On the whole, therefore, I am left in a state of uncertainty as to the 
fact of valvular disease. 
Two things I have neglected to mention. 1. These sensations are 
about the same as are produced by a sudden shock—as when a window 
falls, ora door slams, or some person suddenly starts up before one. 
This would affiliate them to nervous affections. 2. Occasionally, lately, 
when lying quietly in bed, listening to the sound of the heart, I have 
fancied that the “deep” sound produced by the closing of the mitral 
valves is not as sharp as it used to be—but somewhat softened and pro- 
longed. This is as I believe it should be if there isan imperfect closure 
of these valves, and some of the blood reguryitates into the auricle. 
But if this is the constant mode of action Iam sure some impression 
should be made on my respiration, which I have not yet detected. I 
breathe as long as ever, and I am no more inclined to pant than ever. 
In hypertrophy of the heart, the ventricles, from over nutrition, lose 
the requisite capacity; but so far as I can see this would result only in a 
more sluggish circulation of the blood, producing a sense of faintness. 
and suffocation—instead of ¢rregularity in the pulse. 
1866. He applied himself, notwithstanding these solemn pre- 
monitions, and perhaps partly through the sense of the brevity 
of his remaining years, to his duties and to all his plans, with 
great diligence and effectiveness. In 1866 he published, in con- 
nection with Prof. Oliver Marcy, who supplied most of the speci- 
mens, ‘‘An enumeration of fossils in the Niagara limestone, col- 
lected at Chicago, Ll. ,”’ with two lithographic plates of illustrations 
drawn by himself. This contained descriptions of numerous new 
species. He made this year an economic survey of the Grand 
Traverse region, on which he published an octavo report of 82 
pages, witha map. In an appendix of 20 pages were embraced 
descriptions of a considerable number of new species of fossils, 
This report first brought to notice the remarkable influence of 
lake Michigan upon the climate of the region, and the wonderful 
capacity of the latter for agricultural and horticultural produc- 
tion. The statements of the report aroused the incredulity of 
some of the state officials, and an independent survey was made 
which fully confirmed the report. He read before the American 
Association at Buffalo, a paper on the Pruit-bearing belt of Mich- 
‘gan, in which, as in the report, he brought statistics toexemplify 
the hitherto unexpected influence of lake Michigan in ameliorat- 
ing the winter climate of the state of Michigan and prolonging 
the growing period. He read at the same meeting a paper on 
Stromatoporide, in which he described two remarkable new genera 
of fossils, and established a new family,
