The figures show an increasing transparency the further down the Firth 

 the observations are made, and they also show that as the water becomes 

 clearer seasonal variations have greater influence on the transparency. 



The northern Stations similarly arranged show the same characteristics :

The central waters are the clearest, angl these round the Fife coast are 

 more transparent than those round the shores of the Lothians. 



If the fishing returns were compared with these figures some interesting 

 results might be expected. 



The observations made at the Stations in St Andrews Bay have been 

 tabulated in the same way as those of the Firth ol Forth. The mean 

 transparencies for each half-year and for the year, and the maximum and 

 minimum readings during the summer and winter six months of 1892, are 

 given below : —
