late selected the intestinal surface as the field for his investiga-
tions, and through it b}' introducing tuberculous matter into
the circulatory current he has produced, at will, general tuber-
cle. The Union Medicale reports that he lately purchased
four handsome heifers, and he tuberculized three of them by
causing them to swallow 30 grammes each of tuberculous
matter taken from the Cost Of Toprol Xl body of an old phthisical cow. Tlie
rapidity of the result was extraordinary. At the end of twenty
days the first heifer had lost flesh to a sm-prising extent, its
pulse was quick and full, and it coughed incessantly. At the
end of fifty-two days it was killed, and it presented perfectly-
marked tuberculous lesions situated especially about the mes-
entery and intestine. The mesenteric glands presented infil-
tration in so high a degree that many were of the size of the
first. Toprol Generic Equivalent Their total mass weighed 1,650 grammes. All the
ganglia of the bronciii and mediastinum M'ere enlarged, and
the lung was full of crude tubercle. The other two heifers
presented not less perfectly-marked alterations ; while the
iburth, to whom none of the tuberculous matter had been ad-
ministered, remained intact and increased in flesh.
200 MISCELLANEOUS AND SCIENTIFIC NOTES.
It is proved, therefore, tliat animals of the bovine species
contract tuberculosis by digestive ingestion, just as they take
carbuncle and covv-])ock, as Metoprolol Vs Toprol Xl sheep take the rot, as the horse
takes glanders, and as man takes small-pox. The human
digestive tube constitutes an easy channel for tuberculous con-
tagion. If bovine phthisis be identical with tuberculosis in
the human species, there is, in the use of the flesh of tubercu-
lous animals, a danger to which- the poor are more especially
exposed. — Medical Press and Circular.
" Yentilate your Sewers ! do not trap ! Generic Name For Toprol " — These words
form the close of a very valuable address on the influence of
sewer-vapor on health, delivered by Dr. Carpenter, of Croy-
don, before the Social Science Association, and we think the
substance of it deserves the widest circulation.
It is within the memory of this generation that typhoid
fever has been distinguished from other fevers, and has been
traced to sewage. The earliest eflbrts of sanitarians were
directed to tlie abolition of those collections of impurity in
cesspools which formerly poisoned the earth, air, and water for
our forefathers ; and with the introduction of water-closets and
of tubular drainage it was hoped that typhoicl fever, at least,
might be exterminated, ll^evertheless, it did recur again and
again, as at Croydon ; because, says Dr. Carpenter :
In the early sanitary works which were carrietl out under the super-
vision and with the approval of the General Board of Health, and under
the authority of the Public Health Act of 1848, the consequences of sewer-
gas not being foreseen were not guarded Toprol Xl Generic Name against ; no provisions were made
to prevent its ascent into the house, or for exit into the open air before it
could reacli the inside of the dwelling. The rapid spread of luxurious
habits among the people, the introduction of low fireplaces and register
stoves, and the methods adopted to exclude drauglits by liaving exceed-
ingly close-fitting windows and doors, prevented the easy exit, and its
baneful influence became manifest, often without the real cause being at
that time at all suspected. It often Jiitppens that the easiest way for air
to enter the house is by the sewer.
Then, with this state of things, " fever would recur ; fever
always the same in type, ' the enteric or typhoid ' form, with
rose-colored spots, often with abdominal complications, and
always in those houses nearest to the top of the sewer (perhaps
I should say generally), and farthest from the outfall."
Nor Toprol Xl Generic Recall is fever the only consequence of the entry of sewer-gas
into Is Toprol Xl A Beta Blocker dwelling-houses. , " Many other disorders of the system,"
says Dr. Carpenter, " have been directly traced to its influence
— thus diarrhoea ; dyspepsia in all its forms; palpitation Is Toprol A Beta Blocker of the
heart ; various forms of asthma (indeed, it may help to explain
some of the vagaries of this curious disease) ; convulsions,
especially in teething infants ; headaches, both persistent and'

intermittent. Tlie evik which sometimes attend or follow
npon the puerperal state, as milk-fever, abscesses in the breast,
and ])hle«2;masia dolens or white-le;, are frequently caused by
it. I believe that these latter cases have been Toprol Xl Beta Blocker so associated,
from observing their frecpient occurrence in new Toprol Xl Vs Metoprolol Tartrate houses before Toprol Xl Vs Metoprolol
the plan now adopted Generic For Toprol Xl in our district was carried out."
In houses pervaded by sewer-gas, invalids cannot recover
their health, and delicate women are liable to faint away with-
out assignable cause ; not that " stink " is always com])lained of.
A good, honest, unabashed " solid " stink, as Dr. Carpenter calls
it — one that assails the nose without ceremony — is a fair, open
enemy. lie gives 3'ou warning, and you open your windows
and let him out as you would a hornet. On the contrary, it is
the " insidious almost imperceptible miasma" that is danger-
ous ; and it is deserving of notice that many miasms do not
stink per se^ but only when, beginning to be ozonized and de-
composed, they give rise to that which offends the nostrils. Dr.
Carpenter illustrates this by reference to some emanations from
a factory, which are often more offensive half a mile off than
at the place of issue.
How, then, Toprol Xl Coupon is, this enemy so subtle and deadly to be dealt
with ? Most sanitarians have but one reply — put efficient traps
and shut out the gas. Dr. Carpenter argues that this is useless
by itself. The sewer-gases must obey the laws of Nature, and
will find an exit at the highest point, and, unless one be pro-
vided for them, will enter houses by sinks, gully-holes, and
closets. In the autumn of 1867, nearly 40 per cent, Toprol Xl 50 Mg Recall of the
160 children of the "Warehousemen and Clerks' Schools Generic Name For Toprol Xl on
Russell Hill, and this spring about 30 per cent, of the inmates
of the Female Orphan Asylum at Beddington, suffered Toprol Xl Vs Generic from
typhoid fever through the reflux of sewer-gas by the traps.
Trapping alone, then, Dr. Carpenter concludes, is delusive ;
for not only may the trap become dry, but the water Metoprolol Tartrate Vs Toprol Xl that seals
it absorbs gas from the sewer, and gives it off into the house,
and, if there be any pressure, the trap is Toprol Xl 100 Mg forced, Neither is it
of any use to say that sewers ought to be self-cleansing, that
they ought to form no deposit and give off no gas. What ought
to be, and what actually is in this wicked world, are two very
different things. Toprol Xl Generic Equivalent
The real plan is to ventilate every sewer abundantly ; to
have a rapid and constant circulation of air through it ; so that
the sewer-gas may be diluted and decomposed as soon as formed.
In order to effect this, in the first place every house-drain ought
to be ventilated by carrying u[) the soil-pipe to the highest
available point, so that it be far enough removed from windows
and chimneys. Other ventilating shafts, straight and perpen-
dicular, ought to be put to every pipe requiring a trap, so as
