pay the expenses of their transportation, and asked that the 

 pendulums should be sent as soon as possible. Mr. Wipple now- 

 stated that they would cost about £24 or £25 to pack and send 

 away, and as he did not know whether the vote would cover that 

 amount, he would await a reply. That was how the matter 

 stood at present. The information given by Sir George Stokes 

 would be very valuable in helping them to decide what was to be 

 done, and he was inclined to think that the work would be more 

 valuable and likely to be better done if new pendulums were 

 made. A great deal of trouble had been experienced with the 

 old pendulums in India, and they had seen a good deal of work. 

 The Americans when near Australia a few years ago had 

 used a small invariable pendulum made in America for their 

 observations, but so far as he had been able to ascertain, the 

 work was not very satisfactory. 



Mr. Love said that from the drawings he had seen, he thought 

 the construction of the Russian pendulum was very bad. From 

 an engineering point of view, it was weak where it should have 

 been strong, and vice versa. He objected more particularly to the 

 shape. As a matter of strength of materials, it w^as just as bad 

 as it could be. 



Mr. A. H. S. Lucas, M.A., B. Sc, read a paper entitled 

 " Notes on the distribution of Victorian Frogs, with description 

 of two new species." 



Dr. Dexdy said Mr. Lucas was to be congratulated on his 

 woi'k in connection with Victorian vertebrates. He had now 

 added very materially to our knowledge of the higher animals of 

 N^ictoria, and several new species were due to his researches. 



Mr. White said that forty years ago the noise made by the 

 frogs at St. Kilda could be heard miles away. 



Mr. Lucas said he thought the noise was made by the green 

 and gold bell frog. The connnon frog was a tree-frog, w-liich had 

 taken to the water. Its discs, which, though reduced, were still 

 pi-esent, showed that it belonged to that order. The green and 

 gold frog was the loudest. 



Dr. Dexdy said that at the University many hundreds of frogs 

 were used in the dissecting-room, and they found that the male 

 frog's vocal organs were much more largely developed than the 

 female's, and in a diffei-ent form, and specially adapted for making 

 a o-reat noise. He inferred from this that the male did most of 

 the croaking. 



Mr. Lucas said that that was so
