The Committee appointed December 16, 1887, to prepare 
the Magellanic Medal, reported that the same was now ready 
and delivered it to the President, who gave it to Prof. L. M.

“Prof. Haupt, it is a great gratification to me, both personally and offi- 
cially, to present to you the Magellanic Premium, which has been awarded 
by the American Philosophical Society for your essay on ‘The Physical 
Phenomena of Harbor Entrances, their Causes and Remedies.’ This essay 
treats of matters of great national importance, and your discussion of them 
will greatly tend to the improvement of the methods now in use for effect- 
ing the permanent removal of the obstacles in our harbors and rivers, 
which are so dangerous to navigation and are so full of risk to the lands and 
buildings along their shore-lines. A glance at the map of the United 
States will show the great number of our navigable rivers and the vast ex- 
tent of coast-lines, and their valuable and important harbor entrances. 
And it is therefore important that the money appropriated for their im- 
provement and enlargement shall be wisely and scientifically expended. 
I think your suggestions will be found very valuable in securing stability 
to all artificial structures that may be erected in our great waters for their 
protection and convenient use, and you are therefore entitled to be hon- 
ored as a public benefactor. The Magellanic Premium was established 
in the year 1786, and the records of the Society show that only six awards 
of the medal and one honorary pecuniary premium have been made within 
the century. Yours is therefore the seventh premium. It is thus shown 
that the terms under which the premium can be claimed are difficult to be
