310 Meteorological Observations at Hudson, Ohio. 



asked, while upon the second mode she would stand as she 

 deserves, high in the scale of health, and lead to the demand of 

 a small premium. As the question is one of figures, and I have 

 stated the data, the problem may be easily solved, and the result 

 I am satisfied will be conclusive as to the justness of the prin- 

 ciple I lay down for our rule of conduct on the two occasions I 

 have mentioned above. It may be said in favor of continuing 

 the old form in the bills of mortaHty, that as the deaths from 

 all causes are enumerated in them in every country where they 

 are published, the influence of the accidental sources of death I 

 object to would operate equally in one place as in another ; such 

 an argument has in fact been urged when I have introduced the 

 subject in conversation, but its weakness must be apparent when 

 we reflect upon the very great difl'erence in the proportionate 

 number of mortal accidents in diflerent countries ; in cities for 

 instance they are numerous, and in some much greater than in 

 others. 



Art. VI. — Meteorological Observations made at Hudson, Ohio, 

 lat. 41° 14' 40'' N. ; lo7ig. 5'' 25^ 47^5 W. ; during the 

 year's 1838, 1839 and 1840 ; by Elias Loomis, Prof of Mathe- 

 matics and Natural Philosophy in Western Reserve College. 



In the autumn of 1837 I arrived at Hudson with a set of 

 meteorological and other instruments, recently purchased in 

 Europe. It was some time before a suitable place could be pro- 

 vided for their reception, and they were not observed with much 

 regularity until March, 1838. During the first three months the 

 register was frequently interrupted, but since August, 1838, only 

 one observation has been lost, in vol. xxxvi. pp. 165-173 of 

 this Journal, is given a specimen of the register and a description 

 of the instruments. It will be sufficient to add, that the position 

 of the instruments has throughout remained unchanged, and the 

 same hours of observation adhered to. It is proposed now to 



population, which the retention of their causes in the bills I object to made appa- 

 rent, was the reason why an insurance company in England refused to continue a 

 policy on the life of Mr. Dunglison when about to embark for the United States, 

 unless the premium were doubled. — Dunglison's Hygiene, Sect. i,p. 132.
