Copied from tracing of profile furnished by C. J. Brydges, Manager, and reduced to 

 mean tide by connection with the special survey along Connecticut river, as previously 

 noticed (p. 251). This profile thus referred to sea level indicates for Gorham a 

 height 10 feet greater than that given for this railroad station by Guyot, from which 

 base his determinations of altitudes among the White Mountains were probably 

 computed. (See note beyond.)

Abbreviations. L., Spirit Level; P. L., Pocket Level; T., Trigonometrical; B., 

 Mercurial Barometer; A., Aneroid Barometer. After names of mountains, G. signifies 

 measurements made by Prof. Arnold Guyot, LL. D., of Princeton, N. J. ; J. those 

 taken by Dr. Charles T. Jackson, as published in his final report on the geology of 

 New Hampshire. Many of them have been calculated for the present chapter from the 

 observations printed in that volume. The trigonometrical measurements were made by 

 the United States Coast Survey, mostly under the direction of Prof. E. T. Quimby.
