Although it is foreign to the purpose of this note, it may be 

 wortli while to mention a few of the plants upon which the ex- 

 periments were made. Sections were taken of many of the grafts 

 and microscopic examinations made to determine the extent of 

 cell union. Coleuses of many kinds were used, with uniform suc- 

 cess, and the cions of some of them were vigorous a year after 

 being set. Even iresine, (better known as Ackyrantkes Versckaf- 

 fcltii,) united with coleus and grew for a time. Zonale gerani- 

 ums bloomed upon the common rose geranium. Tomatoes upon 

 potatoes and potatoes upon tomatoes grew well and were trans- 

 pi anted to the open ground, wdiere some of them grew, flowered 

 and fruited until killed by frost. The tomato-on-potato plants 

 bore good tomatoes above and good potatoes beneath, even though 

 no sprouts from the potato stock were allowed to grow 7 . Peppers 

 united with tomatoes and tomatoes united with peppers. Egg 

 plants, tomatoes and peppers grew r upon the European husk 

 tomato or alkekengi (Physalis Alkekengi). Peppers and egg 

 plants united with each other reciprocally. A coleus cion was 

 placed upon a tomato plant and w T as simply bound with raffia. 

 The cion remained green and healthy and at the end of forty-eight 

 days the bandage was removed, but it was found that no union 

 had taken place. Ageratums united upon each other with diffi- 

 culty. Chrysanthemums united readily. A bean plant, bearing 

 two partially grown beans, chanced to grow T in a chrysanthemum 

 pot. The stem bearing the pods was inarched into the chrysan- 

 themum. Union took place readily, but the beans turned yellow 

 and died. Pumpkin vines united with squash vines, cucumbers 

 with cucumbers, musk-melons with watermelons, and musk-mel- 

 ons, watermelons and cucumbers with the wild cucumber or 

 balsam apple (Echiuocystis lobatd). 



Another interesting feature of the work was the grafting of one 

 fruit upon another, as a tomato fruit upon a tomato fruit or a cu- 

 cumber upon another cucumber. This work is still under pro- 

 gress and it promises some interesting results in a new and unex- 

 pected direction, reports of which may be expected later.
