To the combined influence of the Sea and the Humber in mitigating the heat 

 of the summer day and softeniog the cold of the winter's night at Hull, a third 

 may be added, namely, the large surface area of water, which in the form of spacious 

 docks and harbour occupy a space of from CO to 70 acres. The effect of this 

 area of water passing through the centre of the town must be in summer to absorb 

 heat, which houses, streets, or dry ground would reflect into the atmosphere, and in 

 winter to communicate during the night a portion of the heat absorbed during the day. 



It is to be much regretted that no data whatever exist as to the temperature of 

 the docks, the Humber, and the sea washing the Yorkshire coast, a blank in meteo- 

 rological science which the author hopes to fill up. 



It may next be interesting to show the extreme monthly maxima and minima 

 registered at Hull. For this purpose Table IV. is constructed, showing the highest 

 and lowest monthly maxima and minima from the observations of Dr. Fielding and 

 Mr. Lawton, to which is added a similar table again copied from Professor Phillips's 

 work before mentioned. 



Table IV. — Extreme Monthly Temperature. 



From this table the influence of adjacent waters in raising the temperature of 

 January and December, at Hull, compared with the same months at York, is more 

 ajiparent. 



Following this table is another. Table V., also of extremes, which is formed from 

 Dr. Fielding's observations alone, by taking the highest and lowest point registered 

 on any day in each month of the six years. 



Table V. — Dr. Fielding's Extreme Temperatures. 



The temperature of 85-5, in Table V., was registered on the 10th of August, 1835
