PODISOMA JUNIPERI AND RASTELIA LACERATA, 
Exp. 4.—Two thorn seedlings (Crataegus oxyacantha) infected on 10th April 
with Podisoma juniperi. On 24th abundance of spermogonia; on 25th May perfect 
Restelia lacerata on both these plants. 
Exp. 5.—Three similar plants were on 7th April infected with Podisoma 
junipert very freely. 24th April the leaves were yellow with spermogonia; 25th 
May perfect Restelia was produced. ’ 
Exp. 15.—Two similar plants infected on 17th April. On 6th May sper- 
mogonia noted, and on 3rd June the perfect Restelia on both plants. 
Exp. 16.—Three similar plants infected on 17th April. On 6th May sper- 
mogonia noted, and on 3rd June the perfect Restelia on all these plants. 
Exp. 27.—On 11th May the leaves on the lower branch of a hawthorn tree in 
Mr. T, Pung’s garden were infected with Podisoma juniperi. On the 21st the 
spermogonia appeared on five leaves, which in due time developed into the perfect 
Restelia. Onno other part of this tree, nor on any other thorn, either bush or - 
hedge, in this garden, was any specimen of either the spermogonia or the perfect 
fungus to be seen. 
GYMNOSPORANGIUM JUNIPERI AND RA@STELIA CORNUTA, 
Exp. 43.—Five small plants of Sorbus aucuparia were on the 29th May 
infected with Gymnosporangium juniperi, sent by the Rev. James Keith from 
Forres ; on 25th July spermogonia appeared on three leaves; on 4th September 
the perfect Restelia cornuta was observed. 
Exp. 44.—Five similar plants were infected on the 29th May. On 21st June 
yellow spots appeared; on lst July spermogonia were seen, and on the 4th 
September the perfect Rwstelia. 
Exp. 63.—One small mountain ash (Sorbus aucuparia) was infected on the 12th 
June with Gymnosporangium juniperi, sent by Rev. J. Keith from Forres. On 16th 
August spermogonia were noted. 
Exp. 73.—A similar plant was on the 18th June infected with the same 
material. On 1st July spermogonia appeared, and on 30th August the perfect 
Restelia. It should be observed that I had never seen this fungus in Norfolk until 
it was produced by artificial infection with the Gymnosporangium. 
PUCCINIA GRAMINIS AND AUCIDIUM BERBERIDIS. 
Exp. 11.—On 14th April a three-year-old plant of Berberis vulgaris was in- 
fected with the germinating teleutospores of Puccinia graminis (on Triticum repens), 
and covered with a large bellglass. As the supply of infecting material was on 
this occasion limited, the process was completed on the following day (the 15th), 
and on the 17th. The bellglass was not removed until the 24th. On 6th May 
spermogonia appeared, and on the 24th the perfect Mcidium was noted on 20 
leaves. A precisely similar barberry kept asa control plant had no Zeidium upon 
it, although grown in the same garden, and carefully observed throughout the 
summer, 
Exp. 14.—A similar barberry plant was on the 17th April infected with the
