flour of sulphur, quarter of a 

 pound of elecainpane, three ounces 

 of liquorice, and a quarter of a 

 pound of anniseeds are to be ad- 

 ded m a pulverized state. This 

 preparation should be administer- 

 ed in milk, and the quantity here 

 stated is said to be sufficient for 

 six doses. 



" But the most effectual preven- 

 tive of this contagion is to keep 

 the cat(ie cool during the summer, 

 and to allow them a sufhciency of 

 water : all carrion should be spee- 

 dily buried : and as the feeding of 

 those useful animals in wet places, 

 or on rotten grass or hay frequent- 

 ly '"auses this maladj', their food 

 ought to consist of dry and sweet 

 fodder." — Domestic Encyclopedia.

NAVEL GALL, "a disorder 

 on the top of the spine, opposite 

 to the navel, whence the name. 

 It is most commonly caused by an 

 ill formed saddle, or want of good 

 pads, and being neglected turns to 

 a foul fungous excrescence ; and 

 sometimes, after long continuance, 

 to a fistulous ulcer. While there 

 is moisture and sensibility in the 

 part, an ointment may be applied 

 of quicksilver and turpentine ; an 

 ounce of the former or two ounces 

 of the latter, rubbed in a mortar 

 till they be well incorporated ; and 

 then spread upon tow. On each 

 side of the spine, over the swelling, 

 may be laid smooth dry pledgits, 



or holsters, which may be girt 

 round with a sursingle. But if the 

 sore be dead and lifeless, a good 

 sharp knife must be used to cut it 

 to the quick ; then let it be dress- 

 ed according to the directions for 

 the cure of wounds. 



'"^ sit fast also proceeds from a 

 saddle gall, and is another of the 

 accidents that happen to the spine. 

 It is dry and horney, and may be 

 cured by anointing it first with oil 

 of bays, until it turns soft ; then by 

 dressnig it with quicksilver and 

 turpentine, as above directed. 

 This will make a cure, especially 

 if the hard horney substance be 

 gently scarified in some places."

NETTLE, Uriica. This ge- 

 nus of plants is said to comprise 

 fifty-seven species. We shall men- 

 tion only the common nettle, which 

 has a fibre, said to be finer and 

 stronger than that of hemp. Dr. 

 Willich says, " The roots of the 

 common nettle, when boiled, com- 

 municate a yellow tinge to yarn. 

 But the most valuable part is its 

 fibrous staik or stem ; which on 

 being dressed in a manner similar 

 to flax or hemp, has in some parts 

 of Europe been advantageously 

 manufactured into cloth. As, 

 however, this plant requires a rich 

 soil to obtain it any great quanti- 

 tities, and as a much greater degree 

 of attention and accuracy is neces- 

 sary in the operation of retting, 

 than is requisite either for flax or 

 hemp. Dr. Anderson is of opin- 

 ion, that the cultivation of the 

 nettle will be attended with diffi- 

 culty." — Domestic Encyclopedia.
