The direction of the resultant field of force will then make, with that of H E, an angle 0, such that **Hp**/H E tan 0, and the suspended needle will be deflected through the same angle.

Then, since **Hp**, the force at M due to m and - m, is the resultant of d, and - m2, we have (L **Hp** m d d2 2ml H = d3, the direction being parallel to AB.

At A the air occupies its original position, while at H it is displaced towards the right or away from A since **HP** is above the axis.

In that short time the displacement at H decreases from **HP** to **HP**' or by PP'.

In that short time the displacement at H decreases from **HP** to **HP**' or by PP'.

APIS or Hapis, the sacred bull of Memphis, in Egyptian **Hp**, Hape, Hope.

Hypophosphorous acid, **HP**(OH) 2, discovered by Dulong in 1816, and obtained crystalline by Thomson in 1874 (Ber., 7, P. 994), is prepared in the form of its barium salt by warming phosphorus with baryta water, removing the excess of baryta by carbon dioxide, and crystallizing the filtrate.

We thus obtain the differential equation gk(d 2 0/dx 2) =cgdo/dt+**hpo**, which is satisfied by terms of the type =c" sin where a 2 -b 2 = **hp**/qk, and ab = urnc/k.
