branches between the seventh and fifth, which formed the 
subject of the author's paper, pass to Meckel’s ganglion, the otic 
ganglion, and the submaxillary ganglion in Mammals; whereas 
in Batrachians they do not pass to these ganglions, but their 
junctions are effected among the terminal ramifications of the 
nerves. He could not agree with Prof. Huxley that the fore 
part of the skull was not, like the hinder part, composed of ver- 
tebral elements. It was transversely segmented after the 
manner of the rest of the skeleton, and these segments are 
vertebrae, whether the notochord exists at the part or not; and 
whether the segmentation takes place early or not, that is, in 
the cartilage or in the osseous nuclei developed in the cartilage, 
makes little difference. Sooner or later, in the higher animals 
at any rate, the segmentation occurs. The foremost elements 
derived from the trabecule had been designated as ribs by 
Prof. Huxley: and if they are so, they are components of those 
segments, of which the vertebra form the mesial elements. He 
could not quite accept the view of the homologies of the mandi- 
bular arch which had been given; but time failed to discuss 
these questions more fully. He concluded by again thanking 
Professor Huxley for this interesting communication.

Mr PEARSON read a paper on some meridian observations 
of the Sun taken by him with a prism-circle and an artificial 
horizon, at Taormina in Sicily, on April 1st last. They were 
taken with the view of determining the latitude of the place. 
The watch was set to Greenwich time, but about 8m, 9s.
