which should immediately be picked up and burnt. The soil should be 

 dressed with kainit (half a pound to a square yard), between the middle 

 and end of June, either just before or after rain. In the case of very 

 dry weather at that, time the dressing should be watered-in after it has 

 been applied." 



Apples, shrivelled. — Mr. Saunders reported as follows on some Apples 

 exhibited : — " The little shrivelled Apples had certainly been attacked by 

 some insect, but they did not contain any when I opened them. I should 

 imagine from their appearance that they had been infested by the grubs 

 of the ' Apple Sawfly ' (Hoplocampa testuclinea). These little grubs, 

 when full-grown, bury themselves in the earth at a depth of from two to 

 four inches. All the little Apples that fall naturally, or can be shaken off 

 the trees, should be at once collected and burnt ; it is of no use merely 

 throwing them away. If the roots of the trees are not very near the 

 surface, the soil, from under such parts of the tree as the grubs are likely 

 to have fallen from, should be removed in the course of the winter, and be 

 burnt or buried deeply, so as to prevent the sawflies from leaving the 

 chrysalides. The sawflies are about quarter of an inch in length, and 

 measure about half an inch across the wings. The insect is black above 

 and yellowish-red beneath, and has four wings." 



Crinum sp. — Mr. Elwes, F.R.S., exhibited an umbel of very fine flowers, 

 having the perianth white, with a median crimson stripe. The bulb came 

 from Brazil, and it appears that Mr. Goodman found it also in Jamaica. 

 He suggested that it might be C. Kirkei from Zanzibar. Mr. Elwes 

 remarked upon the wide diffusion of several African bulb plants in the 

 last century. 



Iris, malformed. — Mr. C. T. B. Crews, of Wokingham, sent a specimen 

 with double flowers. Dr. Masters undertook to examine it, and reported 

 as follows : — " The flowers presented a very remarkable appearance, owing 

 to the presence of an inordinate number of petaloid segments arranged in 

 a complicated and confused manner. Some of these segments were 

 partly staminoid, others partly stylar, but the majority were purely 

 petaloid and variously contorted. The ovary was inversely pyramidal in 

 shape, marked externally by six longitudinal ribs. The three ribs which 

 run into the sepals had a prominent knob just as they passed into them, 

 and in some cases there were other similar, but much smaller, knobs on 

 the petaline ridges. The ovarian cavity appeared to have an irregular 

 number of compartments, with some apparently normal ovules, and others 

 more or less petaloid. The sepals and petals were normal in character, 

 the disturbance in the growth having taken place subsequent to their 

 formation." Mr. Crews states that this plant has now borne similar 

 double flowers for four years. 



Leucadendron, malformed, — Professor Henslow showed an inflorescence 

 in which, instead of flowers, the peduncles were covered with bracts like 

 the " wheat-ear " Carnation. It was from a bush growing on the flanks 

 of Table Mountain. 



Sycomore Fig. — Professor Henslow showed specimens of this Fig, 

 which is always infested with Sycophaga crassipes. To remove them, the 

 Fig is cut open by a peculiar hook-shaped instrument ; the process also 

 causes the Fig to acquire great sweetness. The Figs are only cut open
