 Cylinders having the following dimensions, in inches, con- 

 tain the measures stated, very closely; the diameters are 

 given first: 



Gill =lfin.X3in. I Gallon.. = 7in.X6in. 



Pint = 3|in.X3in. 8 gallons =14in.X12in. 



Quart =3|in.X6in. | 10 gallons =14in.X15in. 



*A knot is really a measure of speed and not of distance; 

 when used in this sense, it is equivalent to 1 naut. mi. in 1 hr. 

 Thus, a vessel traveling 20 naut. mi. per hr. has a speed of 

 20 knots.
