New method of Lighting large Apartments. 385 
12. Successful treatment of Hydrophobia.—On the 28th of 
October last, a young apothecary was bitten in the left hand 
by acat, which died two days alter with confirmed madness. 
He satisfied himself with washing the wound, and pressing 
out the blood. Twenty-four hours after, he cauterized the 
part superficially, Recommended by his physician to M. 
Rossi of Turin, the latter discovered in the wound marks of 
the peculiar virus, and prescribed a drink of pure vinegar 
every morning, and two glasses of a decoction of jun.per (ge- 
nista lateotinctora) during the day. It was deemed necessary 
particularly to examine the small glands under the tongue. 
In the early part of December, unfavourable symptoms 
began toappear. The patient lost his vivacity, became taci- 
turn, seeking retired places, and weeping abundantly. His 
sleep was short and restless, his complexion livid, and his 
eye fiery. His physician then perceived that the leit gland 
was swollen and inflamed. He immediately ordered a deep 
cauterization upon the two glands, by means of a red hot 
iron. This painful but necessary operation was followed by 
a violent access of fever, which gradually declined, and finally 
disappeared on the third day. From that time the patient 
has been perfectly restored, and has not experienced the 
least sensation from his wound.—Jbid. 
13. New method of Lighting large Apartmenis.—M. Loca- 
telli, a mechanician of Venice, distinguished by many impor 
tant discoveries, has invented a new process for lighting pub- 
lic halls. It is well known that Rumford and others endea- 
voured in vain to discover the means of dispensing with chan- 
deliers, so inconvenient in theatres and other halls of audi- 
ence. The new process employed at Venice has compietely 
succeeded, and leaves nothing to be desired. Instead of pa- 
rabolic mirrors, the light of several lanterns 1s concentrated 
on an opening in the middle of the hall, (probably the ceiling,) 
and falls upon a system of lenses, plano-concave, which fill 
the opening, (a foot in diameter,) and distribute through the 
apartment rays, which, falling parallel on the lenses, issue 
divergingly. From the centre, or pit, nothing is perceived 
but the lenses, which resemble a chaffing-dish of burning 
coals, illuminating the whole house, without dazzling or 
fatiguing the eye. Besides the advantage of being more 
equal and soft, the light is more intense than that of the chan- 
¥ou. X. No.2. 49
