lection at length fails, when the animal 
runs off wandering without confcioulnels, 
committing ravages as he proceeds, and 
dies about the feventh or eighth day. 
In the laft day their fight, as well as 
recollection feems to be loft. In one 
initance, at leaft, I think this obfervation 
verified. 
In September, 1802, walking from 
Weltmintter-bridge, acrofs the fields to 
the Borough, | met a concourfe of peo- 
ple in purfuit of a mad dog, which was 
only a fhort way betore them. ‘ My 
fervant, feeing the animal approach us, 
gave the alarm, and we ran to one iide. 
The track the animal kept was in a 
direct line with the rails of the obelifk, 
again(t which, as it ran with confider- 
able force, it dafhed its head and feil; 
the purfuers coming up, immediately dif 
patched it. JI am inclined therefore 
to conclude, that, in the lait day of the 
difeafe, blindnefs may be enumerated 
among the fymptoms. 
{ thall teel myfelf obliged to any of 
your readers, who can produce well~au- 
thenticated facts on the fubject of the 
rabid dog, which bas contracted the 
difeafe, either fpontaneoully, or in con- 
fequence of a bite; for it is vain to 
contend, that by the latter only the 
canine virus is propagated. Minute, 
but continued alterations in the various 
fecretions from innumerable fources, 
though the chief [think may be afcribable 
to food, weather, and fituation may be 
adequate, without a bite, to the forma- 
tion of the difeafe. 
I have beftowed confiderable atten- 
tion on the fubjeét, and with to continue 
my relearches. It is an inveitigation 
well meriting our labour. We take the 
animal to our bofoms, we load him with 
our carefles; he is a faithful friend, and 
an ufeful fervant; he guards our houfes 
and tends our flocks. In proportion, 
therefore, to his familiarity with us, is 
our danger, when he is under this, 
hitherto, incurable difeafe, Few qua- 
trupeds, bitten by a rabid dog, efcape 
infection; and it is evident how detri- 
mental he then may become to the 
hive ftock of the farmer, or ftud of the 
gentleman, The effects on the human 
ipecies is ftill move deplorable ; yet it 
is fome confolation, that at an average, 
formed on a pretty wide fcale, not above

If proper means be taken, to free

sik, 
AM encouraged by your invitation, 
at page 516 of the December Ma- 
gazine (vol. xx.) to offer a few re- 
marks, im addition to the many judi-~ 
cious ones, by Aquarius, at pages 436 
to 439 of the fame Humber, on the 
fubject of procuring a jupply of whole- 
fome water for doineftic purpofes; my 
pretent delign is, to treat of {pring wa- 
ter only. The many far-fetched and 
tancitul hypothefes which philoiophers 
have invented, for railing water for fup- 
plying the earth with {prings, have at 
length given way to the mure fimple 
and rational theory, which accounts 
for every known i{pming, by the decent 
and filtration of the water, fupplied 
on the furface by rains, dews, &c. In 
fome inftances the water percolates 
through gravel, fand, or other porous 
matters, On or near the furtace, to {mall 
depths only, betore its progrefs down- 
wards is arretted, by clay or other water- 
light matters below, and the water is 
either held up, fo as to fully faturate 
the porous matter, fometimes to the 
very furtace, ‘or the fame foakes away 
laterally on or near to the inclining 
furface of the clay, &c. beneath, until 
it arrives at fome lower place, where 
the {pring veuts itfelf on the {urtace ; 
of this kind are all the {prings in and 
near London, which are reached by fhal~ 
low wells: below the level and in the 
vicinity of the Thames, the furface, gra~

It is to Mr. William Smith, a gentle- 
man who has devoted many years to 
the minute inveftigation of the ftrata 
of the Britifh Iflands, that we are prin- 
cipally indebted for a general knowledge 
of the more powertul and univerfal 
iptings, which are to be reached by deep 
wells: it is true, that deep wells in fome 
diftricts, as on the chalk downs, near 
Brighton, Lewes, &c. in Suffex, belong 
to the cafe already mentioned; the
