the country generally.” We certainly hope to see this work soon 
commenced. 
MisceLLaneous.—Among the operations in Maine are reported 
some measurements of heights by nearly all practicable modes. 
From these and other operations there, we see evidently looming 
forth “important data for the coefficient of refraction under dif- 
ferent circumstances, and in relation to the relative advantages in 
accuracy, time and other particulars of the different modes 0 
measuring heights.”—-At East Base near Galveston, an elaborate 
set of latitude and magnetic observations is reported.— The list of 
Coast Survey nautical discoveries and developments for the year 
embraces nineteen items, chiefly of shoals, rocks, banks and chau- 
ges in bars, inlets and harbors. The Gulf Stream submarine hill- 
The subject of adapting engraving to transfer printing is touched 
upon and is of much importance to such as are about using the 
ous devices tried.—Appendix No. 35, gives the results of two 
analyses of deposits taken from the boiler of the steamer Hetzel. 
This is a subject of practical importance. and it is to be hope 
that some corrective may grow out of such analyses.— Appendix 
No. 43 will be interesting to those who feel how great a loss the 
country sustained in the death of Sears C. Walker. 
There is much more in the various field and office operations, 
which might interest scientific readers, but space bids us refrain. 
In conclusion, we may remark, that taken as a whole, this report 
equals or exceeds any of its predecessors in the extent and value 
of its contributions to science; and that by its paper, typography, 
indexes and sketches, it goes far towards reasserting the admissa- 
bility of a Congressional Document to respectable libraries.
