This is probably the iiiost satisf'actory result as abüut the mean of tlie prcvious 

 tables. We accordiiigly concliule that thore is a very slight relation betweea 

 Status and recovery froni attaek.

It would be interesting to conipare the special classes gronped as metal 

 workers in Glasgow, with those enibraeed undcr the sarne heading in the Registrar- 

 General's Reports. 



(5) Conclnsions. 



(i) The Statistical constants for vaccination and sniallpox difter sensibly for 

 the same place with two different epidemics, i.e. epidemics seem to be differentiated 

 in character. 



(ii) The statistics of Glasgow do not indicate that those of lower statns 

 — and therefore probably worse nourished and housed — provide the bulk of non- 

 vaccinated cases. On the contrary there seems to be a slight tendency for the 

 non-vaccinated to be of higher statns. 



(iii) There is a slight althongh scareely sensible correlation between statns 

 and power to resist a sniallpox attaek. 



The Glasgow .statistics do not go very ftir, but as far as they go they do not 

 justify the Statement: That the apparent protection of vaccination is dne to the 

 nnvaccinated belonging to classes of lower statns which have a far smaller power 

 of resistance to the di.sease than the better nourished classes of a higher statns in 

 which the members are more generally vaccinated. 



I have not dealt with the statistics as to female patients as the great bulk of 

 them are classified merely as " Housewives," which throws no light on their social 

 Position. 



In concludiüg this paper I venture to express the liope that the statistics 

 uf the recent London epidemic may soon be issued and in a form which will 

 adniit of due consideration of the problems referred to in this paper. Their 

 magnitude gives them extreme valne and their publication is no doubt anxiously 

 awaited by a wide circle of scientific iuquirers at home and abroad.
