520 NOTES AND EXHIBITS. 



tubes can be removed, and replaced with fresh ones, and the 

 operation repeated. After every filling, a small quantity of 

 lymph remains in the rubber tubing B. This is removed, with 

 every subsequent exhaustion, into tube C. When sufficient 

 lymph has collected there, it can be readily withdrawn, and used 

 over again by screwing down the clamp on tubing G, and opening 

 clamps Dj and F. Clamping tube G cuts off the exhaust and no 

 capillary tubes must be placed in B. Filling the tubes by 

 gravitation is very much simpler than the exhaustion-method. 

 It is also much slower (the exhaustion is almost instantaneous), 

 also open capillary tubes must be used. Fill up the funnel or reser- 

 voir A with lymph. Insert the capillary tubes. Keep clamp 

 D x closed. Now open clamp D slowly. Watch the lymph rising 

 in the tubes, close D as soon as it reaches to \ inch of the top of 

 the tubes. With a portable peep-light, seal the end of each. 



Mr. A. A. Hamilton exhibited some examples of Teratology, 

 from the Collection of the National Herbarium, comprising Rosa 

 Hort. var., Sydney Botanic Gardens(W. Challis; August, 1913), 

 showing complicated prolification of the flower. The suppressed 

 ovary is represented by an expansion of the flower-stalk, the 

 sepals are leaf-like, the lower petals reflexed, the upper ones 

 unaffected; the axis is prolonged, and bears a circlet of miniature 

 roses, each with a leafy calyx; a few coloured petals, and foliar 

 staminal and carpellary organs are present, the axis finally 

 terminating in a tuft of leaves. — Plantago lanceolata Linn., 

 Petersham(T. Steel; June, 1906), showing foliar prolification of 

 the inflorescence, a tuft of leaves occurring on the apex of the 

 flowering- spike, after the maturation of the fruit. — Dodoncea 

 peduncularis Lindl., showing foliar prolification of the flower. 

 An example of the male inflorescence of a dioecious plant, in 

 which the calyx is normal, and the stamens replaced by a whorl 

 of leaves. 



Miss Hynes showed a specimen of Coccoloba (Micehlenbeckia) 

 platyclada F.v.M., exhibiting xerophytic characters. When grown 

 in a dry situation, the stems, as well as the branches, function as 

 leaves.
