DEATH OF FISHES IN THE BAY OF FUNDY. 
BY A. LEITH ADAMS, M.D. 

Awone all the fluctuations of opinion respecting the nature 
of the causes to which the phenomena of the physical sci- 
ences are referrible, none in so short a period of time have 
undergone greater changes than we see represented in the 
history and progress of Geology. The first observers, more 
| “engaged in the discovery of appearances than in seeking to 
divine their causes, were led, by the wonderful but imperfect 
Scenes constantly opening out before them, to infer, that the 
mysterious and extraordinary assemblages of strata and 
n organic remains therein imbedded were owing to causes in 
: sg way distinct, both in kind and degree, from the laws 
Which now govern the material universe. But the gigantic 
strides made in this science during the last half century have 
induced philosophers to conclude that throughout the ‘vast 
periods of time of which geology takes cognizance, there 
has ria been any intervention to the working of fixed and 
variable laws of change. The elevation of land, distortion 
: ey dislocation of rocks, together with their assemblages of 
ganic remains, were considered by the early obse
