Callum's Tarn. — This is on the south-east end of Bute, about a 

 quarter of a mile northward of Callum's Bay, on the eastern side of 

 Callum Glen, 380 feet or so above the sea-level. The tarn is 

 about 200 yards long, and 50 broad, and is well filled with 

 vegetation. The greater part of the eastern side is firm turf, the 

 two ends and western side are softer, but can be worked with little 

 difficulty, and are the richest in Ostracoda. There are three other 

 smaller tarns on the same ridge towards the south, and another, a 

 short distance from the first, towards the north. These I have 

 found of little consequence — still they are worth a trial, for different 

 seasons gave different results, as below: —

Craigengower Tarn, on the hill-side, south of Craigengower 

 farm, Cumbrae. This patch of water may be about 30 yards long, 

 by about 15 broad. It is well covered with vegetation. The tarn 

 is tolerably firm round the margins, and may be 2 or 3 feet deep 

 towards the middle. Spiders and beetles are in abundance, and 

 at all times it may be calculated upon to yield a gathering of 

 Ostracoda of more or less interest, such as — y^C^ V A /
