latter it makes itself at home. Spores are formed under the 

 epidermis, and in two or three weeks from the time of germination 

 of the original spore they rupture the epidermis, and show 

 themselves as one-celled orange-yellow spores, the "rust" of 

 wheat. These are called uredospores, which do nothing but 

 multiply their kind, and so spread the rust by many rapid cycles. 

 Later on in the season are produced from these same rust spots, 

 after a series of changes and transformations, what are known as 

 resting-spores. These lie dormant till the following spring, and 

 are not active on the wheat plant itself. They make their winter 

 home on the leaves of other plants, notably the barberry. Hence 

 the action taken by the State of Massachusetts over a hundred 

 years ago in ordering the destruction of all barberry bushes to 

 save the wheat crops. On the barberry these resting-spores 

 undergo a double change, one of which results in the formation 

 of Cluster-cups, which on ripening in the spring or early summer 

 burst their envelopes and allow the active spores, with which they 

 are then filled, to escape and betake themselves to their deadly 

 work of " rusting " the neighbouring fields of wheat. 



"THE TOMBS, TEMPLES, AND PYRAMIDS OF EGYPT." 



The second meeting of the Winter Session was held in the 

 Museum, College Square North, on Tuesday evening, 17th 

 December, when an interesting lecture on " The Tombs, Temples, 

 and Pyramids of Egypt " was delivered by Mr. Thomas Plunkett, 

 M.R.I.A, of Enniskillen. The President (Mr. Robert Patterson, 

 F.L.S.) occupied the chair, and there was a large attendance. 



Mr. Plunkett, in the course of his lecture, which was fully 

 illustrated by lantern slides, said he was neither an artist nor an 

 architect, but for many years he had been deeply interested in 

 descriptions of the marvellous monuments and stupendous works 

 of art wrought in stone in the land of the Pharaohs at a period
