one-eighth of an inch for every degree wanted. If a lower temperature is 
desired, raise the valve a trifle. 
9. Trim and cut the wick of tlie lamp every twelve or eighteen hours. 
Always remove the wood slide on which the lamp rests, before trying to take 
the lamp away, and the tighter a lamp fits up into the chimney, the better it 
will burn. Remember never to quite fill the oil reservoir. Cut the wick level, 
just shaving off the extreme sharpness of the comers. What is required is a 
broad flat flame reaching almost from side to side of the lamp chimney. If 
the least point or horn of flame ap^jears when turned up, the lamp is not 
properly trimmed. No part of the flame must ever touch the boiler. After 
burning a few minutes, the flame of oil lamps increases slightly, therefore 
never turn to the highest possible point, or the slightest rise will put the 
flame against the boiler and cause smoke.* 
10. Turn the eggs twice a day for the first ten days, afterwards once only 
is necessary, and always turn them before trimming the lamp. When 
turning in the morning, cool the eggs for five or ten minutes. Keep the 
heat in the egg-drawer as near 104° as possible. 
11. Replenish the water tray under the egg-drawer with just warm water 
(80°) about every other day, and at the same time fill up the main tank at f 
till it overflows. 
12. For the lamp, use good parafiin, kerosene, or crystal oil, and wipe dry 
and clean each time after trimming the wick. 
13. To empty the machine of water, undo the screw cap at bottom, or turn 
the machine over on its side. 
14. If it is desired to detach the lamp chimney at any time, lay the 
incubator on its side and tmdo the unions. 
15. The bulb of thermometer must be on the level of the top of the eggs, 
or you must make an allowance. For instance, if with a thermometer at the 
ordinary level (1^ inches from the floor of the drawer) you put in pheasant's 
eggs, you must work at 106° to 108° to give 10-4° on the top of the pheasant's 
eggs. 
16. The thermostatic band q acts from the dotted line (see sectional drawing) 
downwards. See when starting that c protrudes about an inch above the 
lever, else q must be bent by placing the fingers of both hands above the 
broad band q, and pressmg it upwards with both thumbs. If you bend up 
the band, such bending must be done at the back. The band itself should 
be kept straight from where it joins the rod c to the other end, where the 
bend is. Price, for 100 eggs, 8Z. ; for 50 eggs, 6?. 
Mr. John Myatt, Berryhill, Stone, Staffordshire, exhibited a 
Sheep-Dipping Apparatus, with a Drainer on an entirely novel 
principle. The dipping-tub is of the ordinary shape, with a 
sloping end for the sheep to walk out on to the drainer. The 
drainer is circular-shaped, and divided into six compartments ; 
each compartment drains into a grated pipe in the centre of the 
drainer, which conveys the liquid back to the tub. The drainer 
is made to revolve, and each sheep as it comes round to the 
place of exit, which is placed immediately behind the place of 
entry, is sufficiently dry to be allowed to go. The table requires 
to be placed level. There may be some question as to the move- 
ment of the sheep interfering with the equilibrium, but this could 
only be ascertained by experiment. The price i« 12Z. 12s.
