into the rumen, and a fluid slowly poured down will flow on into 
the abomasum; nay he can, if he wishes, send a fluid into the 
rumen. That newly-invented, and not sufficiently appreciated 
instrument, the stomach pump, will effect every thing for him. 
He may pass the tube fairly down the oesophagus, and thrust it 
through this singular floor of the canal, and pour medicine if he 
likes into it, if he is not afraid of producing nausea and the 
cessation of rumination by the mixture of a nauseous drug with 
the food that is to be masticated afresh ; or he may pump in his 
warm water, or any other bland fluid, until vomition is excited, 
and the fermenting and acescent mass of food contained in it is 
discharged. 
On the other hand, he may introduce the pipe but a little way 
down the oesophagus, and pump in more slowly, and the water 
will flow on over the floor of the canal, and into the manyplus, 
and wash out a portion of the hardened mass between its leaves; 
for not only, as Mr. Sumner says, “ when the third stomach is 
the seat of disease, the excrement is in a dry state,” but the 
dryness, amounting to a hardened, baked state, as it were, of the 
fibrous matter collected between the leaves of the manyplus, is 
either the cause or the consequence, but most certainly the 
accompaniment of disease of this viscus. The operator, we say, 
may pump on until he has softened or washed out a portion at 
least of this hardened mass, by which the action of the manyplus 
is paralysed; and the abomasum gradually becoming filled with 
the fluid, some regurgitation will ensue, and some of the water will 
return into and fill the manyplus, and fully accomplish the de¬ 
sired object, the removal of this indurated mass. 
Possibly we have, for the present, sufficiently answered Mr. 
Sumner’s questions. 
We were right glad to recognize in the communication of V. S. 
of P— B— the hand-writing of a valued correspondent, other¬ 
wise we should have been compelled, and most unwillingly, to 
postpone at least his observations on the paper of W. J. G. 
Without giving, and indeed which we are not at present called 
upon to give, an opinion as to the matter in dispute betw ;en
