DACHNOWSKI: BOG VEGETATION AND PEAT SOILS 55 
The water from peat soils is relatively clear; in several places 
of the state it is used occasionally for drinking purposes. The 
suspended particles impart to it a tinge of color from olive green 
to brown. Analyses of samples of bog water and bog lake water 
give the following results:

The osmotic pressure of these solutions is the same as that of 
Ohio lakes, the average lowering of the freezing point varying 
between 0°.005 and 0°.o10 when compared with that of distilled 
water. The acidity of the solutions varies from less than 0.00075 
to 0.004 normal acid when titrated with an 0.05 NaOH solution 
and phenolphthalein.* 
The several analyses submitted do not reveal the obvious 
distinction between successions of vegetation on peat soils and the 
changes in the chemical character of the peat. The fact that 
certain plant associations have an absolutely defined morphological 
and topographic distinction, and the fact that these contrasts must 
be attributed to conditions prevailing in the soil, directs special 
attention to the contrasts between peat soils of the various vegeta- 
tion units or groups of plants. The following series in TABLE IV 
is especially suggestive in showing the more typical features of 
the correlation.
