this stomach, in reference to those for regurgitation, that is to 

 be ascribed on one hand the facility which ruminant animals 

 have of regurgitating, that is to say, by the throwing up into the 

 mouth the substances contained in the first two stomachs, and, 

 on the other hand, the difficulty which they have in vomiting, i. e. 

 in rejecting and bringing back into the mouth the substance con- 

 tained in the fourth stomach. If it be recollected, that this 

 fourth stomach is that where the definite conversion of the ali- 

 ment into chyme takes place, that which contains the ruminated 

 substances, the substances which consequently must no longer 

 return to the mouth, whilst the first two stomachs, on the con- 

 trary, are those where the aliment undergoes only a certain pre- 

 paration, those which contain only the substances not ruminat- 

 ed, the substances which consequently must return into the 

 mouth, we shall soon see why every thing must be disposed 

 to render easy the rejection of the two first stomachs, and that 

 of the fourth very difficult. Without this arrangement in fact, 

 the ruminated substances contained in the fourth stomach 

 would be constantly mixed together, confounded and brought 

 back into the mouth, with the substances not ruminated, a con- 

 fusion which must be an obstacle to the accomplishment of the 

 end which nature proposed to herself to attain by the act of ru 

 mination. — Dublin Journ. of' Med. and Chem. Science^ May

ARTS. 



16. Clay for Sculptors, — Sculptors who prepare their models 

 in clay, have frequently occasion to leave their work for a long 

 time unfinished ; and, in such cases, often experience much dif- 

 ficulty from the drying and shrinking of the material. It is 

 well to know, that, by the addition of 10 to 15 per cent, of mu- 

 riate of lime, well worked or kneaded into this clay, it will be 

 preserved for almost any length of time in a moist state, and fit 

 for a renewal of the work without any preparation. 



17. Lutefoyr Bottling Wine^ ^c. — One part resin, one-fourth 

 part yellow-wax, one-sixteenth part tallow ; add one-half part 

 yellow ochre, or red or black ochre, or coal. Keep these ingre- 

 dients melted over a chafing-dish; and, whch the bottle is >vcll 

 corked, dip the neck into the melted rtiasS.^^'i <»J jK»n'jmo«»fk|
