 Goadby's. It is simply Methylated spirit reduced to from 30 

 to 40 under proof, with creosote added in the proportion of 40

VIII. Notice regarding the Food of Patella vulgata, dbc. By John 

 Alex. Stewart, Esq., Lochcarron. Communicated by Andrew 

 Murray, Esq. 



The object of this paper was to show that the Patellce were 

 not purely phytophagous, but also carnivorous. In support 

 of this view Mr Stewart narrated some observations made by 

 him, when he had seen the Patella vulgata rasping away at 

 the young Balani with which the rocks were covered, and he 

 sent for exhibition to the Society the contents of the stomach 

 of P. athletica and P. vulgata, taken near Lochcarron, in the 

 north-west of Scotland. Among the contents of the stomach 

 of P. vulgata, were fragments of the shells of young Balani; 

 on the other hand those of P. athletica seemed almost entirely 

 composed of Corallina officinalis, 



Mr Stewart's paper also contained some interesting details 

 as to the Patellar returning habitually to rest on the same 

 identical spot, so as to leave its impress quite distinct, while 

 all the rock around was overgrown with Balani, &c. 



IX. Dumfriesshire Graptolites, with Descriptions of three New Species. 

 (A collection of these fossils were exhibited.) By William 

 Carruthers, Esq. 



At the meeting of the British Association held at Edinburgh 

 in July 1850, Professor M'Coy read a list of the then known 

 Graptolites of the south of Scotland. They amounted to four- 

 teen species. My examination of the graptolitic shales has 

 been chiefly confined to those which occur in Dumfriesshire. 

 In this district the following Graptolites, amounting to twenty- 

 four species, have been found : — 



Rastrites peregrinus, Barr. Bran Burn, Dobb's Linn, 

 triangulatus, Hark. 



This is a remarkably abundant fossil at Garple Linn. Having 

 examined a large number of specimens from this locality, and 

 been unable to discover anything approaching the form G. 

 SedgivicJcii, I am satisfied that this is a distinct species, and have 

 consequently inserted it in this list.
