with ; touch as closely as possible. Thus, a plane 
or a circle is said to osculate a curve when it has three 
coincident points in common with the curve that is, it 
occupies such a position (and in the case of the circle has 
such a size) that as it is brought up into this position 
three points of intersection with the curve run into one. 
A sphere is said to osculate a tortuous curve when it has 
four coincident points in common with the curve. In 
these cases, to osculate means to have the greatest number 
of coincident and successive points common to a fixed lo- 
cus which is compatible with the general character of the 
locus which osculates; and some geometers restrict the 
word to this meaning. This meaning is also extended to 
time : thus, the osculating elements of a planet are those 
elliptic elements which would satisfy three exact obser- 
vations made at times infinitely little removed from a 
given epoch. But osculate is also used loosely to mean 
merely that the loci in question have three or more coin- 
cident points in common. A tangent-line or -plane is never 
said to osculate a curve or surface unless it has more than 
ordinary contact with it.
