Nice finds. There has been a good bit of interest in diving among bottle collectors in recent years.
The first bottle, likely soda, W. C. O'Malley, Clinton, MASS is more interesting than most in that it has the manufacturing info on the base. Check sodasandbeers.com to see if it is listed.
The second is a generic whiskey bottle. Like the first, your bottles date from either the 1890s or perhaps a smidge later. Have not seen one with such dramatic embossing like this, kinda cool although not worth that much.
