The deaths are from Mr. Luxton's returns. 
The granite region of Dartmoor in the Tavistock Union (half of 
the entire moorland) has an area of 73,386 acres, and a mean 
population of 4,194. Its death-rate from Consumption is 0-86, 
being the same as that of the Devonian region west of Exmoor. 
The excess of Sheepstor (4*0 E.) is explained by one family. The 
mean female population of Sheepstor is 50. Mr. Willis, of Horra- 
bridge, writes me, that the two females who died (4-0 p.c.) were 
two sisters ; another sister is at present ill of Phthisis ; a brother 
has had an allied illness ; a brother and two sisters of the grand- 
father, on the mother's side, died of Phthisis. The family have 
resided in Sheepstor since 1863. Excluding this strong hereditary 
case, the death-rate of the granite region is 0*78, being, with the 
Exmoor region, the smallest yet known in Devon. It is a region of 
rain, mist, westerly winds, relatively pure air, excess of ozone, and 
of active atmospheric physical changes, of a general out-of-door life.
