no matter where you went, if you came to any particular horizon, 
there also was the " whin sill." In places we were shown that they 
crossed the strata ; but this must occur with all contemporaneous sheets ; 
as it is nearly unnecessary to point out that a rock coming up from 
below must cut across all rocks below its geological horizon. None of 
these sheets, however, cut up into the strata above their horizons. 
In support of their assertions in connexion with their " Old Boy," 
*'the shearers" pin their faith very much on the peculiar ''Moine 
or Eastern schists." These schists undoubtedly are most remarkable 
rocks, but in connexion with them we were asked to believe far more 
than could be proved. The " Moine schists" are said to be attenuated 
or torn-up Old Boy," Torridon sandstone," Pipe quartzite," and 
''Durness limestone." 
We were shown the "Old Boy" passing into these schists; we 
were also shown the basal bed of the Torridon sandstone passing into a 
rock very similar. This locality is worthy of special notice. The basal 
conglomerate lies on the " Old Boy," and both are changed into rocks 
that might be called " Moine schists." But the tearing up is not what 
ought to he expected, as the boundary between the rochs of the two distinct 
periods is nearly intact, only being a little serrated. Considerable por- 
tions of the Moine schist are quartzose rock, that possibly may be 
attenuated pipe quartzite, while we were also shown the Durness 
limestone becoming attenuated; but our instructor totally failed to 
show us in the ''Moine schist" any rocks that could represent the 
torn-up Durness limestone. We were told we could see it in the Loch 
Maree district, but when we went there, we found this supposed torn- 
up Durness limestone to be an intrude of calcareous whinstone. 
Connemara District. — Prom the already given quotation from the 
Paper of Dr. Geikie, we learn that he and his assistants have 
proved that my conclusions are wrong. As Dr. Geikie refers to an 
area in which, as far as he saw it, all the rocks are metamorphosed, 
he is so far safe in saying that there are ' ' no conglomerates, no sand- 
stone, no shales," as all that he saw have lost their normal characters. 
This, however, may not be the case with rocks he did not see fur- 
ther southward, in Goroman and Lettermullen. However, his state- 
ment, that not even any materials that might be supposed to represent 
them also in a metamorphosed condition occurs, is perfectly incorrect. 
His statements as to the metamorphosed fragmentary rocks are quite 
at variance with those of the scientists who have made such rocks 
their special study. Even in Sutherland the altered and attenuated 
Torridon conglomerates have characters in common with those of the
