o. The residue of 2, is pulverized if 

 need be, and digested for sometime with 

 moderately concentrated hydrochloric acid. 

 The diluted solution is filtered off and 

 washed, the residue weighed as sand and 

 insoluble matters. 



4. The solution 3, is brought to the bulk 

 of three or four liquid ounces mixed with 

 rather more than its volume of strong- 

 alcohol and enough sulphuric acid to unite 

 with all the lime which is thereby complete- 

 ly separated as sulphate. The liquid is fil- 

 tered off, the sulphate of lime is washed 

 with dilute alcohol, dried and weighed j 

 from it is calculated the amount of lime. 



5. The solution 4, is evaporated until the 

 alcohol is removed, then without filtration, 

 to it is added an excess of a liquid made by 

 dissolving i 

 of sulphate of magnesia, 41 grams of chlo 

 rid oAammonium, 37 h grams of tartaric 

 acid, and 40 grams of carbonate of ammo-

Faults Pompey Couldn't Remember. 



A clergyman, wishing to be rid of his 

 horse, and try for a better one, directed the 

 old negro man to sell his beast for what he 

 would bring, or to exchange him for another, 

 adding, at the same time, an anxious caution 

 not to deceive the purchaser, and even enu- 

 merating the faults of the animal, lest one 

 should be overlooked. 



"Remember, Pompey, he has four faults." 

 " Oh, yes, Massa, I remember." 

 Pompey jogging along the road, and count- 

 ing over the list to himself, as the old lady 

 over heijduggage, " Big box, little box, band- 

 box, bundle," was overtaken by a man on 

 horseback, who entered into conversation, and 

 among other topics, made some inquiries 

 about the horse. 



Pompey told his story, and that his master 

 n 2 quarts of water, 30 grams had charged him to tell the horse's faults to 



the purchaser without reservation. 



" Well, what are they ?" said the stranger, 

 who had a mind to swap. 



" Dere is tour, Massa," said Pompey, "and

 "And the next?" 



"I don't anyhow remember de oders," said 

 Pompey, peering into the clouds with one eye, 

 reflectively. 



The stranger concluded to strike a bargain, 

 and exchange his own horse, which had not 

 quite so gentle an air as the parson's, for this 

 nearly perfect animal. It was not long be- 

 fore the clerical steed stumbled and threw his 

 rider into a ditch. Picking himself up as 

 well as he could, he examined his new pur- 

 chase a little more closely, and discovered that
