Seventy-Six Years Old.Dr. Robert Griffis yesterday ce’e-brated his 7bth birthday. On tne 17th of June next he will have been in Middletown an even half century. During this time he has witnessed many changes in the town and surrounding country. He is the only man left in Middletown, who was at the head of a family when he came here, and there are very few houses now standing that were here then. Dr. Griffis for a man of 7H is still in fairly good health and is quite active. His numerous friends hope he may live to celebrate many more birthdays.
