GLACIERS

If you've been reading the almost-daily news headlines reminding us of the melting glaciers on our planet, you'll be interested in these two Bullis books by John Tyndall:

Forms of Water in Clouds and Rivers, Ice and Glaciers

by John Tyndall  (1820-1893)

Published in New York, D. Appleton, 1874, c 1872

and

Hours of Exercise in the Alps

by John Tyndall (1820-1893)

Published in New York, D. Appleton, 1875

Tyndall was a 19th century physicist and professor of physics at the distinguished Royal Institute of Great Britain.  In addition to teaching, he did research and authored 18 books, 10 of which are in the Bullis Collection.

We urge you to stop by the Bullis Room and spend some time with these books. Both of them have numerous illustrations, and Hours of Exercise in the Alps has some very informative information on:

"Structure and Properties of Ice"

"Structure of Glaciers"

"Helmholtz on Ice and Glaciers"

"Observations of the Mer de Glace"

We'll have more on John Tyndall's books in our post next week.
