dred miles long and two hundred miles wide, and delineated eleven different 
regions of rocks, made over three thousand barometrical observations, and 
tracked the characteristic species of rock of each basin to their source. These 
investigations were to have been recorded in the second volume of the ''Systeme 
Glaciaire" by Agassiz, Guyot, and Desor, but the breaking up of the University 
of Neufchatal (where Guyot was professor) by the Revolutionary movements of 
1848 prevented this project, and they were never published. A topographical 
map of the subaqueous basin of the lake of Neufchatel was prepared by him, the 
first of the kind ever published. 
He was Professor of History and Physical Geography in the Academy of 
Neufchatel from 1839 to 1848, when he left Europe and came over to America, 
soon after Agassiz, and by his persuasion took up his abode in Cambridge and 
drew immediate attention by a series of lectures deliveered in Boston in 1848-9, 
which Professor Felton translated for a newspaper. They were afterward pub- 
lished as a book, with the title " Earth and Man," which is still a popular work. 
Professor Guyot is best known in this country by his series of school geographies, 
which, appearing between 1866 and 1873, came into wide and general use in 
schools, and took rank at the head of geographic text-books. Guyot was elected 
Professor of Physical Geography at Princeton College in 1855, and subsequently 
Professor of Geology, and he has remained there ever since, being the senior 
professor of the College. He was the first to determine the true height of Mt. 
Washington in 1851, of the Black Mountains of North Carolina in 1856, and of 
the Green Mountains of Vermont in 1857. His contributions to science have 
been numerous and valuable. — Journal of Education. 
EDITORIAL NOTES. 
In view of the terrible floods in the Ohio 
River again this year, public attention is 
being given to devising means to prevent 
their re-occurrence. In this connection we 
invite a re-reading of the suggestions of 
Rev. Albert E. Wells, of this city, in his 
article upon "Freshets and Overflows" in 
the August, 1883, number of the Review. 
In the report on the Production of Swine 
in the United States, by Mr. Joseph Nimmo, 
a history of trichina is given, showing that 
it existed in Europe before the importation 
of American pork, and communications from 
the health officers of large cities, and other 
experts, are printed in support of the asser- 
tion that the danger arising from the con- 
sumption of pork is infinitesimal. In conclu- 
sion, tables are given showing the value of 
merchandise imported in this country from 
Germany and France, 
The German sanitary commission, which 
was sent out to Egypt by the imperial board 
of health to study the nature, causes, etc, 
of cholera, has discovered the cholera 
germ in a water tank at Calcutta, and 
found in the suburban village, where the 
cholera made its appearance, the same 
microscopic organism which has been dis- 
covered in the lower intestines of the cholera 
victims of Egypt.
