The first is about the Edinburgh Sweating Club; I kid you not. First appearing in 1750, this was apparently a band of young rogues who would go out drinking in the local hostelries and at midnight would sally forth and terrorise the local populace by snatching wigs off passers-by, chasing and jostling others. It is an interesting and amusing article.
A couple of pages further on in the same issue is a list of the members of the New Associate Congregation, Edinburgh (1785). Have a look as you may find your ancestor listed; it gives names and place of residence.
Ever wondered where your ancestor went to school? Another article in the same magazine is titled Scottish Charity Schools in the early 18th century. This is a list of the charity schools run by the Society in Scotland for Propagating Christian Knowledge (SPCK) dated May 1724. It gives the date of opening, place, parish, name of School-master, number of pupils divided into boys and girls.
