“Beautiful Forms in Nature,” which is being issued in parts, 
under the editorship of Professor Heckel, of Jena, through whom 
it had been obtained. On the motion of the Chairman, the Hon.

fessor Heckel the thanks of the Society. 
Mr. John Renwick reported on an excursion to Callander, and 
Mr. Richard M‘Kay on one to Milngavie.

fruits, and also the following :—The fruits of Poinciana regia, Boj., 
Hura crepitans, Linn., Bryophyllwm calycinwm, Salisb., a plant 
belonging to the Crassulacee which forms buds on the margins of 
its leaves ; the fungus Cordyceps Robertsii, growing on the cater- 
pillar of a species of Hepialus ; and the fibre known as “Sisal,” or

America and Greenland should also occur in the West of Scot- 
land.
