rutgers University is offering a course in "Science for Teachers" to set forth the impact of t h e various sciences on the problems confronting society. Conservation is the broad problem the group discussed the first semester. Classes have been held b y a physicist, a geographer, a botanist, a chemist, and by members of the department of wildlife conservation and management.

C e n t r a l Scientific Offers G r a d u a t e Scholarships
for use
Central Scientific Co. will offer two scholarships for graduate study for the academic year 1953—54, to be awarded to university students majoring in the physical sciences and engineering. The scholarships, limited to citizens of the United States, will include a $1000 award to a student working for his master's degree and $1500 to a student at the doctor's level. The funds will be used to assist the graduate in meeting school expenses. Interested students should apply in writing not later than April 15 to the Scholarship Committee, Central Scientific Co., 1700 Irving Park Road, Chicago 13, 111. Letters must include personal data, school chosen for graduate study, courses contemplated, some description of the research problem on which the student is working, and a transcript of his college credits.
