IMay Start Optical Work Soon
On New Lens 'For Observatory
Optical work on the 27-inch lei~s for
the large refracting telescope -Whose,
mechanical pa:rts are now under con-
-truiction at the University observatory
shophs, may be started in the near.fut-;
j ture if the 18-inch rough :glass disk
recently cast for the purpose in Sena,,
Germany, and shipped to this country
last. February, passes final inspection.
No notice of the arrival of the disk:
has been received, however, from the
,John A. Brashear company, Pittsburg,
where the optical work will be done,
and it is expected that the delivery
may be delayed dure to present trans-
itlantic freighting conditions. Thg' ac-
tuAl work on the lens will take consid-
arable time; similar work on a 40-inch
lens, the largest in existence, recently
F built for Yerkes observatory, took rive
year;,.
The telescope under construction
was donated by Robert' P. Lamont,
'91R It was designed under the su-
pervision of Prof. W. J. H-ussey, of the
astronomy departien t Negotiations
for the casting of the disk were under-
taken as early as .1911 with firrms in
Germany and France,, long .the oAnh'
production of~ these disks is 'extremely,
scarce, knowledge of -the ,craft being
tconfined to a single Swiss family in
which it is passed from father to son;
excepting in the. case of the. German
works where development of the in-
dustryha-been fostered by the gov-
ernment. Finallyt in 1918 after, the
close of the war, Schott 'and sons,
Jena, accepted the, contract.,,;
The Pittsbur fir'swhose optician,
J. ).' RC aW1, illfinish the lens,
isoe.of two in this country fitted,
for this work.' As soon' as Mr'. Mac-
Dowell's work is finished the lens will
be sent to Ann. Arbor, where the In-
strument will be assembled andl tried.
Though its permanent lecatlon is still
uncertain, states Professor Hussey, it
vantages over reflectors in certain
phases of astronomical work, difficulty
in casting homogeneous glass disks
of sufficient size hasa always ind-tered
their manufacture.
