- 393 394
- Description:
- In each case the conditions (so far as we know them) existing between cloud and earth, or vice versa, have been carried out as closely as possible, and I would call special attention to the following facts, viz.:
1st. That, all the discharges have been in a plane absolutely parallel with the plate.
2nd. That, notwithstanding this, in several cases, the discharge has taken an abrupt break of 90°, thus showing the possibility of the so-called “painter’s lightning,” it being impossible in nature to estimate the plane of a flash, whether approaching or receding.
3rd. That in the print representing the ordinary meandering flash, not only have the bright “knots,” (frequently photographed in nature) been reproduced, but also the wider flash, which is obviously of a multiple character and which has been ascribed to various causes, all of which have been as far as possible eliminated in the present instance. - Exhibit type:
