Feldspathic Sandstone Flagstone from Near Hudson Hope, Northern British Columbia - Potential for Sandstone Production in British Columbia
There are a number of well-established flagstone and dimension stone producers supplying the existing market in Western Canada and adjacent US states. Such products are distributed in pallets of approximately 1 cubic metre (around 2 metric tonnes) (Photos 1, 2 ), sorted by thickness and degree of processing, such as with or without sharp edges, random or square shapes, etc. The BC and Alberta products are complemented by imported stone types not available from local producers.
Report on the Building and Ornamental Stones of Canada
THIS volume constitutes the third part of the monograph on the building and ornamental stones of Canada, and worthily upholds the high standard established in the earlier portion of the work. The greater part of this report is occupied by a systematic account of the quarries of the maritime provinces and of their products. The stones are considered according to the class to which they belong, e.g., granite, black granite (greenstones), sandstone, limestone, &c., and arranged according to more or less definite geographical areas into which the quarries o naturally fall. In order to give prominence to the economic and commercial aspect of the work, the quarries are described under the name of the owner wherever possible. The general plan adopted for the description of individual properties is: (a) quarry observations; (b) description of the stone, with tests; (c) economic remarks and statistics; (d) examples of the use of the stone. Sketch maps are given showing the geology and location of quarries in important districts; special mention must be made of the excellent colour-photo plates which show in an admirable manner the colour and appearance of the stones, a feature which should be appreciated by architects.Report on the Building and Ornamental Stones of Canada.Vol. ii., Maritime Provinces.

Diagnostic and therapeutic studies on chronic diarrhea in dairy animals
The study was conducted to determine the etiology of chronic diarrhea in dairy animals. Seven causes of chronic diarrhea were established in dairy cattle and buffaloes. Balantidiasis in 37.6 per cent, dietary diarrhea in 9.9 per cent, chronic salmonellosis in 6.9 per cent cases of chronic diarrhea, secondary copper deficiency and amphistomiasis in 6.9 per cent, clinical Johne‘s disease in 3.9 per cent and chronic peritonitis in 2.97 per cent of dairy animals, manifest chronic diarrhea. The precise diagnosis could not be established in 24.50 per cent of animals. Lymphosarcoma was confirmed in one of the dairy cattle. Body condition score was associated to the etiology of chronic diarrhea. B. coli infected cattle and buffalo revealed cysts in 32.3 per cent cases while 5 per cent positive cases revealed both cysts and trophozoites. Mean cyst count was 2.73±0.91 hpf in diarrheic animals compared to 0.11±0.447 hpf in healthy animals. Clinical Johne‘s disease was confirmed in four animals. Hematological changes revealed anemia and neutrophilia with morphological changes suggestive of regenerative to degenerative left shift. High plasma phosphorus, hypoproteinaemia and hypoalbuminaemia was seen in clinical Johne‘s disease. Salmonella isolates showed higher in-vitro sensitivity to enrofloxacin (87%), ciprofloxacin (87%), gentamicin (75%), and tetracycline (66.7 %) and were resistant to ampicillin and amoxicillin. Mean cyst count reduction from 2.41±1.16 to 0.11±.33 was observed in oral metronidazole treated group where as reduction of mean cyst count from 2.73±0.918 to 0.18±0.44 in intravenous metronidazole treated group. Recovery rate with oral and intravenous metronidazole was 42.1 and 63.1 per cent respectively. Recovery results in significant decrease in eiosionphil count and increase in total plasma protein in both oral and intravenous treatment groups. Complete recovery response approaches 60 per cent in balantidiasis affected adult dairy animals. Balantidiasis was the major cause of chronic diarrhea and intravenous administration of metronidazole was more effective than oral metronidazole.
