I was astonished to see, from a published letter of Mr. Ryland's, that 

 Mr. Hudson had informed him that the prize to Cambridge was sus- 

 pended. From this circumstance I was induced to look at my memo- 

 randa, and there I find this information given to me by one of the 

 gentlemen of Messrs. Ryland and Dean's concern : — " The size of each 

 of the two cylinders is Scinches in diameter, and the horse-power is 5^." 

 I objected to this as not indicating the proper power with steam at 

 50 lbs. pressure ; but the gentleman disputed the point with me. Now, 

 according to Templeton's table, a 5i incli diameter cylinder is equal to 

 4-horse power, so that two of these are equal to 8-horse power instead 

 of a 5k horse power, as stated by them. The value of this statement, 

 as well as of the objections which Mr. Ryland has made to the decision 

 we came to, ^Yill, I have no doubt, be taken by you at the full amount 

 of what it is worth. 



All the measurements in the above statement were taken in your 

 presence, and you will of course alter any which are not perfectly correct 

 in every part. I am, dear Sir, 



Yours faithfuUv,
