The mixture probably contained also some **BH** 3.

If these equations could be assumed to hold when H is indefinitely small, it would follow that has a finite initial value, from which there would be no appreciable deviation in fields so weak that **bH** was negligibly small in comparison with a.

Thus we shall call the first inclined line on the left hand the line AG, the line representing the first force on the top left-hand joint AB, the first horizontal member at the top left hand the line **BH**, &c; similarly each point requires at least three letters to denote it; the top first left-hand joint may be called Abhg, being the point where these four spaces meet.

The rods BC and DB carry two small rods EF, GF jointed at F; at this joint there is a pin which slides in a slot on the rod **BH**, which is normal to the mirror X.

€vea and **bh** to b (beran = Lat.

Be the middle points of AC BD...; then **BH**, CK...

Ating straight lines of each, which will form their line of contact, and will be inclined to the axes AG, **BH** in opposite directions.

The aspirated mediae **bh**, dh, gh, gh were treated as unaspirated b, d, g, g; probably also the rare aspirated tenues fell together with the unaspirated.

Change of the original aspirates gh, dh, **bh** (=x, 9, ~) into th corresponding medials Sanskrit.
