COLLEGE OF CIVIL ENGINEERING. 281
pressly manufactured for us by Reichert of Vienna ; and, as the result
of consultation with biologists, physicians, and sanitary engineers,
the balance of the equipment for the special purposes of this labora
tory has been made by Dr. Rohrbeck of Berlin. With these excep
tions the equipment contains apparatus specially manufactured by the
mechanician of the college.
10. A Photographic Laboratory for reproducing the appearance
of tested specimens, for the purposes of the lecture room, as aid in
topographical surveys, and for the distribution, to graduates and pur
chasers, of reprints of the great collection of progress photographs of
engineering structures owned by this college.
11. An Astronomical Laboratory near the main building, con
tains an astronomical transit by Troughton and Sims,
provided with
two collimators ; a sidereal clock ; a four-and-half inch Clark equato
rial ; two large altazimuths reading to seconds by levels and microme
ters ; and two three-and-three-eights inch zenith telescopes by Fauth,
but modified by the mechanician of the college, besides sextants,
chronographs, chronometers, etc.
The buildings of the College of Civil Engineering contains the Of
fices and Observatory of the U. S. Weather Bureau, being the central
office for the reception of climate and other data for the State of New
York, and for the dissemination of weather forecasts to the region
tributary to this centre.
The Museums of the College of Civil Engineering contain
the following collections : 1. The Muret collection of models in
descriptive geometry and stone cutting. 2. The DeLagrave general
and special models in topography ; geognosy, and engineering. 3.
The Schroeder models in descriptive geometry and stereotorny with
over fifty brass and silk transformable models made in this college
after the Oliver Models. 4. The M. Grand collection of bridge and
track details, roofs, trusses, and masonry, supplemented by similar
models by Schroeder and other makers. 5. A model railroad bridge
of twenty-five feet span, the scale being one-fourth the natural size,
and a numerous collection of models of track details. 6. The Digeon
collection of movable dams and working models in hydraulic engi
neering. 7. Working models of water wheels, turbines,
and other
water engines. 8. Several large collections of European and American
photographs of engineering works, during the process of construction,
and many other photographs, blue prints, models and diagrams. 9.
An extensive collection of instruments of precision, such as a Trough-
ton and Sims astronomical transit ; a universal instrument by the same
