We have already noticed this invention. When it becomes cheap it will be one of the best insurances we can have against hail storms for our glass-houses. The Boston Journal of Chemistry, referring to 'it, says:

" Essentially, the process consists in heating glass nearly up to the softening point, and then plunging it into a bath of oil or grease. But to bring it to perfection has needed the patient experience of seven long years. M. Bastie, who is a gentleman of fortune, is said to have made his discovery first some seven years ago. This was after many years of investigation. But though he seemed to have succeeded for the moment, it took two years more of continual experiments before he could repeat his success. The invention has been patented in all European countries, and soon will be throughout the civilized world."
