Advancement of ScienceColorimetersis predicated upon research. There- Etc.fore, in the scheme of things scientific,precision optical instruments play an im-portant role, for they are the tools of modernresearch.

The facilities of the Bausch & Lomb OpticalCompany are committed to the production ofthese tools. B & L instruments have long been themeans of solving myriad problems related to the phys-ical welfare of mankind. The store of academic knowl-edge, too, has been measurably increased by these accessoriesto optical science, while in the great field of modern indus-try Science continually uses them to uncover ways andmeans of accomplishing hitherto unheard of things.

At the beginning of this New Year the Bausch &Lomb Optical Company pledges itself to new efforts toserve the needs of Science, but in so doing to adhere tothe old ideals of craftsmanship and the old principles ofhonesty and fair dealing- which have guided it duringthe past three quarters of a century.

The School of Medicine is an Integral Part of theUniversity and is in the Closest Affiliation withthe Johns Hopkins Hospital.

ADMISSIONCandidates for admission must be graduates of ap-

proved colleges or scientific schools with two years'instruction, including laboratory work, in chemistry,and one year each in physics and biology, togetherwith evidence of a reading knowledge of French andGerinan.Each class is limited to a maximum of 75 students,

meli and women being admitted on the same terms.Applicationis may be sent any time during the aca-demic year but not later than June 15th.

If vacancies occur, students from other institu-tions desiring advanced standing may be admittedto the second or third year provided they fulfill therequirements and present exceptional qualifications.

TUITIONThe charge for tuition is $400 per annum, payable

in two installments. There are no extra fees ex-cept for certain expensive supplies, and laboratorybreakage.

Inquiries should be addressed to theExecutive Secretary of the School of Medicine, Johns

Hopkins University, Washington andMonument Sts., Baltimore, Md.

Graduates in Medicine who satisfy the require-ments of the heads of the departments in which theydesire to work are accepted as students for a periodnot less than three quarters. Tuition charge is $50a quqarter.

Tberesa Seessel Research FellowshipsTo promote original research in biological

studiesYALE UNIVERSITY

Two fellowships, yielding an income of $1,500 each.Preference is given to candidates who have alreadyobtained their Doctorate, and have demonstrated bytheir work fitness to carry on successfuilly originalresearch of a high order. The holder must residein New Haven duiring the college year, October toJune. Applications shouild be made to the Dean ofthe Graduate School, New Haven, Conn., beforeMarch 1, 1928; they should be accompanied by re-prints of scientific publientions, letters of recom-mendation, nnd a statement of the particular problemwhich the candidate expects to Investigate.

TIMEis the chief factor in most activities.
