11th February, 1835.--A Persian bitch, at the Zoological Gardens, who was well yesterday, now staggers as she walks, and has nearly lost the use of her hind legs. Gave a good dose of the castor-oil mixture. 18th. She is materially worse and drags her hind legs after her. I would fain put on a charge, but the keeper does not like that her beautiful coat should be spoiled, and wishes to try what gentle exercise will do. She certainly, after she has been coaxed a great deal, will get on her legs and stagger on fifty yards or more. Gave the castor-oil mixture daily. 19th. She is a little stronger, and walks a little better. Continue the mixture. Embrocate well with the rheumatic mixture--sp. tereb., sp. camph., liq. ammon., et tinct. opii--and give gentle exercise. 2d March.--She does improve, although slowly; the charge is therefore postponed. Continue treatment. 30th. She is considerably better. Continue the mixture, and use the embrocation every second day. 10th April--She has mange in the bend of her arm, and on her chest. Use the sulphur ointment and alterative balls, and omit the embrocation and mixture. In less than a week she nearly recovered from her lameness, and ran about almost as well as ever. 30th. She runs about very fairly, but the mange has assumed that character of scurvy which I do not know how to grapple with. Continue the alterative balls, and the ointment. 18th May.--The mange has disappeared, but the palsy is returning; she staggers slightly, and droops behind. Give the castor-oil mixture and use the embrocation. 14th June.--Mange quite gone, but palsy continues to a very considerable degree. I want to use the plaster; but the keeper pleads for a little delay. Continue the treatment. 1st July.--I have at length determined to have recourse to the charge. A piece of thick sheep's leather was fitted lo her loins and haunches. 18th. She appears to be improving, but it is very slowly. 31st. Very little change. The plaster keeps on well: she has no power over her hind limbs; but she eats and drinks as well as ever. 23d August.--No change. Give her half a grain of strychnia, morning and night. 26th That singular secretion of milk, to which the bitch is subject nine weeks after oestrum, is now appearing. Her mammæ are enlarged, and I can squeeze a considerable quantity of milk out of the teats. Give an aloetic pill, and continue the strychnia. 31st. The secretion of milk continues. There is slight enlargement and some heat of the mammæ; but she feeds as well as ever. Increase the dose of strychnia to three-quarters of a grain.
