"It is a common Maxim amongst Merchants,that no Town can enjoy a flourishing Trade, except its Inhabitants permit the Jews to settle amongst them. This Maxim, as it should seem, has prevailed in Hamburg; since there arc above thirty-five Thousand Jews in that City. Many of these inhabit Part of the New Town, towards Altena. The Streets occupied by the Jews are pretty large, but consist of very poor Houses. They have here, as in other Places, several Marks of Distinction, by which they are easily known."The estimated Jewish population, which would have been Ashkenazi as well as Sephardi, may be exaggerated in this report.
