manner. Attention was also directed to a plant growing- 

 among the rocks, and gathered by Mr. Tepper, viz., Euphorbia 

 eremophila, which the Professor said was well known to the- 

 fcheepfarmer of the Par ISTorth on account of its poisonous- 

 dualities, but has rarely, if ever before, been seen in the 

 southern parts of the colony. 



At about 6 p.m. the coaches started on their homeward 

 journey, and the city was reached at an early hour. 



ForETH EXCUESIOX — EEBRrART 2, 1884. 



About 90 ladies and gentlemen proceeded in reserved car-^ 

 riages to Aldgate, from whence a special engine took them on 

 to Bridgewater. Here they were met by Mr. E. Guest, of Bal- 

 liannah, who had consented to undertake the guidance of the 

 party through the grounds of Messrs. Dunn & Co., who had 

 kindly granted permission. Eollowing the mill-race the direc- 

 tion towards Mount George was taken. Around the sheet of 

 water known as Dunn's dam, the following introduced plants 

 were noticed, viz., the ribwort (Plantago lanceolata), Dutch 

 clover (Trifolium repens), chamomile (Matricaria camomilla), 

 sheep's sorrel (Eumex acetosella), dock (E. obtusifolius), and 

 the yarrow (Achillea millefolium). An imsnccessful search 

 was made for a lamprey inhabiting Cox's Creek, and believed 

 to be a species at present unknown to the scientific world. The 

 following native plants were pointed out by Prof. Tate as rare, 

 viz., Siegesbeckia orientalis, Gratiola Peruviana, Prunella vul- 

 garis, Polygonum minus, Juncus prismatocarpus, Scirpus inun- 

 dntus, and one of the native fuchsias, viz., Correa decumbens, 

 the latter said to occur nowhere else than in the valley of the 

 Onkaparinga Eiver. 



An open-air meeting being called, presided over by Prof. 

 Tate, ten new members were elected ; and a few unimportant 

 business details being disposed of, the party proceeded towards 

 Mount George. On arriving at the summit, Prof. Tate stated 

 that the upper part of Mount George was a grand rocky bluff 

 of quartzose grits, as were also those of all the peaks in the 

 Mount Lofty Eange, whilst the slopes were composed of talcose 

 slates. The contour was obviously due to the difference of the 

 structure and composition of the two sets of beds. This bluff, 

 like all the high ground around, was covered with stringybark 

 forest, seemingly of one species, viz.. Eucalyptus capitellata, 

 corroborating the observations of Mr. J. E. Brown, E.L.8., in 

 the " Eorest Elora," that " trees of this species are more 

 numerous in the inland stringybark forests than those of its 

 compeer, E. obliqua." Eew shrubs and plants were in flower, 

 except Bursaria spinosa, a myrtaceous shrub ; and Ixodia
