current (Z, we have the result of which a few cases were collected and given in Table XII. 
section 3, and shown graphically in Plate III. fig. 5. The result is further confirmed 
when the entry in column 3 corresponds in direction with that in column 1. 
When the directions recorded in columns 1, 2, and 3 are d, and d respectively, we 
have the results given in Table XII. section 4. 
As I shall have occasion to refer incidentally to the possible influence of heat or 
cold, &c. over the relative values of the currents registered in the three columns of 
Table XIII., I have given in Table XIV. the Meteorological Eegister taken at Ton- 
bridge, and kindly furnished to me by Dr. Fielding. The barometer readings are 
corrected and reduced to sea-level at 32°.

In Table , XV. is given an analysis of the contents of Table XIII. Observations of a 
like character (as well as others to be hereafter referred to) Avere taken during the 
month of November. I have not thought it necessary to give them in detail, but have 
included a summary of them in this Table together with those of October.
