this cause that many larvae were in the evening found straying down 
away from the tree. 
May 10th. Minimum temperature during night upstairs 54°; 
at 8 a.m. in sunshine 70°—80°; at midday 60°. T received by the 
morning post a box from the Society of Acclimatization of Great 
Britain containing five parcels of eggs of Yamamai, done up in 
paper, consisting ndepectively of 113, 99, 102, 101, 98, besides 22 
eggs that were gone kt in all 585. ‘The box was packed with paper 
SHaviagss : on examination of these eggs 102 were much depressed 
in the centre, and had the appearance of unfertile eggs; but the 
remaining 433 seemed sound. These eggs were placed along 
with the other eggs, on bibulous paper 3) moistened under a 
glass funnel, but kept in a separate lot.* About 3 p.m. two larvae 
emerged from these eggs, fine healthy-looking larvae, and were 
placed on a little seedling oak in the greenhouse, after the hydro- 
pulting had been done. During the morning a larva just emerged 
was placed on a young Ailanthus tree, now fairly in leaf, growing 
in a pot placed in the room upstairs; this was done to see if 
that food would nourish the larvee. It was observed that, after 
emerging, the larve would drink freely; some larve upstairs 
were noticed to be drying up, though the tree was freely syringed. 
May 11th. Minimum temperature during night upstairs 57°, 
a dull rainy morning, no sunshine; eleven larve emerged; of 
these one was born about 10 p.m. the preceding night. No eges 
hatched out of lot No. 4, which contained the eggs sent to me by 
the Society of Acclimatization ; the syringe was ised freely ; the 
larvae seemed to have recovered from their dry state, but they 
are great vagabonds. My method of syringing was now altered. 
I placed the flower-pot ina round shallow japanned bath, and used 
an eye-douche to syringe with; by directing the nozzle upwards 
a shower of quasi rain drops was directed to fall successively upon 
all parts of the tree. The fluid was propelled by means of pressure 
made by the hand on an India-rubber bottle; on removing the 
hand the consequent expansion of the sides of the bottle sucked 
in a fresh supply of water through a tube at the bottom, and fresh 
pressure produced another shower. This apparatus was very 
convenient for the purpose. The superfluous fluid was after- 
* It was noticed of these eggs that many had little pieces of cardboard or 
paper attached to them, as if they had been originally deposited on cards. 
The glass funnel was placed over the eggs partly to maintain a more moist 
and equable temperature, partly to prevent the young larve from straying, 
and partly because the smooth surface of the glass offered no firm foot-hold 
for the young larva, which were therefore easily detached and removed to 
the oak- leaves.
