§ 37 On Auxiliary Operations on Glass:
Boring Holes through Glass. — This is much more easily done than is generally supposed. The best mode of procedure depends on the circumstances. The following three cases will be considered:-
1. Boring holes up to one-quarter inch diameter through thick glass (say over one-eighth inch), or rather larger holes through thin glass.
2. Boring holes of any size through thick glass.
3. Boring round holes through ordinary window glass.
