The succeeding ten years, 1793-1802, repeat much the same tale, with, however, a diminution of mortality in an increasing population, and a decrease in smallpox with an increase in measles and whooping-cough: thus—

Considering these figures said Watt—
I remarked that the deaths by Smallpox were chiefly in infancy; hence the deaths under two or three years of age bore a very great proportion to the whole deaths in the city. Taking an average of several years, I found that more than half the human species died before they were ten years of age, and that of this half more than a third died of the Smallpox; so that nearly a fifth part of all that were born alive perished by this dreadful malady.
Watt meant of course the human species as exhibited in Glasgow, of whom more than half died before the age of ten, and a fifth of smallpox. What was true for a time of Glasgow smallpox was not even true of Edinburgh, much less of the whole earth.
Variolation was practised in Glasgow, but to what extent appears to be unknown. Certain, however, it is that smallpox was as little dreaded as are other calamities accounted common and unavoidable. Indeed many were not unwilling to subject their offspring to the disease at seasons supposed to be favourable on the principle of “getting a bad job over.” Then, too, the mass of the population was disposed as if by design for the generation of febrile ailments. Tall buildings forming narrow lanes, wynds, or closes issued like so many rents or fissures from the leading thoroughfares. These buildings were divided into flats packed with humanity from basement to attic. Air and light were treated as superfluities. Water there was none, save what was brought from wells; and middens received the slops and refuse often shot from the windows. Life in a Glasgow wynd in former days is indescribable, yea almost inconceivable; yet in such wynds multitudes passed their existence, conscious of no hardship, recognising nothing better, and withal characterised by many virtues. Bearing such conditions in mind, the vital statistics of Glasgow excite no surprise: the wonder is that the death-rate did not draw nearer to extermination. As for smallpox, how could a family resident in a flat in a noisome Glasgow close at the end of last century escape smallpox, if smallpox were prevalent? To them smallpox lay in fate, and was accepted on the same terms as wind and weather, summer and winter.
Novelties have always had a ready welcome in Glasgow, and when cheap and easy salvation from smallpox was proclaimed, there was a rush for it. Smallpox abated: vaccination had the credit: and faith was justified. Considering the devastation smallpox had wrought among the young, Watt says—
