Lord John Townshend's Poetical Works

Can any of your readers inform me whether the poetical works of Lord John Townshend, M.P., were ever collected and published, and, if so, when, and by whom? His lordship, who, it will be remembered, successively represented Cambridge University, Westminster, and Knaresborough, was considered to be the principal contributor to the *Rolliad*, and the author of many odes, sonnets, and other political effusions which circulated during, the eventful period 1780-1810.
