The Recent Explosion. – No additional deaths from the explosion were reported yesterday up to 3 o'clock. There was a rumor at the Laboratory that two more were dead, but it was not confirmed. Of those who were reported in yesterday's paper as wounded, it is believed that the greater portion will recover, though some four or five are in a dangerous situation. The subscriptions for the relief of the needs have been quite liberal.
