below it. "When the ice was melted animalcules were found 

 to have maintained their vitality, and in two hours they re- 

 sumed their original activity. This corroborates the experi- 

 ments of Professor Melsens, who ascertained that the most in- 

 tense cold does not destroy the active power of vaccine lymph.

SANITARY CONDITIONS OF CERTAIN GEOLOGICAL FORMATIONS. 



Dr. Moffatt, in discussing the relation of health to certain 

 geological formations at the late meeting of the British As- 

 sociation, remarked that the district in which he lived con- 

 sisted geologically of the carboniferous and of the new red 

 sandstone system ; that the inhabitants of the former were 

 engaged in mining and agriculture, and those of the latter in 

 agriculture chiefly. Ana?mia, with goitre, was very preva- 

 lent among persons living on the carboniferous system, while 

 it was almost unknown anions; those on the new red sand- 

 stone ; and phthisis was also more prevalent among the for- 

 mer than the latter. He then gave some statistics as to the 

 diseases prevalent in the counties of Chester, Flint, and Den- 

 bigh, and stated that the practical deductions to be drawn 

 from the inquiry were that all young persons living on a 

 carboniferous formation, having symptoms of incipient goitre 

 and anaemia, ought to be moved to a soil of red sandstone, 

 and persons of strumous habit ought to reside upon sand- 

 stone at an elevation of at least 800 to 1000 feet above the 

 sea. 



In the discussion which followed the reading of this paper, 

 Mr. G. A. Latour mentioned a carboniferous district in North- 

 umberland containing a thin bed of -limestone, where the peo- 

 ple suffered from goitre. Sir Richard Griffith remarked that 

 goitre was unknown in Ireland, although they had plenty of 

 carboniferous rocks. Professor Hall agreed with Dr. Moffatt 

 respecting the healthful character of the new red sandstone.

WATERING STREETS WITH SALINE SOLUTIONS. 



The subject of watering the streets of cities with saline 

 solutions, which, by their hygrometric properties, shall reduce 

 the amount of evaporation, and consequently the frequency 

 of application, is one that has excited much interest ; and
