INVESTIGATIONS ON HYDROPHOBIA IN EUROPE, 227 
returns lately published in France, that out of 181 cases of 
rabies in human beings, 40 were recorded in Uecember, 
January, and February; 44 in March, April, and May; 66 
in June, July, and August; and 31 in September, October, 
and November. Out of 147 cases of rabies noted in France, 
the period of incubation was, in 26 cases, less than one 
month; in 93 cases, from one to three months; in 19 cases, 
from three to six months; and, in 9 cases, from six to twelve 
months. Out of l6l cases observed in France, the duration 
of confirmed rabies was not more than two days in 34 cases ; 
four days in 98 cases; six days in 24 cases; seven days in 
two cases; eight days in 1 case; and nine days in 1 case. 
In England and Wales the deaths from rabies were 25 in 
1851, 15 in 1852, 11 in 1853, 16 in 1854, 14 in 1855, 5 in 
1856, 3 in 1857, and 2 in 1858. In Prussia the deaths from 
the same cause were 20 in 1844, 15 in 1845, and 28 in 1846. 
In the Austrian empire the deaths from rabies were 589 
from 1830 to 1838, and 449 from 1839 to 1847. In Bavaria 
there were 39 from 1844 to 1850. In 1851 the disease 
reigned epidemically in the north of Germany; at that 
period no less than 267 cases of rabies were observed in dogs 
at Hamburg and its vicinity. From 1829 to 1854, 35 
patients suffering from rabies were received into the Great 
Hospital at Milan (19 males and 16 females). In 1832, '33, 
’36, '39, *47, and '50, no cases of rabies were*received in that 
hospital; but 5 were admitted in 1849, 4 in 1838, 4 in 1854, 
3 in 1851, and 2 in 1830, '35, '37, and '48. In the other 
years only 1 case was admitted. Out of these 35 patients, 
17 were less than fifteen years old—an enormous proportion, 
which is probably the result of the habit of children playing 
with animals. In none of these 35 patients did the symptoms 
appear before the fifteenth day, and with one of them the in¬ 
cubation was from 170 to 175 days. With none of these 
patients did death occur before the twenty-fifth hour after 
the appearance of the first symptoms. The author himself, 
however, saw a case of rabies at the hospital of Versailles, in 
1846, where the patient died two hours after the disease had 
appeared. From ether figures mentioned by the author, it 
is proved that neither the muzzling of dogs nor the cold 
season of the year supplies a safeguard against the rabid 
bites of these animals. 
The author has also arrived at the following conclusions :— 
1. We may estimate the number of dogs in Europe at more 
than twelve millions, and the cost of their keep at a million 
francs per diem, or half a milliard per annum. The annual 
number of victims amounts to several hundreds. 2. In the
