The water was collected either by filling vessels from the surface, 
or in the case of the deep water by lowering atin bucket provided with 
proper valves. The much larger quantity of heavier mud brought 
up by the bucket proved that it acted properly. The water was 
collected in almost every instance under my own personal superinten- 
dence. 
The collection was made by means of an ordinary small boat 
or dinghy. The changes of position which could not be avoided 
account for the irregularities between the surface and deep waters, 
taking into account the strong currents and eddies that prevail. 
The table exhibits the great influence of the tides: taking the 
extreme case of 14th June after long drought, just two days before 
the rains commenced, we have in 100,000 fl. grains of water 151.9 gts, 
solid matter at high water, and 30.7 gr. at low water, or nearly 5 to 1; 
while comparing the Chlorine as Chloride of Sodium or common salt, 
the proportion is fully 8 to 1. These great differences occur chiefly at + 
spring tides. The results of 24th May shew how comparatively 
small this is at Neap tides, 19 grains of salt at nearly high water to 
12 grs. at nearly low water. 
* Highest tides are on third day of new or full moon,
