OVI NATION WITH KXPOSUUK. 129 



A sheep having been placed in a shed for five days 

 \vith another laboining under variola, was inoculated 

 with lymph of the first remove, and still kept with the 

 diseased animal. On the fourth day the punctures had 

 taken ; on the seventh a rose-coloured efflorescence 

 came out, principally on the hairy parts of the integu- 

 ment, and subsided on the ninth day. This eruption 

 was unaccomimn'ied with anij constitutional disturbance, 

 and was not succeeded by impuJw. Vesicles formed on 

 the places of inocidation on the twelfth day, and under- 

 went the usual changes. Slight ulceration followed ; 

 but by the twenty-sixth day the sores were nearly 

 healed. 



We subjoin an account which is quoted by M. Vitet 

 from the report of an agricultural committee ; it 

 shews that similar experiments have been equally 

 successful. " We," say the committee, '' have seen 

 forty-five sheep inoculated with the sheep-pox indis- 

 criminately, mixed with others infected with the con- 

 tagion, without the effects of the claveUzation appearing 

 to be greater or more malignant upon them than upon 

 others which were kept apart after the operation*." 

 Although it does not appear that a separation of the 

 flock into two portions is made, when the natural disease 

 breaks out and inoculation of the unaffected animals is 

 had recourse to, still we should prefer such a plan to 

 that of allowing the sheep to herd together during the 

 time. 



Hurtrel *D'Arboval speaks of secondary eruptions. 

 We have not as yet seen a well-marked case of this 

 description, and therefore we prefer the insertion of 



* Hogg's Shepherd's Guide, p. 249 & seq. Edmburgh, 1807.
