much more accurate, in some respects, than a drawing can be 

 expected to be. — Phil. Mag., Sept., 235. 



6. Preservation of Milk. — The following method is recom- 

 mended for the preservation of milk, either at sea or in warm 

 climates. Provide pint or quart bottles, which must be per- 

 fectly clean, sweet, and dry ; draw the milk from the cow into 

 the bottles, and as they are filled, immediatclji cork them well 

 up, and fasten the corks with packthread or wire. Then 

 spread a little straw on the bottom of a boiler, on which place 

 the bottles, with straw between them, until the boiler contains 

 a sufficient quantity. Fill it up with cold water ; heat the 

 water, and as soon as it begins to boil, draw the fire, and let 

 the whole cool gradually. When quite cold, take out the 

 bottles, and pack them with straw or saw-dust in hampers, 

 and stow them in the coolest part of the ship, or in a cool 

 place. Some years since, there was a Swedish or Danish 

 vessel at Liverpool, having milk on board preserved in this 

 manner ; it had been carried twice to the West Indies and 

 back to Denmark, and had been above eighteen months in 

 the bottles : nevertheless, it was as sweet as when first milked 

 from the cow. — New Monthly Mag., 316. 



7. Preservation of Caulifiowers. — These vegetables have 

 ■been preserved two or three months by digging a trench under 

 a wall, eighteen inches wide and deep, laying in the cauli- 

 flowers with the stems inclined upwards, and covering the 

 whole in with earth, heaping up the surface in an inclined form, 

 so that the rain should run oflT. 



8. Use of Larch Bark in Tanning. — Mr. E. Smith, from 

 repeated trials made by himself and friends, strongly recom- 

 mends the use of larch bark in tanning, not only for liglit calf, 

 deer, or sheep's skins, but for stout hides ; and states, that sole- 

 leather tanned with it, and worn against other leather tanned 

 with vallonia, resisted the wear better, and did not imbibe so 

 much water. He then asks whether there is any further occa- 

 sion for the importation of Dutch or German bark. 



9. Atkin's Rock. — The dangerous ledge of Atkin's Rock 

 has been marked and observed very accurately by Captain 

 Cork, of the Basnet, from Demerara to Liverpool. Its position 

 has not been determined exactly, but the Captain announces 

 its situation to be precisely 50° 5' latitude, and 12° west longi- 

 tude from Greenwich.

 removing frescoes from one wall to another without in-
