Note 176 — PART SECOND. (continued 3)

No greater latitude, or very little more, is required by the advocates for the contagious nature of the yellow fever than Dr. Seaman must allow in a distemper which he himself owns to be contagious. It is well known, on the eastern continent at least, that a gonorrhœa will come on at any time between the first and fifteenth day after the infection is received. Dr. Guthrie supposes the time intervening between the reception of pestilential contagion and the appearance of the symptoms to be four days; and Dr. Chisholm thinks that in the Boullam fever it is somewhat short of two days: but it is plain that much must depend on the quantity of contagion, and the predisposition of the body to receive it.
