(2) Instantaneous Shadow Photographs (life size) of the Splash of a Drop of Mercury falling 15 cm. on to Glass.
Comparing the first set of drawings (pp. 20-24) with the photographs of Series X., it will be seen that

but the irregularity of the last photograph almost masks the resemblance.
SERIES XII.
Engravings from Instantaneous Photographs (16⁄17 of the real size) of the Splash of a Drop of Mercury, 4·83 mm. in diameter, falling 8·9 cm. on to a hard polished surface.
Series XII. gives an objective view of a mercury splash as taken by the camera. Only the first of this series shows any detail in the interior. The polished surface of the mercury is, in fact, very troublesome to illuminate, and this splash proved the most difficult of all to photograph.
