1. (Authorised by the Government of France.) Melt 2 lbs. of suet in an earthen vessel over a slow fire, and add 2 lbs. of wheat flour, 3 oz. of levigated white arsenic, 2 1/2 drs. of lamp black, 15 drops of oil of aniseed. It may be used alone, or mixed with bread crumbs, etc. [For destroying rats and mice.']

2. For bam floors. Mix a pint of good flour with as much yellow arsenic as will lie on a shilling; put this in a small heap on the floor, and over this put another pint of good flour unmixed. Draw a track up to the heap with a feather dipped in oil of aniseed and oil of caraways, and sprinkle this over with a little flour.*

* The following is an old rat-catcher's receipt for oils to attract rats: -

3. Mix a quart of the best oatmeal, 2 oz. of powdered loaf sugar, 6 drops each of the oils of rhodium, caraway, and aniseed, and 1/4 gr. Musk. Mix them very perfectly without touching the mixture with the hands. Place in a retired spot 6 or 8 pieces of clean hoard, and on each, two tablespoonfuls of the powder, for a few successive nights, without disturbing the rats. About the sixth night, if they are found to eat freely, mix a teaspoonful of white arsenic with the powder. What remains in the morning should be burnt, avoiding the fumes. - The Chemist, vol. vi.

4. White arsenic 2 oz., carbonate of baryta 2 oz., white sugar 3f oz., rose pink 1/4 oz., oil of aniseed and oil of rhodium, of each 5 drops.

5. Malt flour 1 lb., oil of rhodium 3 drops, sugar 2 oz., 8 cloves, a tablespoonful of caraway seeds, all beaten in a mortar. Lay it in small parcels where they frequent, for 3 or 4 nights, till they eat freely, then add some arsenic dissolved in spirits of salts. - Mayer.

6. Ointment for Rats in Sicks. Mix together 1 lb. of fresh butter, free from salt, 1 1/2 oz. of calomel, 8 oz. of crumbs of white bread, 2 oz. of sugar, 5 drops each of oils of nutmeg and rhodium, and 2 drops of oil of aniseed. To use it, make a hole with the arm under the ridge; into this hole insert a stick, and on the middle of it, where it does not touch the rick, put a lump of the ointment. For Traps. Put the same with 2 or 3 drops of oil of thyme.

7. Hampshire Millers' Eat Powder. Mix 1 oz. of nux vomica in powder with a pound of fresh oatmeal, and add a few drops of oil of rhodium, or, what answers better, oil of aniseed with musk.

8. Philanthrope Muophobon. A French preparation so called, consists of 1 part of emetic tartar to 4 of farinaceous and other ingredients.

9. Put into a flask 2 drs. of phosphorus and 5 or 6 oz. of water, put the flask in warm water (about 150° Fahrenheit) till the phosphorus is liquefied; pour the contents into a mortar, and immediately add 5 or 6 oz. of rye-meal; when cool, add the same quantity of melted fresh butter, and 4 oz. of sugar. Two drs. of oil of aniseed, 2 drops of nitrons acid, and 2 grs. of musk. Oil of rhodium is also supposed to be very attractive to these vermin, Assa-foetida with these oils is sometimes used.

10. Another form of the phosphorus compound is: - Melt 1 lb. of lard in a bottle plunged into water, and heated to 150° Fahrenheit. Introduce into it 1/2 oz. of phosphorus and add a pint of proof spirit. Cork the bottle securely after its contents have been heated from 140° to 150°, and taking it out of the water bath, agitate it briskly till the phosphorus is uniformly diffused; repeat the agitation occasionally as it cools, and, when cold, pour off the spirit which has separated (which may be reserved for the same purpose), and incorporate with the fatty compound wheat flour and sugar. Oil of rhodium or aniseed may be added. Place little lumps of this in the rat-holes, and set some water near for them to drink. For a third receipt, see Phosphorus Paste for Vermin, further back.

11. Valentia almonds 1 oz., treacle 2 oz., carbonate of baryta 1 oz., oil of aniseed 5 drops, flour enough to form a paste.

12. Powdered squill 1/2 oz., strong cheese 2 oz. Mix and form into balls. For Mice.

13. Pulp of squills made into a paste with flour and dried, has been used as a poison for rats in France.
