the results. Pods, grown from this seed in a factory in Manchester, 
the heat of which varied from 100° to 56° Fahr., unripe, because of 
insufficient heat and a bad atmosphere, were laid upon the table. The 
were of good size as compared with those grown in the Sea Islands of 
the American coast, and if fully ripened the staple would be of great 
length. These pods were stated to be of twice the size of those of 
Bengal producing the short staple. The object of the experiment was 
to ascertain if the length of the staple could be secured elsewhere than 
in the Sea Islands, the other circumstances attending the growth of the 
plant being made as similar as possible. It was conducted by Thomas 
Bazley, jun., Esq., Boroughreeve of Salford, an eminent cotton-spinner 
of Manchester. 
The following particulars relating to the course of the experiment, 
were offered to the notice of the Section. The seed was sown in April 
1840; but if sown the preceding winter it might have been better. 
Transplanted in May. The earth was formed of two-fifths river-sand, 
two-fifths light soil, one-fifth horse-manure ; fifteen inches in depth was 
found too shallow, and thirty inches is recommended as preferable. 
This soil was kept in a decidedly moist state by frequent sprinklings 
of the plants with a solution of one ounce of common salt in a gallon 
of water. The plants in America are found in the driest season 
saturated in the morning with dew. The plants in Manchester are 
five feet high, well spread out; showed in July the usual bright 
scarlet and yellow-coloured flowers, and became full of pods in August. 
A number of male and female plants grow together. 
Remarks on the Synonyms and Affinities of some South African genera 
of Plants. By G. A. Waixer Arnott, LL.D. 
The object of these remarks was to prove,—Ilst. That the Placourtia 
rhamnoides of Eckl. and Zeyh., and perhaps also of Burchell, was the 
Doryalis zizyphoides, E. M., and approached more to Euphorbiaceze 
than to either of the orders with which it has been associated. 2nd. 
That the genus Schmiedelia (or Ornitrophe) does exist in South Africa, 
although omitted from the floras; and that several of Thunberg’s and 
E. Meyer's species of Rhus belong to it. 3rd. That Hippobromus is also 
a Sapindaceous genus. 4th. That Hriudaphne of N. ab Esenb. is iden- 
tical with Phoberos, Lour. 5th. That Z’rimeria of Harvey has been 
already but erroneously described by Sprengel as a Celastrus. And 6th. 
That Ophira of Linn. is the same as Grubbia, Linn.; but that Ophira of 
Lamarck’s ‘Illustrations des Genres’ is a very distinct genus, which 
has been lately described by Dr. Klotzsch of Berlin under the name of 
Strobilocarpus ; and that the true structure of these genera appears to 
ally them on the one hand to Hamamelidez, and on the other to San- 
talacez, to which last, if Dr. Klotzsch’s analysis were quite correct, 
they would decidedly belong.
