things, cannot be despised with impunity ; and, whether we 

 consider the effects of its teachings in the abstract^ or as 

 applied to practical labours, we are equally persuaded of its 

 high importance. 



It will soon" be necessary to supply the towns near the 

 gold-fields with water sufficient for machinery and sanitary 

 purposes, and therefore minute observations in meteorology 

 in all these localities, have become of greater importance than 

 ever.^ If commenced at once they may be the means of 

 preventing endless disputes, and possibly saving a large 

 expenditure of public money.

Art. XVII.— ^ Description of Fossil Animalculce in Primi- 

 tive Rocks from the Upper Yarra District. By WiLLlAM 

 Blandowski, Esq. 



I HAVE the honour to lay before the members of the Philo- 

 sophical Society, a few specimens of rocks, containing minute 

 fossil remains, forwarded to the Society through me, by 

 Fred. Acheson, Esq. ; having been discovered by that gen- 

 tleman, on the left bank of Anderson's Creek, about a mile 

 from the junction of that stream with the Yarra Yarra. 



These specimens were procured from a vein about fifteen 

 inches in thickness, inclosed between layers of hard blue slate, 

 inclined at an angle of 75 degrees southward. They are 

 chiefly composed of coarse porous quartz, but those speci- 

 mens procured from larger blocks, or at a greater depth, are 

 dense and of a blue colour. In this state the rock assumes 

 a crystalline appearance, much resembling marble, and is 

 dotted with numerous specks of iron pyrites, which, becoming 

 decomposed by the action of the atmosphere, result in the 



* Since writing the above, I learn that Captain Clarke is about to establish 

 a system of Meteorological Observations, at the various Survey Offices through- 

 out the Colony, in connexion with the Observatory already established in Mel- 

 bourne. This is a step in the right direction ; such observations can be con- 

 ducted inexpensively, and with much accuracy, without any large sacrifice of 

 time on the part of the observers.
