6. Observations on the influence of Cold on New-born Children. 
Dr. Trevisan has been making researches in Italy, principally at 
Castle Franco, analogous to those of M. M. Villermi, and Milne Ed- 
wards, in France. The conclusions at which he arrives, are :—In 
Italy, of one hundred Infants born in December, January, and Feb- 
ruary, sixty six died in the first month, fifteen more in the course of 
the year, and nineteen survived ; of one hundred born in spring, forty 
eight survive the first year; of one hundred born in summer, eighty 
three survive the first year; of one hundred born in autumn, fifty 
eight survive the first twelve months. He attributes this mortality of 
the infants solely to the practice of exposing them to cold air a few 
days after their birth, for the purpose of having them baptized at the 
church. As well as M. M. Milne, Edwards, and Villermi, Dr. Tre- 
visan calls the attention of the ecclesiastical authority to measures 
suited to put a stop to such disasters, without violating the precepts 
or practices of religion.—Jdem. 
" 't. Mortality among Leeches during storms, (Fer. Bull.) —That 
atmospheric changes have a remarkable influence upon leeches, is a 
well established fact. In 1825, M. Derheims, of St. Omer, ascribes 
the almost sudden death of them, at the approach of, or during 
storms, to the coagulation of the blood of these creatures, caused by 
the impression of the atmospheric electricity. This opinion, which 
at that time was the result of theory, he confirmed in the month of 
March last, by direct experiment—Idem.
