Apparatus for finding the upper boundary of fog or clouds, using a tethered balloon or kite sent aloft, with a hygrometer capable of returning information electrically to the observer on the ground.

Some handwritten revisions seem to indicate reclassification from the original AT 42i to AT 62c and maybe others.

Refers to a prior patent in Deutschland, applied for on 13 December 1909. We don't seem to have this in the database yet.
