does not hold good for tlie trachytes of Auvergne, and for those of 

 the Grrecian Islands, where much more recent cycles of eruption 

 have occurred. 



I'hese cycles of eruption may also be followed back into earlier 

 times, into the Secondary epoch, or into the Palceozoic ages, and I 

 have already satisfied myself that the series of felspathic rocks at 

 different periods is often the same. 



The basalt of Hungary seems to be an episode of the great 

 trachytic formation, derived from a lower hoi'izon, but nevertheless 

 related to the trachytes. In Hungary the basaltic eruption has 

 terminated the volcanic action, during and even after the deposition 

 of the couches a congeries (Pliocene). 



The anorthite-trachyte forms more than 50 per cent, of the trachytic 

 mass ; the labrador-trachyte 30 per cent., the oligoclase-trachyte 15 

 per cent., and lastly the orthose-trachyte 5 per cent. The first of 

 these is, therefore, the most important, inasmuch as it still forms the 

 highest trachytic mountains of the district (sometimes with an 

 elevation of over 6000 feet) ; moreover we may for the most part 

 attribute to it those secondary actions which have modified the other 

 types.

WE must confess to some disappointment in turning over the 

 pages of this work, but our disappointment is caused by what 

 is generally considered to be a fault on the right side, inasmuch 

 as the author in his text has given us far too little of his personal 

 experiences. Few men have seen more than Mr. Lee of sections 

 and districts that have been rendered famous by the descriptions 

 given of them by our leading geologists ; and if he has for the 

 most part followed in the footsteps of others, he has himself rendered 

 good service to science by the magnificent collections he has made. 

 In his museum are included not a few specimens new to science, 

 and many others personally obtained, which have enlarged our 

 knowledge of the fossil fauna and flora of particular districts. Some 

 of them are shown in the plates now before us. Nor can we con- 

 template the illustrations which form the bulk of this work, without 

 a feeling of reverence, taking us back as they do fifty years or more, 

 when the study of geology was cultivated by the few, mostly men of 

 means and position. 



The author speaks with afi'ectionate regard of John Phillips, to 

 whom he owed his earliest geological lessons, and in whose company 

 he spent many of the happiest hours of his life. In the preface to 

 his work on the Palaeozoic Fossils of Coi'nwall, Devon, and West 

 Somerset (1841), Professor Phillips acknowledges the assistance he 

 had received from Mr. Lee, who had at that time laboured very
