From llii^^nle Ihe number of (^f^«s diminlthed, until, on Nov. 3(J, there were but two new cases, and two deaths; and inimedialeljafler this the activity of ihe epidemic became su9pende<l. Taking the total nnmber of cases recunled (l.OUitI, and comparing it with the number of deaths (573), we have a mortality of 57$, — a rather startling re- sult, under the circumstances; for it may be taken for granted, that under the care of a hospital staff, if anywhere, the best resutts are lo be obtained In Ihe Ireainient of ihU disease.

The suddenness of the decline of the epidemic may be due, in pari, to the vigorous meaaui'es taken to stamp it out; but its disappearani'e is to be ascribed mostly to Ibe frosts of the last of Ihe inonlli. which
