Arr. XTII.—Temperature of the cities of Rome (Italy) and 
New York; by Jeremian Van Renssevarr, M. D. (now resid- 
ing in Rome.) 
TO PROFESSOR SILLIMAN. 
Sir—It was deemed advisable early last year that one of my 
children should pass some time in a milder climate than we enjoy 
in New York, and I determined to take my family to France, 
Switzerland, and Italy. 
When the cold weather drove us from Florence in December, 
we found at Rome that delicious temperature, and mild, balmy 
air so grateful to the invalid, and there we spent the residue of 
the season. Indeed, the effects were so cheering, that I have 
come to this city to make the necessary arrangements for a resi- 
dence of some years in that delightful climate. 
Since my return, very many applications have been made for 
a comparison of the climates of New York and Rome. It so 
happens that I have with me a fragment of a register I kept in 
the latter place, and have prefixed to it an extract from a meteo- 
rological journal most accurately kept by a highly intelligent and 
observing lady of this city—thus showing the temperature of 
each place. Isend them to you for insertion, should you deem 
them of sufficient importance or interest to occupy a page or two 
of your valuable Journal. 
The range of the thermometer speaks for itself ; but I may add, 
that vegetation continued green, the orange-trees under our win- 
dows were covered with fruit, and many of our rose-bushes were 
never without. flowers during the winter. ‘The inhabitants nev- 
seeiels called it a bad season. 
For incipient diseases of the chest, the climate is admirable, 
and therefore I am induced to remain. 'These maladies are very 
rare among the natives, as may be learned from the fact that at 
the general hospital, Santo Spirito, where there are eighteen hun- 
dred beds, besides two hundred kept for accidents, and where all 
disorders are admitted, amounting to nearly twenty thousand im 
the year, the number of patients with diseases of the chest and 
lungs in 1840 was one hundred and seventeen.
