56 Dr. Bottomley on the late 



pox. As a test of its value he has taken the small-pox 

 statistics of London — the best vaccinated town in the 

 country — and compared the results of the five years 1849-52, 

 before vaccination was made compulsory, with those of 

 the five years 1869-73, when compulsory vaccination had 

 been twenty years in operation ; the results confirm him in 

 his previous opinion that vaccination had ceased to be a 

 remedy. He states, "so far from vaccination having been 

 the means of saving many thousand lives annually, as has 

 often been very rashly stated, the stern facts recorded in 

 the annual reports of the Registrar General prove beyond 

 all question that, in the best vaccinated city in the kingdom, 

 the death rate among the vaccinated alone is now equal to 

 that which prevailed among the unvaccinated before com- 

 pulsory vaccination laws were passed ; that the number of 

 cases from small-pox has nearly doubled, and that the 

 number of deaths of adults has also greatly increased."

 Lunar Crater near Hyginus, made at the Observatory, Birk- 

 dale"; "On the Meteorological Effects of the position of the 

 Moon with respect to the Sun." From observations made 

 at Southport, he concludes that at Southport, during the 

 winter months, the mean daily range of temperature is on 

 the average greater on the days of full moon than on the 

 days of new moon. From cloud observations, he finds that 

 at 9 a.m., the mean amount of cloud is slightly greater on 

 days of new moon than on days of full moon ; at I p.m. the 

 amounts are nearly equal ; but at 9 p.m. the amount on 

 days of full moon is greater than on days of new moon. It 

 has been supposed by some meteorologists that the full 

 moon had the effect of partially dispersing the clouds, but 

 his own results show very clearly that any effect which the 

 moon may have is of an opposite character, as in every winter
