PROVISIONAL REPORTS, AND NOTICES. 44]

same subject. 
*“T have also made some progress in the discussion of the 
heights with a view to the determination of the best anterior 
epoch, and to the solar correction. I have laid down the two 
years’ observations made by means of my machine, but have 
not obtained any of the correction curves as yet. 
“« The two tide-gauges for the East Indies are very nearly com- 
pleted. I have had a visit from another engineer officer in the 
Company’s service, a Lieut. Ludlow, who stayed here three or 
four days to study my machine. Lieut. Elliott has written to say 
he intends coming again to Bristol, as soon as the new instru- 
ments are finished, in order to make himself more perfectly ac- 
quainted with all their details. Both these gentlemen expressed 
themselves as being highly pleased with my tide-gauge. It has 
been working now for more than seven months without the slight- 
est derangement, or the loss of a single observation. 
**T do not think that I mentioned to you the extraordinary tide 
which occurred here in October, 1838, when the water in our 
river rose to nearly 8 feet above its proper height, in consequence 
of a hurricane, as shown by the adjacent heights of the series

On Waves.—By a Committee, consisting of Sir J. Robison 
and J. 8S. Russell, Esq. 
All the objects which had been confided to this Committee 
having been fully accomplished, the report now presented was 
to be considered as final. The objects originally committed to 
them for investigation were—the Phenomena of Waves propa- 
gated in Liquids; the connexion of these Phenomena with the 
resistance of Liquids to the motion of Floating Bodies ; and the 
nature of the connexion which subsists between the Tidal 
Wave and Mr. Russell’s great solitary Wave of Translation. 
Since the publication of their furmer report, the phenomena 
of Waves had occupied the attention of eminent mathematicians, 
who had endeavoured to deduce from first principles the curi-
